Prospects for application of organic fertilizer from bird litter

Abstract

Currently, the most effective way to dispose of bird droppings is to process it into organic fertilizer. The processed litter contains the basic micro and macro elements and amino acids in an easily accessible form for plants. Fertilizer from recycled litter is environmentally friendly and effective in neutralizing pathogenic microflora, larvae and helminth eggs, as well as weed seeds. In this work, we studied the modes of processing chicken manure at the Ark plant, the chemical composition of bird manure and organic fertilizer from it obtained in different ways. The effect of various doses of powder on seed germination, plant growth and development was assessed. It is shown that processing of bird droppings into powder increases the content of available macrocells for plants by two times, and also contributes to their longer preservation in organic fertilizer. The study indicates that pre-sowing soil treatment with powder in the optimal dose increases the germination rate of plants by 75 % compared with the control group.
