Food prices up over crisis

are also wary of going to insecure areas for fear of their vehicles being destroyed. Those who manage to go to these areas therefore naturally hike the prices citing the risks they have to take in order to bring the commodities to the market. Matters are worsened by the fact that we are now in the dry season when scarcity of the various food commodities tends to push up the prices. We hope that the politicians will find a solution to the conflict and save the country from an all-out famine. Farmers go for organic manure Exorbitant fertilizer prices have forced farmers in the Rift valley to go for farmyard manure. The price of one bag of DAP fertilizer has shot up from Ksh 1700 to Ksh 3500 in the maize growing areas of Uasin Gishu and Trans-Nzoia districts. Most farmers are reportedly visiting Agricultural Development Corporation farms and other large-scale farms in Trans-Nzoia in search of farmyard manure for use in planting. This is after realising that they cannot be able to afford chemical fertilizers due to the high prices. Since we started The Organic Farmer magazine, we have always emphasised the need to use sustainable methods of production, first to reduce costs to the farmer and secondly, to help build soil fertility and increase yields. Chemical fertilizers can increase yields in the short term but they have an adverse effect on the soil when used for a long time. The use of compost on the other hand reduces soil acidity while increasing organic matter and releasing essential nutrients to the soil and in this way See pages 4, 5&6 (TOF) feeding the plants.

The Organic Farmer The current political crisis had farreaching implications on the overall food security situation in the country. According to the Ministry of Agriculture estimates, more than 3 million bags of maize were destroyed during the skirmishes in parts of Rift Valley province. This is quite a significant loss especially taking into account the fact that many of the affected farmers may not be able to go back to their land in time for the planting season, which is supposed to start this month. Food prices all over the country have gone up for various reasons, many of which have to do with the current crisis. The middlemen as usual, have taken advantage of the situation to hike prices and make hefty profits at the expense of the consumers, some of them citing increased transport costs and unavailability of supplies. Areas hit by the clashes are mainly the high potential food producing regions where most of the agricultural commodities are produced. This

For the last two months, farmers in some parts of the country have lost relatives, land, property and their livelihoods. We are deeply saddened by the fact that this has happened in Kenya which, in the past, has remained to be an island of peace in a region full of conflicts. We only hope that this animosity and hatred between various communities that broke out after the disputed elections can be brought to an end and people continue to live in peace and harmony as they did before. Of course, our big concern is agriculture. We strongly feel that it is time that we begin to rethink about the issue of land ownership. The government should have a clear policy on land which in the future will help reduce conflicts. Our only fear at this time is that the displaced people may not be resettled in time to begin preparing their land in readiness for the planting season which starts this month. The violence started just when most of the farmers were harvesting their crops. A lot of stored food was also destroyed since most the victims abandoned it as they fled their homes in fear of attacks. It is sad to imagine that farmers who were just preparing to harvest or sell their farm produce are are now threatened with famine. Our political leaders should resolve the post-election conflict so that farmers can resume their activities.

Kikuyu grass suitable for big farms Kikuyu grass controls soil erosion and can withstand heavy grazing. But it requires intensive management.

The Organic Farmer Kikuyu grass is common in many farming areas in the country. Most farmers rely on this grass to provide pasture for their animals. Kikuyu grass is palatable and easy to digest especially when young, a reason why animals like it (farmers are advised to feed their animals with some little hay after grazing on young kikuyu grass as it causes bloat). The grass does well in most climatic zones. Although it tolerates low fertility soils, it tends to grow better in fertile soils. However, overgrazing and poor management of this grass is evident in many farms. For good establishment as a pasture, Kikuyu grass requires intensive management. Unless by using specialised harvesters, it is difficult to harvest its seed for planting because its flowering stems are very short. Farmers are advised to use cuttings when they want to plant the grass. Research shows that dry matter and crude protein content in kikuyu grass is higher than that of Boma Rhodes The Organic Farmer is an independent magazine for the Kenya farming community. It promotes organic farming and supports discussions on all aspects of sustainable development. The Organic Farmer is published monthly by icipe and distributed free to farmers.

