The influence of agrotechnological techniques on the maintenance and reserves of motrmass in sod-podzolic sandy loam soil

Abstract

The influence of tillage methods and fertilizer systems on the content and reserves of mortmass and C_MM in layers of 0–10 cm and 10–20 cm of sandy loam soil was assessed, their dynamics during the growing season of winter wheat was established. During the observation period, the highest rates in the experiment were noted when disking in a layer of 0–10 cm in spring at the beginning of growing season with an organic-mineral fertilizer system with treatment of straw with Zhytsen microbiological fertilizer or applying a compensating dose of nitrogen in the form of CAS (the content of mortmass was at the level of 5200 mg/kg, carbon – 1298–1322 mg/kg; reserves – 6812 and 1112–1186 kg/ha, respectively).
