Nitrogen of Stemma Slow N is available for a long time thanks to its gradual release from polymeric chains of small molecular weight.

The presence of important trace elements like boron and zinc provides excellent action on fruits trees nourishing buds in post harvest applications.

RATE OF USE

Foliar:

Fruit trees (after harvest) 4-6 l/ha - Industrial crops and cereals: 5-10 l/ha - Fodder crops: 10-15 l/ha

THE POTASSIUM-SULPHUR COMBO FOR THE BEST RIPENING

Stemma SK HD guarantees the maximum bioavailability of Sulphur and Potassium. It is particularly suitable for applications in fertigation, even with hard waters and in alkaline soils.

Stemma SK HD anticipates and uniforms ripening, increases the sugar content, color and soluble solids

RATE OF USE

Foliar: for all the crops 2 - 3 l/ha

Fertigation: for all the crops 20 - 25 l/ha

A BALANCED VEGETATIVE PUSH

Tilstem HD (High Density) is a special fertilizer which allows for the simultaneous application of calcium and magnesium in the most natural balance for the crops, namely 2:1, together with nitric nitrogen. The high purity of the nutritional elements present in the formula allows to obtain, a quick action.

Tilstem HD grants also an effective recovery from water imbalance and it is mixable with the most common agrochemicals. Further, the product has a healing action on microlesions due to water excesses or hailstorms and improves the resistance of the fruits during transportation operations.

RATE OF USE

Foliar: All the fruits trees, vegetables and ornamentals 2-3 l/hl

ACTIVE ORGANIC MATTER FOR THE SOIL

Product suitable for use in Organic Agriculture conforming to regulations (EU) n° 2018/848 and 2021/1165 and NOP

Inspected by ECOCERT F – 32600

Vegorn is an organic fluid fertilizer containing an active mix of 100% vegetal matrices with polysaccharides selected for granting:

• a high combined concentration of nitrogen and potassium in organic form

• a peculiar richness in aminoacids (10 %) and glycine betaine ( 7%) which play an important role in overcoming stresses.

Applied to the soil, it activates the microflora, improves the physical structure of the soil and the absorption of elements, preserves the organic matter content of the soil and reduces the negative effect of all the abiotic stresses and of salinity.

RATE OF USE

Foliar: All the crops 3-5 l/ha

Fertigation: All the crops 10-20 l/ha

ACID WATER-SOLUBLE FERTILIZER WITH CALCIUM

Calstem is a line of fertilizers formulated in water-soluble powder with acid reaction. Calstem is distinguished from any other water-soluble NPK fertilizers because in addition to nitrogen, phosphorus, potassium and microelements. It also provides an important amount of assimilable calcium, not easy to integrate in an acid fertilizers.

The considerable acidity of Calstem fertilizers pH 3.0 ± 0.5 improves solubilization and availability of the mineral elements. They also help to keep the fertigation systems clean, avoiding insolubilization and precipitation of the mineral elements.

Green Has Italia has created this specific line of water soluble NPK to fully and effectively feed crops throughout the production cycle, by providing the necessary fertilizing elements at each stage. Using a single product.

This allows to simplify the fertigation process, employing the minimum the number of products.

NPK WATER SOLUBLE FOLIAR FERTILIZERS WITH MAXIMUM ABSORBTION AND QUICK AVAILABILITY

Stemma Leaf is a range of water-soluble microcrystalline foliar fertilizers, deriving from selected raw materials of the highest quality and purity, free from sodium, chlorides, carbonates and other insoluble or toxic substances.

Stemma Leaf formulas are tailored for foliar spraying and they are easily absorbed by plants: they nourish plants, meeting their precise needs during the entire crop cycle for maximum yields and top quality.

Moreover, every formula contains a high concentration of micronutrients in form of EDTA chelates that integrates the nutritional uptake and increases products effectiveness.

The full solubility allows for easy tank mixing and eliminates any risk of spray and blockage.

FOR AN EFFECTIVE AND COMPLETE MINERAL FERTIGATION

Stemma NPK is a product line composed by water-soluble microcrystalline fertilizers developed with highquality substances, free from sodium, chlorides, carbonates and other insoluble or toxic substances. To fulfill all the crops requirements during the different phenological stages.

Multiple formulations are enriched with magnesium and micronutrients to sustain the nutritional intake and increase the efficacy of the product.

ACID NPK WITH MAGNESIUM AND MICRONUTRIENTS

Stemma VIP is a line of NPK fertilizers characterized by a low pH, which allows for the gain of acid nutritional elements and reduces the chance of obstructions of the irrigation systems.

Stemma VIP line contributes to the reduction of the bicarbonates present in irrigation waters, allowing for the use of our formulas even in hard and alkaline-pH waters.

This product line is characterized by the absence of carbonates and other substances that are insoluble or dangerous for plants.