Kikuyu grass (Whittet), this is an improved variety popular with many farmers.

grass especially when the grass is eight weeks old. The grass is also an excellent source of riboflavin and provitamins in the animal diet. It helps to control soil erosion and can withstand heavy grazing. It can grow naturally even with little mineral supplementation. The right size is important Well managed Kikuyu grass can produce very good pasture for farmers. Many farmers make the mistake of grazing their animals on kikuyu grass before it has attained the right size. Pasture specialists recommend grazing when the grass has grown to an average of 4 to 5 leaves. Experienced dairy farmers in developed countries have been able to raise dry matter production of between 16 and 24 tonnes per hectare, especially when improved Kikuyu grass (whittet) is grown with other grasses such as rye grass. However under the local production systems where the land sizes are small, it is difficult to obtain this yield. Production of Kikuyu grass is more successful in commercial large-scale dairy farming systems where land is not a limitation. There are three major Kikuyu grass varieties in Kenya– Rongai, Molo, Kabete, Whittet and Breakwell: Rongai: The variety has rough, broad leaves and thick stems which develop rapidly after cutting. Molo: A finer grass with narrow leaves and more slender stems which produce shoots from the centre after cutting. Its pollen is sterile. Kabete: This is a medium size variety that has longer stamen that produces pollen.

(TOF)

Whittet: This is a taller and rougher variety. It has more broad leaves than the Kabete variety. It survives better than other varieties under less fertile conditions. The variety is becoming popular with local farmers as it produces more pasture compared to the other varieties. Kikuyu grass needs management Kikuyu grass does well under the following conditions: Rainfall requirements: In its natural habitat the grass requires 1000-1600 mm of rainfall either falling in one season or two seasons. Soil requirements: Kikuyu grass grows naturally in soils with good fertility, but it also adapts well to other soils such as alluvial or moist sandy soils which are fertilised with farmyard manure or even mineral fertilizers. Land preparation: A well-prepared seed-bed is necessary for good establishment where seeds are used. For stem and root cuttings, a rougher seed-bed is necessary. Sowing: Hand planting of vegetative stem and root cuttings is recommended. Cuttings containing two or three nodes planted at a spacing of 1 m are planted. When using seed, sowing at approximately 5 mm depth is ideal. The whittet variety can germinate at a depth of 6 cm.

Know about mastitis and how to control it Farmers should observe cleanliness udder of an infected cow. This form while milking to prevent their cows of mastitis is mainly caused by strepfrom getting infected with mastitis. tococcus agalactiae which is found in William Ayako Despite the progress that has been made in the Kenya’s dairy industry, mastitis remains one of the diseases of economic consequences to the Kenyan dairy farmer. Mastitis is an inflammation of udder caused by bacterial micro-organisms mainly of the streptococci and the staphylococci family, which are common in animals and their environment. The infection occurs when the micro-organisms gain access to the udder through the teat canal. The infections in the udder affect the quantity and quality of the secreted milk. The disease is known to cause economic losses of up to 40 % of the herd’s productivity. The disease occurs wherever dairy cows are bred, fed and managed for milk production. There are high chances of the occurrence of the disease, unless very strict control measures are continuously put in place. The animal is predisposed to the disease by several factors such as age, state of lactation, milk yield, hereditary factors, trauma and lack of hygiene. Clinical signs of mastitis There are 3 clinical forms of mastitis: Sub-clinical mastitis: This type can only be detected by a laboratory examination of milk drawn from the

the animal. Where production of milk is meant for export market, this form of mastitis is known to contribute to a bigger proportion of rejected milk. Mild-clinical mastitis: In this form of mastitis the animal shows distinct changes in the udder, sometimes detectable by palpation. The udder becomes firm to the touch in one or more quarters. The changes in milk are, however more definite. This form of mastitis can be examined using the black plate in the strip-cup. Milk can be seen to be of watery consistency and of abnormal colour, which often could be pinkish, or yellowish due to blood staining. Flakes or clots in milk can be noticed by the strip- cup test. Acute or severe clinical mastitis: The milk changes are more definite with the udder having typical inflamed signs. Such changes consist of yellow sediments at times with blood clots. The milk may also appear green or yellow-green and even with a foul smell especially when the infection is caused by the Corynebacterium pyogenes (pus forming bacteria). The udder is swollen and painful to touch. At a closer observation, the teats may reveal signs of injury. As the disease progresses, the udder becomes hard, the milk yield decreases and also becomes thin, watery or grey in color.

