The aim of the research was to study the effect of fresh chicken droppings on the dynamics of the physical-chemical and agrochemical properties of sod-podzolic soil and the yield of grain crops. In the sod-podzolic light loamy soil of the Yaroslavl region in the layer of 0-0.20 m in May, fresh chicken droppings were embedded at the dose of 120 t/ha. By autumn, in the 0-0.40 m layer of pH K c 1 increased from 4.53-4.99 to 5.38-7.09, the content of mobile phosphorus and exchangeable potassium increased by 2.0-2.4 times, nitrate and ammonium nitrogen - 3-5 times. The content of nitrates in the soil has exceeded the Maximum Allowable Concentration level. The grain yield of the spring wheat studied varieties, triticale and barley varied from 6.7 to 9.5 t/ha, chaffy oats - from 5.7 to 5.9, hulless oats - from 4.4 to 4.6 t/ha. At the beginning of the growing season of crops in the 0-0.40 m layer, the stocks of nitrate nitrogen were close to the stocks of the autumn observation period of 2019, and ammonium nitrogen decreased by 285 kg/ha.
