This article is devoted to the study of biotechnological methods of poultry waste processing and the influence of organic fertilizers on the growth of field maple (Acer Campestre). Biotechnology plays an essential role in organic waste processing which in turn helps to transform poultry droppings into environmentally friendly fertilizers that can significantly improve soil fertility and yields. Currently, no more than 20% of poultry manure is used as fertilizers in Uzbekistan. The use of poultry droppings at poultry farms in Uzbekistan has been poorly addressed today. Poultry manure is discarded outside the poultry farms, where it is either filled with pits not suitable for storage or unloaded in a specially designated area. Afterwards, it is not used and causes tremendous damage to the environment. At the same time, bird droppings contain high macro and microelements which form the core value as organic fertilizers. Physicochemical analysis has shown that the fertilizer contains 70% moisture, 17.3% ash content, pH 6.7, 1.9% N, 2.10% P₂O5, 0.93% K₂O.