Measures farmers can take to control mastitis

Since mastitis is a management disease in a dairy farm, the disease can persist even with utmost hygiene in the farm. With this in mind, dairy farmers are advised to adhere to the following seven control measures. 1. Infected cows should be milked last. 2. Milkers should thoroughly wash their hands before and after milking each cow. 3. Hot water mixed with a dairy disinfectant should always be available in the dairy. 4. A separate clean udder cloth or a disposable tissue paper should be at hand for cleaning of the udder. 5. First streams of milk from each quarter of the udder used to test for mastitis should not be dropped on the floor but should be directed into a separate container with a dairy disinfectant.

6. Where machine milking is practiced, footbath with disinfectant should always be provided. 7. Normal milk room hygiene including washing of containers and equipment should be continuous. 8. Always change cow beddings to keep the udder clean. It is worthwhile for farmers to note that the most essential prerequisite for developing any control program is an accurate determination of the extent of the disease in the herd. A suitable control program can be achieved if farmers carefully and frequently use the tests described above. Furthermore, if the above control measures were followed by the farmers, the veterinary costs of treating the disease would be minimized.

Plant early and increase your harvest

Farmers should start practising crop making timely decisions on required rotation and adopt sustainable inputs. methods of production to increase One problem is that popular maize maize yields. seed varieties tend to be in short supply The Organic Farmer The planting season is a very important period for the farmer; any decision made at this time shall determine the amount of harvest a farmer will get at the end of the year. Timeliness in planting is a very important aspect of farming. Any delays in planting can cause great losses in both yield and income. One of the causes of delayed planting is lack of early preparation – early planting therefore calls for proper planning. Planning involves

during the planting season which may force farmers to go for varieties that are not suitable for their agricultural zones. The sale of expired maize seeds is also a common malpractice in the seed market at the time of planting. Some seed stockists sell expired maize seeds! Unless stored in a cool and dry facility, maize seed exposed to sunlight for a long period becomes weak and cannot grow well. This can be avoided if farmers are able to plan and buy seeds early enough. The first rains often start in mid-

Reduce use of chemical fertilizers

One the biggest problems facing farmers in the country is the declining soil fertility. Maize as a crop is a heavy feeder; it takes away a lot of minerals and nutrients from the soil. Farmers who have planted maize in the same field for the last 20 or more years is a common occurrence these days. To increase their yields therefore, they are forced to use more fertilizer. As they use more fertilizers, soil acidity increases. The eventual result of this practice is that whatever amount of fertilizer or seed variety the farmer may use, the yield cannot increase. The use of chemical fertilizers such as DAP is to blame for this problem. Too much acid causes available nutrients to dissolve too fast while too little acid may reduce nutrient intake by plants. The amount of acidity is measured on a mathematical scale called pH. The highest acidity level in soil has a pH of 1. The highest alkaline level in the soil has a pH of 14. At pH 7, the soil is said to be neutral. Most healthy soils have a pH of between 5.5 and 7.5. A good uptake of minerals and other

essential nutrients can only take place within this neutral range of acidity and alkalinity. Any serious farmer should be able to know the pH level of their soil before planting any crop; to know the state of their soils, farmers can take several soil samples from different parts of the farm and have the soil tested at an agricultural research station near them. Some agricultural extension personnel have access to pH metres which can test the soil and give instant results. Another way in which farmers can improve the condition of their soils, is by ensuring continuous use of organic manures. Every year, the farmer should incorporate crop residue back into the soil instead of burning it as is the practise with most farmers. Soil fertility can be replenished by application of well-composited farmyard manure at the rate of 4 tonnes per acre (8 tonnes/ha). Planting a different crop in the same field every year will not only reduce the problem of pests and diseases but will also help build soil fertility and increase your maize yield in subsequent years. (TOF)

