Content and Balance of Trace Elements (Co, Mn, Zn) in Agroecosystems of the Central Chernozemic Region of Russia

This work is devoted to the study of provision arable soils with mobile forms most important trace elements (cobalt, manganese, and zinc). In modern Russian agriculture, low one reasons leading lower yields deteriorating quality crops. The materials regional local agroecological monitoring in Belgorod region, which part Central Black Earth region Russia, were used this work. results showed that average gross contents zinc, cobalt chernozems typical forest-steppe zone respectively 345, 36.5, 8.48 mg/kg, common steppe 397, 42.9, 9.51 mg/kg. distribution studied profile chernozems, a tendency gradual decrease their concentrations increasing depth was revealed. According for 2015–2018, it found proportion content compounds zinc (<2 mg/kg) 90.3%; (<0.2 manganese (<10 mg/kg), proportions 99.3% 38.6%, respectively. these soils, advisable introduce microfertilizers containing are deficit. main sources input agroecosystems organic fertilizers, account 79.3%, 86.3%, 66.6% total amounts, Losses from mainly occur as result washing away soils—82.8% 96.8% losses, respectively—and 60.5% losses due alienation by marketable crop. A positive balance had been feature an intensity 106%, while negative balance, intensities 61.3% 25.3%,
