This paper will describe the methods that are used at the enterprise to obtain organic feed from poultry waste. These include conventional composting, vermicomposting, vermicelli production and closed chamber composting. The results of analyzes for the content of the following chemical components in the samples under study will be presented: phosphorus, potassium, organic matter (humus), nitrogen in nitrate and ammonia forms, bound nitrogen, as well as heavy metals and residues of pesticides and antibiotics. Based on the data obtained, a conclusion will be drawn about the advantages and disadvantages of each of the methods for obtaining organic fertilizers. |