March, at this time farmers should be ready for planting. Any delay in planting will lead to reduced yields. Maize planted after the onset of the rains cannot germinate well because the soil temperatures tend to go down as the rainfall increases. Dry planting (planting when the rains have not started) is especially advisable because germination tends to be vigorous. Researchers have proved that a farmer loses an average of 2 ½ bags of maize per acre every week if they plant after the rains have started. Maize planted early also benefits from nitrogen flash- this is a process where the new maize plants are able to utilise nitrogen in the soil before it is lost through leaching when the rains come. Farmers should also observe the following guidelines to increase their maize yield. Land preparation Hand digging is particularly recommended in small-holder farms because it does not disturb the soil much. Tractor ploughing compacts the soil, reducing air circulation and killing important soil organisms that help promote plant growth. Seeds Some farmers use farm stored maize as seed, but this is wrong because hybrid seed cannot be re-planted; for hybrid seed, the farmer has to buy new seeds every year. Spacing Most farmers plant their maize very closely in the belief that when the maize is crowded, the yield will be higher. When the plants are crowded, growth is poor because the seedlings compete for sunlight, water and nutrients thus becoming weak. The correct spacing should be 60 cm (2 ft) between one hole and the next. Spacing between rows should be 75 cm (2 ½ ft). It is important to plant only two seeds per hole.


Let us fight malaria

The Organic Farmer Nr. 34, March 2008

Malaria Special

Malaria prevention is cheaper than cure Malaria is one of the major disease burdens worldwide. It causes about 400-900 million cases of fever and approximately one to three million deaths annually. More than 90 percent of illnesses and deaths due to malaria occur in Sub-Saharan Africa. Children and pregnant women are at a higher risk. In Kenya, it threatens the life of around 25 million out of the country’s total population of 39 million people. Malaria is estimated to cause more than 20 percent of all deaths in children under the age of 5 years. Every Kenyan family spends an average of Ksh 1,400 every year to treat cases of malaria. Malaria is caused by protozoan parasites of the genus Plasmodium, which are transmitted by the female anopheles mosquitoes. A mosquito becomes infected when it sucks blood from an infected human being. The mosquito then carries the infectious Plasmodium sporozoites in its salivary gland and spreads the disease by biting other humans. Blood test important Early diagnosis and prompt treatment are key elements of malaria control because they can shorten the duration of the infection and prevent further complications including most deaths. Whether someone has malaria or not can only be determined by a blood test. Since malaria symptoms can

Dear Farmers, Every day, 3,000 children in Africa die from malaria. In Kenya alone, 62 children below 5 years succumb to this scourge daily. This is unacceptable! When affected, the patient cannot work, children cannot attend school and farmers cannot tend their farms. Apart from the grief due to loss of their loved ones that malaria causes in many families, it reduces the quality of our day-to-day-life. Moreover, we should not forget the socio-economic impact. Malaria is not just a disease commonly associated with poverty, but is also a major hindrance to economic development. The impact of malaria on the economy has been estimated to cost Africa Ksh 720 billion every year. This includes the costs of health care, working days lost due to illness, days lost in education, decreased productivity due to brain damage by cerebral malaria, loss of investment and decline in tourism.

be very similar to those of a severe flu – notably fever, shivering and headaches – it is important to confirm the infection of malaria through a proper diagnosis before taking any drugs! If any drugs need to be taken, the prescribed dosage should be followed timely and accurately. Correct usage of anti malarial drugs is an important means to prevent the malaria the last 5 years, the Kenyan Ministry parasite from developing resistance to of Health has distributed 13.4 million mosquito-nets.

Do not forget: Prevention of malaria is by far much more cost-effective than the treatment of the disease! However, the fight against malaria can only be more effective if we thoroughly know about the behaviour of the mosquitoes and the way they transmit the disease. We have to know the prevention methods. This is why The Organic Farmer brings you this special issue.

Know your enemy - to be able to fight him Many people are infected by malaria not only because of ignorance but also due to negligence. Therefore the first step towards avoiding the disease is to understand the mosquito’s life cycle. Just imagine, a single mosquito can deposit 80 to 200 eggs during its life span, which can take up to a month! Being very smart, anopheles mosquitoes have adjusted perfectly to their host; since many people are now using bednets, the mosquitoes have also

changed their feeding habits. Previously they would begin biting between 9 and 10 pm when most people went to bed. Now they begin to feed earlier before people retire to bed. However, bednets still provide the most effective protection against mosquitoes. The second step is to act: To avoid mosquito bites, we have to combine all the possible measures to protect ourselves.

The life cycle of an anopheles mosquito 1

This illustration teaches us two things: - We should drain away all stagnant water (page 3). - Use mosquito-nets during the night (page 4).

