The paper aimed at establishing the degree of modification of the agrochemical and agrophysical indices of leached chernozem under the influence of different types of manure. Comparative action of cow manure (conventional), mixed manure from rural households, pig and poultry manure was studied. It has been established that manure of different types has increased the organic matter content in soil by 0.13-0.33% or 3172-7986 kg/ha. Of the total amount of carbon incorporated in soil with cow manure and mixed manure, at the dose of N170, the amount of humified carbon was about 46-52%.When applying pig and poultry manure, the amount of humified carbon was about 43-79%. The types of used manure mobilized and contributed to the increase in NPK content in the arable soil layer. Cow manure and mixed manure ensured a significant increase in mobile phosphorus content and exchangeable potassium of 4.14-4.77 and 13-15 mg/100g of soil. All the manure, regardless of its origin, after the decomposition of the organic matter, had a beneficial action on the physical properties of the soil. |
