Bezdil R. Agroecological substantiation of fertilizer application derived from rabbit waste.

The results of the study proved scientifically and practically environmental feasibility and effectiveness of applying organic and mineral fertilizers from rabbit waste in agrocenoses of zea mays under conditions of Right-Bank Forest-Steppe. It provides increase in agrocenosis biological productivity and improving product quality. Methods of processing organic rabbit waste into organic fertilizers by vermiculture are developed. The optimal composition and the ratio of substrate components for E. foetida worms are determined. Agrochemical characteristics of vermicompost obtained from rabbit waste and other agricultural residues is defined. The results of studies on the impact of vermicompost, organic and mineral fertilizers on their basis on the corn yield and quality are given. It is found that the application of vermicompost extract for lawns of phytocenosis crops increases the yield of perennial ryegrass and reduces inhibition of herbaceous plants by NaCl solution. This allows getting herbage of high quality with projective cover to 100%. The optimal doses of applying vermicompost are determined to get fertile soils from artificially contaminated by NaCl urban soils.
