Ash for soil liming

ASH FOR SOIL LIMING – 55

The biomass burning process generates ashes, which are mineral materials that are not part of the burning, and are not useful for companies in the forestry sector. The aim of this study was to characterize the ash produced by a biomass boiler in a period of one year and, at the same time, evaluate the use of this material as an input for the production of eucalyptus seedlings in the field and wheat seedlings in the laboratory. The work was divided into three chapters where the first one characterizes the ashes of a boiler over a period of one year, considering the different materials that are inserted. It was concluded that the ash has homogeneous characteristics regardless of origin or origin. The results showed that the addition of ash at lower dosages enabled better wheat development, and the presence of biochar affected germination and productivity. Eucalyptus growth was evaluated by replacing conventional liming by adding boiler ash to the soil. It was possible to verify the use of ashes from biomass boiler in the soil liming process for eucalyptus development. Thus, the results of the work showed the

feasibility of using biomass boiler residues in companies in the forest sector, enabling the application of the concept of multiple uses of planted forests. However, on the other hand, I mentioned earlier that the ash can be used to partially replace the cement used in civil construction, if the ash is used in this sector, there will be a lack of ash to be used in soil treatment, causing farmers to buy fertilizers. and so spend much more, so there is a difficulty in inserting the ashes as something correct to be used in civil construction.
