Biological activity of the soil when using organomineral and water-soluble fertilizers in the agrophytocenosis of winter triticale

When using water-soluble fertilizers on an organomineral background, the total number of soil bacteria significantly exceeded the control indicators. The use of phytohumate in the tillering and earing phase contributed to both a high respiration rate of 0.121–0.128 MGCO2/100g /day and cellulose decomposition of 24.08–31.37%. The treatment of crops in the tillering phase with Aquarin fertilizer No. 8 against the background of WMD provided a respiration rate of 0.094–0.12 MGCO2/100g /day, and the decomposition of cellulose ranged from 23.15-29.56%. The high biological activity of the soil had a positive effect on the productivity of winter triticale. Grain yield in variants with the use of water-soluble fertilizers, on average for 3 years, fluctuated at the level of 3.02 t/ha - 4.26 t/ha, which is significantly higher than the control variant of 2.59 t/ha.
