Sustainable Use of Biochar, Poultry and Cattle Manure for the Production of Organic Granular Fertilizers

In agricultural activities, there is an increasing need for organic fertilizers to use nature-friendly materials used fertilize the soil. Farmers have been using granular made from composted or dried manure of cattle, poultry, pigs, ash, bone meal, and other some time, but quantities these are not large. Biochar also being intensively studied as a material improve soil quality plant growth reduce greenhouse gas emissions The suitability cattle compost, poultry manure, biochar, their combinations was analyzed in this work. preparation biochar granulation may differences compared due moisture content, fractional composition, bulk density, parameters granulated material, so work examines physical–mechanical chemical properties raw final product. Research has found that composition under investigation up 2 mm. content varied 8.97% case 25.11% compost. lowest obtained additional drying. addition reduces granule density investigated cases. Poultry granules were most mechanically stable, with semi-static stability 382.6 ± 78.08 N. After weaker binding determined experimental granules. Analysis elements shows can be fertilization improvement. High concentrations nitrogen (N), phosphorus (P), potassium (K) detected results showed it appropriate enrich biochar.
