The use of organic fertilizers based on waste mushroom compost in agricultural crop production technologies

Abstract

The article presents analyses of experimental data on growing agricultural crops with the use of organic fertilizers based on compost obtained by introducing waste mushroom compost into the soil. The presented data of studies carried out in conditions of Ryazan region on a dark gray forest soil allow to conclude that both fresh compost and one-year-old compost had an increase in all biometric indicators of crops. At the same time, fresh compost gave a greater increase. According to the results of the field experiment, the maximum yield for all crops was observed in variants with semi-rotted compost: the yield of spring wheat was 2.82 t/ha (+ 0.23 t/ha to the control); that of spring barley was 3.21 t/ha (+0.17); that of spring rape was 1.77 t/ha (+0.24); that of Vympel potatoes was 27.91 t/ha (+ 4.41); that of Kolobok potatoes was 11.21 t/ha (+1.63); that of edible pea was 2.10 t/ha (+0.21). The test results of composts made it possible to recommend them as an organic fertilizer to optimize nutritional conditions.
