USE OF CHICKEN MANURE FERTILIZER FOR GROWING ORGANIC PRODUCTS

Abstract

This article explores the possibility and effectiveness of using chicken manure as an organic fertilizer “Soil Improver (UP-1)”, obtained by using the drug “Mephosphon” for growing crops and producing organic products. Under laboratory conditions, experiments on the fermentation of manure were carried out, measurements of the ammonium ion were carried out, and the levels of toxicity of extracts from chicken manure were studied using test objects Ceriodaphnia affinis and Paramecium caudatum, followed by determining the hazard class of chicken manure. Field tests were carried out on soddy-podzolic medium loamy soils of the Pestrechinsky district near the village. Khodyashevo. The total sowing area was 72 ha (1 ha - background, 19 ha - control, 52 ha - experimental field). The background field was without chicken manure, the control field was composted chicken manure, and the experimental field was with UP-1 fertilizer. 130 tons of chicken manure were applied per 1 ha. Organic compost “Soil Improver (UP-1)” was obtained from poultry wastes of OJSC “Agrofirm “Ak Bars – Pestretsy” branch of poultry farm of Pestrechinsky district of the Republic of Tatarstan. Biometric analysis of the growth and development of winter wheat was carried out from April 29 to June 1, 2021. The stem height of plants in the experimental variant is 14% higher than in the background, and 6.8 - 8.9% higher than in the control variant. According to the average weight of the raw and dry stem, the experimental group has the advantage, while surpassing the control in all periods of the growing season by 0.1-2.9 pieces. and 0.1-1.4 pcs. The obtained experimental data show that the use of organic compost “Soil Improver (UP-1)” as a fertilizer in the cultivation of winter wheat provides a higher yield compared to the background by 56.6%, and compared to the control by 55.5% . At the same time, 146.64 tons of organic winter wheat were obtained
