Researchers Daiane Hyeda, Ariane de Paula and Lucia Helena Wiecheteck, as well as the support of researcher Alisson Fogaça the EMBRAPA forest team, collected micro-organisms in the soil. In the research process, they evaluate the effect of biochar on soil microorganisms. Thanks to its collections, it is possible to evaluate the influence of biochar on microbial activity. Initial data could already be presented at the 16th Biological Nitrogen Binding Symposium in non-legumes held in August in the city of Foz do Iguaçu, where researcher MS Daiane Hyeda presented the work done in the experimental field. Esperança farm, at which there was an increase of enzymeurase activity.
In general, the presence of biochar generated higher urease activity, indicating that more NH3 was produced. Thus, there is no more availability of N for eucalyptus plants in this condition. It can be indicative of soil quality and fertility, since its presence indicates good soil management, as well as variations in nutrient availability.