Other methods of malaria prevention Indoor spraying: This is the most effective means of rapidly reducing mosquito density. Its full potential is reached when at least 80 per cent of the premises containing mosquitoes are sprayed. It is effective for 3 to 6 months, depending on the insecticide used and the type of surface on which it is sprayed. The most common insecticide for spraying indoor walls is called ICON. The application has to be repeated every 6 months. ICON is quite expensive. Naturub: This balsam and remedy balm is produced from extract of the Ocimum suave plant leaves. Naturub, the result of a promising project (done by ICIPE-researchers, and financed by BioVision) is a strong mosquito repellent. Neem oil: The oil of the neem seeds is an old mosquito repellant. It is availabe in all pharmacies and chemists (see also page 4) Mosquito coils: These are available in most shops (a pack of 10 coils goes for Ksh 25). Secure the coil in its holder and place it on the floor where you spend the evening or night. If you are sitting around a table, put the coil under the table, this will drive away mosquitoes since they prefer dark sites located near the floor to bite. The fume of the coils should be positioned in such a way that it swathes

the legs, since anopheles mosquitos are attracted by smell of feet! Smoking: Insects don’t like smoke; smoke from the fire place will chase the mosquitoes away. To repel mosquitoes, one can use animal dung. A more effective method (and with a better scent!) is the smoke of the leaves of eucalyptus trees and of neem trees. This smoke gives more than 70 percent protection. Bacillus thuringensis (Bt): Even more promising are trials with bacillus thuringensis. This bacillus, thrown in stagnant water, kills the larvae, but does not harm fishes or human beings. Two types of bacillus thuringensis are being used successfully in western countries to control mosquitoes in nature reserves. These biological control agents are very expensive and are not available in the African market. Sawdust of neem trees: ICIPE-researchers in western Kenya experimented with cushions filled with neem tree sawdust. The cushions were thrown in stagant

water (such as bricks-ponds); the neem killed the larvae. Research is still on going, but the results are promising.

The tiny larvae start to feed on algae and bacteria present in the water. The larvae (about half a centimetre long) are well visible by eye.

The problem with DDT One of the most controversial insecticides is DDT. Developed as the first of the modern insecticides, DDT was extensively used in the 1950’s and 1960’s during the malaria eradication campaign. The problems began when DDT was used more and more and in huge amounts in agriculture to eliminate insect pests, particularly in the developed world. In the 1970’s, DDT was banned because of its damaging side effects to humans, wildlife and the environment. By this time, its large-scale use had already led to the evolution of resistant mosquitoes in many regions where it was extensively used. There is considerable controversy regarding the restrictions placed on the use of DDT in controlling malaria. Some African countries would like to lift the ban on the use of DDT to control insects. Most of the problems associated with DDT use stem specifically from its industrial-scale application in agriculture, rather than from its use in public health to eradicate malaria. However, in the long term the use of DDT is more harmful than beneficial.

No stagnant water – no mosquitoes – no malaria

Water is precious, essential for human well-being, for the household, for your livestock and for your crop. Water is at the same time the breeding ground for the eggs of the anopheles mosquito. This means that the management of your water has to take into account the need for the prevention of the transmisson of malaria. Do not give the mosquitoes a chance to find water in which to deposit

their eggs. Water that flows freely does not usually harbour mosquito eggs. All measures to reduce the opportunity for mosquitoes to deposit their eggs in stagnant waters should be taken together by neighbours and the entire community since mosquitoes do not respect shamba boundaries! The smallest puddle can be infested by these dangerous insects.

1. Use covers: The containers used for the storage of drinking water must be covered at all time either with a net or a lid (plastic tanks should be covered at all time with the screw cap). 2. Remove any stagnant water: Rain water is usually collected in flower pots, used tyres, tin cans, thrown away plastic bags, wreck-

ages of cars, tractors and agricultural machinery. Remove them! Manholes and unused wells should be covered tightly to prevent mosquitoes from laying their eggs in the water. 3. No puddles! If you irrigate your crops, do it with the required amount of water. No puddles should remain standing after irrigation. Think about drip irrigation: With this method the water drips slowly into the ground without leaving any standing water. With drip irrigation, you use much less water!

Let the water flow since mosquitoes do not breed in flowing water! Keep your irrigation trenches open, so that the water is able to flow freely. Prevent the formation of cavities (notches which hold stagnant water in the trench), remove the grass and any rubbish that may have accumulated. Use irrigation pipes if possible.

