EFFICIENCY OF A NEW FERTILIZING MELIORANT OF GOAT-BASED MANURE ON SOIL AND PLANTS

Most of the lands previously drained in the Ryazan Meshchera need restoration due to the development of degradation processes. This is possible by the technology implementation of new fertilizing ameliorants application into the peat soil. The authors have developed a new fertilizer ameliorant based on goat manure with the addition of municipal sewage sludge, chopped straw and Baikal EM-1 agent in an environmentally friendly ratio. Investigations were carried out in an inlet experiment set up at the lysimetric station in Polkovo, Ryazan District, according to the generally accepted technique with a scheme for the application of a fertilizer ameliorant in different doses. A vegetative experiment in vessels, carried out to study the effectiveness of a new fertilizer ameliorant goat-based manure on soil and plants, showed the following results: an increase in the concentration of nitrogen in total, mobile phosphorus and exchangeable potassium by 1.0-2.7 %, 0.3-0.7 % and 0.01-0.02 % compared to the control; an increase in the height of barley plants by 7.5-1.5 % in comparison with the control; an increase in the total protein content in barley grain was accompanied by a decrease in low-molecular-weight fractions and the dominance of high-molecular ones due to an increase in hordein by 3.5- 6,0 % compared to the control; the concentration of heavy metals in soil, straw and grain did not exceed the sanitary standard; the content of pathogenic microflora and helminth eggs in the soil was not found. Option 3 is considered the most optimal from the agronomic point of view - the application of a fertilizer ameliorant of 15 t/ha.