Water points and ponds for your livestock are difficult to be kept free of mosquitoes. In ponds, the presence of fish is of course ideal. You can eat fish, and a single fish can devour hundreds of mosquito larvae every day. It is recommended that you contact the fisheries department for advice on larvae-eating fish.

Protect your family with a mosquito-net

The main biting period of anopheles mosquitoes lasts from sunset to sunrise. Therefore, everybody should sleep under a mosquito-net. The nets keep mosquitoes away from people, and thus greatly reduce the risk of transmission of and infection with malaria parasites. Nets impregnated with insecticide are a highly effective means of malaria prevention. Furthermore, it is also one of the most cost-effective methods. Insecticide-treated nets have the advantage of protecting people sleeping under the net and simultaneously killing mosquitoes that come into contact with the net. Nets, which are treated with insecticides, are estimated to be twice as effective compared to untreated nets and thus offer a markedly improved protection. Damaged nets are dangerous, allowing access of mosquitoes to the sleeping area. Therefore, check your nets every day, and if you find holes, mend them immediately. Two types of Insecticide-Treated Nets: • The Insecticide Treated Nets (ITN’s) are standard nets, which you have to treat yourself. To do so, use Powertab tablets as follows: dissolve 1 tablet in 0.5 litre water and soak the net for 1 min; protection lasts for 15 washes of the net, 1 tablet costs Ksh 40. • The Long-Lasting Insecticide Treated Nets (LLITN’s) provide good protection, especially to risk groups like young children and pregnant mothers. The nets are effective for 3 – 5 years, depending on models and conditions of use. Afterwards you can treat them with PowRepair your nets! ertab tablets.

In addition, the organisation Population Services International (PSI) distributes nets through rural commercial outlets throughout the country at a cost of Ksh 100 each, to fit a double-size bed. The organization also sells Long-Lasting Insecticide Treated Nets at a cost of Ksh 50 per net through health facilities of the Ministry of Health countrywide. Because of the high subsidy, these nets are only sold to pregnant women and children below 5 years.

Recommended anti-malarial drugs Before you take drugs, make sure that you confirm the infection of malaria by a blood test to avoid resistance! Once an antimalarial drug is prescribed, it is essential to follow the prescribed dosage. There are several families of drugs used to treat malaria. Chloroquin is very cheap and, until recently, was very effective. However, the anopheles mosquitoes developed resistance, making the drug ineffective against the most dangerous plasmodium strain. Since 2001, the World Health Organization has recommended the use of Artemisinin-based Combination Therapy (ACT) as first-line treatment for uncomplicated malaria in areas experiencing resistance to older medications. Extracts of the plant artemisia offer over 90% efficacy rates, but their supply is far below the demand. Because ACT’s cost up to twenty times as much as previously used medications, they remain unafford-

able in many malaria-endemic countries. Coartem is a drug, which is recommended by the World Health Organisation and a combination of Artemether and Lumefantrine (AL). It is distributed for free at public and mission health centres. It costs Ksh 400 - 650 if bought over the counter. Coarsucam (6 tablets), at a cost of about Ksh 500 ( recommended by pharmacists for patients in Western Province) Cotexcin (8 tablets), available at about Ksh 400 (for patients in Coast Province).

Conservation agriculture protects the soil Farmers have concentrated more on food production and forgotten to take care of the soils. Minimum tillage restores soil fertility. The Organic Farmer Farming as practiced by many local farmers is very destructive to the soils. Farmers rarely use sustainable methods of soil cultivation that can protect its structure and fertility. If they cared to look after the soils, they would not only be able to increase production but also they would improve on their income. Rapid population growth has forced many farmers to over-cultivate land. They have consequently abandoned traditional methods of land cultivation that helped to protect the soil. Careful soil cultivation can improve its capacity to retain water, allow movement of air (aeration), infiltration, warming up and even minimize evaporation. Soil over-cultivation can harm soil fertility as it accelerates soil erosion and the decomposition of humus. Any soil cultivation activity has one or more destructive effect on the soil structure. In Africa and other tropical countries, regular ploughing has accelerated the decomposition of organic matter which has led to tremendous nutrient loss. The mixing of soil layers through tractor ploughing can severely harm some soil organisms. After ploughing, uncovered soil is prone to erosion when it rains heavily. It can save costs Minimum tillage systems help to build up natural soil structures with a crumbly top soil rich in organic matter and full of soil organisms. Nutrient losses are reduced to a minimum as there is no sudden decomposition of organic matter. If the soil is not disturbed much, nutrients in the soil are retained by a dense network of plant roots. In such a case soil erosion cannot be a problem because there is a permanent plant cover and enough organic matter. In addition to this the farmer also saves on labour costs which they cannot afford. Maintain the soil structure Conservation agriculture (or minimum tillage) has three basic principles: Maintaining the soil structure through minimum tillage (land preparation), keeping the soil covered as much as possible and practising crop rotation. The main aim of encouraging conser-

vation agriculture is to ensure that the farmer gets a high crop yield while at the same time maintaining soil fertility and also conserving water. In conventional farming, farmers plough or use hoes to improve the soil structure and control weeds. By ploughing, they actually destroy the soil structure and contribute to soil infertility. In conservation agriculture, ripping the soil to make planting lines is practiced. Ripping helps break the hard pan which forms on the top soil when the soil is compacted. Alternatively, holes are dug into the soils and the seeds planted. The idea is to plant directly into the soil without ploughing it. Provide soil cover In conventional farming, farmers remove or burn the crop residues such as maize stocks and bean residue or incorporate them into the soil with a plough or a hoe leaving the soil bare. When it rains therefore, all the top soil is washed away by rain or blown away by wind during the dry season. Farmers who practise conservation agriculture leave crop residue in the field. The residue is used for mulching to cover the soil to prevent

soil and wind erosion. Farmers who practice conservation agriculture also plant cover crops to protect the soil from erosion and limit the growth of weeds throughout the year. Practise crop rotation In conventional farming, the same crop is sometimes planted each season on the same piece of land. This practice allows certain pests, diseases and weeds to survive and multiply, resulting in lower crop yields. In conservation agriculture, farmers choose various crops that are planted in the same field but rotated from season to season, a practice that helps maintain soil fertility. To gain the full benefits of conservation agriculture, the three principles discussed here above have to be applied at the same time. Practising conservation agriculture can be a challenge for a farmer who is not used to it, but it is important to change the way farmers have practised farming before in order to increase their yields and income. For example, many farmers are used to clearing their land of all the residue and leaving it “clean” but they do not know that they are denying their soil essential organic matter that can help enrich it. By switching to conservation farming, farmers may save on labour, reduce costs, improve their soils’ fertility and ability to hold water. Minimum tillage can enable them get higher crop yields and income. The time and resources saved by adopting this sustainable farming method can be used to cultivate more land or even start other enterprises to diversify their sources of income.

Tips on minimum tillage •If there are crop residues near your shamba, carry them to your field and spread them on the soil surface as mulch. •Plant a cover crop during the first season. Choose a cover crop such as lablab which has deep roots to improve soil fertility and structure. A cover crop can be grown on a separate field then cut and spread on the soil at the beginning of the second season. The cover crop can give you seeds for your future use and can also be sold to your neighbours. At harvest, leave the crop residue in the field to cover the soil during the dry season; this helps retain soil moisture.

Food prices increasing worldwide

As global food prices continue to soar to new highs despite a record world harvest last season, governments in poor countries have begun exploring export bans, subsidies and price controls, among other measures to help the poor cope. High food prices have been triggered by various factors, including dwindling stocks and a continuing strong demand for cereals, according to the latest Crop Prospects and Food Situation report by the Food and Agriculture Organisation (FAO). International wheat prices in January 2008 were 83 percent higher than a year earlier, said Liliana Balbi, senior economist at FAO. According to the FAO, there a several factors behind the crisis: More intense weather events as result of climate change, the global economic crisis, fuel prices and the pressures brought on by biofuel. This is fuel produced from sugarcane, maize, wheat and a variety of other crops. Example of Swaziland Forty percent of the population of Swaziland is in acute danger of starvation. A long dry period has led to one of the poorest maize harvests ever. At the same time, the Government of Swaziland has decided to make land available to a private enterprise to cultivate cassava for biofuel production. This example clearly illustrates the dilemma faced by many developing countries in their struggle to achieve food security for their populations. (FAO)

Resolve the land issue immediately

The problem of land is at the heart of current unrest in parts of the country. Despite the efforts by successive governments to sweep the matter under the carpet, it keeps recurring every time we have elections. Since independence, successive governments have not solved the problem of landlessness. They wish it would just go away. The Kenyatta and Moi regimes did little to resolve the problem; during their time in power, land was dished out to favoured groups which supported their stay in power. Thousands of Kenyans remain landless with no hope of ever owning a small

We are all Kenyans

I feel very sorry for fellow Kenyans who have been declared “foreigners” and thrown out of their land. Some of the victims of the current violence are the second generation of land owners who were born in those areas; they even talk the local language and do not even know the so called ancenstral lands. After 40 years of independence, why should we call fellow Kenyans “foreigners’ in their own country? I think something must be very wrong with our society. We badly need to re-examine ourselves and stop the country from self-destruction. George Kegoro, Nyamira

parcel of land they can call their own; at the same time, well-connected people who walked the corridors of power now own thousands of acres which lie unused. Nobody talks about these issues; instead people’s anger is being directed at fellow poor people who happen to come from particular communities. Killing our fellow poor Kenyans and burning their houses will not solve the problem. It is time all of us came together to explore the root cause of the problems we face. We cannot do this when we are fighting. Mike Kibowen, Moiben

The best way to plant tomatoes What are the right measurements for planting tomatoes? Carl J. Michael, Kapenguria. The right spacing for planting tomatoes depends on the type of tomatoes being grown. There are three types of tomatoes, determinate, semi-determinate and indeterminate. Determinate varieties This type of plants grow to about 3 feet high and produce medium size fruit. They are easy to manage and thus can be grown slightly closer together. They are still best staked (mostly salad types) to avoid touching the ground and also to allow good aeration. These can be spaced at 2.5 feet. The fruits on determinate plants all ripen around the same time. In this category we also have the cal J types that are more hardy and do not require staking. These tomatoes are mainly for processing and grow best on a bedding of dry mulching. They usually do better with wider transplant spacing, of approximately 3 feet. Indeterminate types If tomatoes are of the indeterminate type, they will continue to grow up to a height of more than 7 feet. This type needs to be supported and grown on stakes or up vines, strings or fences. They are also quite difficult to desucker. The best way to grow them is to form a structure and frame using poles above the plants. As the plants grow, you should support them with strings. The harvest of fruits should be from the lower trusses first as indeterminate tomatoes ripen up the plant stem at different stages. As this is done, the lower leaves and trusses can be removed and the supporting string lowered allowing the tomato main stem to form a coil on the ground. This allows you to manage your plants w i t h o u t having to try harvesting them on a ladder. Due to the vigorous growth of this type of tomatoes, it is advisable that they have good, wide spacing. Spacing of 3.5 feet is suitable. This spacing also

allows for better aeration and less humidity build up, which discourage pest and fungal diseases. Semi-determinate varieties. As the name implies, these varieties are taller than the determinate type and not as tall as the indeterminate variety. Their spacing is best done at around 3 feet. It is important to remember that tomatoes are very fragile and extremely difficult to grow organically. Thus, all precautions necessary must be taken to avoid loss of crop. Spacing at transplant is very important. Know your variety well before planting. In my experience, some of the hardiest tomatoes are the little cherry variety that grows wild around most homesteads. These plants seem to be fairly resistant to many problems that affect our hybrids. In my recent visit to Switzerland, I was very impressed to see extremely successful tomatoes being grown in a green house half way up the mountains! It apparently became clear that the differences between the very cold winter and warm summer allow for the total eradication of pests and disease. They cannot affect consequent plantings. We in Africa do not have such big weather differences. Here, pest and disease cycles are continuous in many areas. Su Kahumbu

Tamarillo

What is the right spacing, economic span and productivity per tree of tree tomato or tamarillo? Anne, Nanyuki, 0725 210’160 It depends on soil fertility and the location of your farm. The trees are planted 2.5-3 m apart in paired rows 2.5 m apart with 4.25 m between each pair. If the soil is very rich, a spacing of 2.75 m is allowed between the rows and 5 m between the pairs. Closer planting is recommended in windy, unprotected locations, for instance 1.51.8 m between the plants and 2.5-3 m between the rows. The trees may be staked to prevent swaying and disturbing the roots. The tree usually begins to bear fruits when 1 ½ to 2 years old and continues to be productive for 5 to 6 years. If it is adequately nourished, it may keep on fruiting for 11 to 12 years. On average, each tree is expected to yield 15-20 of fruit annually. TOF
