ECOLOGiCal and AGROCHEMICAL ASSESSMENT OF FARMING ON THE Sod-PODZOLIC sandy loam SOILS OF UKRAINIAN POLISsya

Abstract

The studies were carried out in the stationary lysimetric system with soddy-podzolic sandy loam soils of Ukrainian Polissya in 2006-2013. The effect of individual crops, fertilizer systems, calcium-containing mutters and inoculation of seeds on the infiltration losses of moisture, water-soluble organic matter and nutrients (N, P, K, Ca, Mg) has been studied. The largest losses were in the soil under steam and tilled crops so as under the mineral and organic fertilizer system. Ways of regulation the balance of moisture and biogenic elements in sod-podzolic sandy loamy soils have been determined. From the point of view of resource saving, the best technological methods are the increase of winter cereals in crop rotation, using the green manure, inoculation of the seeds and application of calcium-containing matters by the half of norm every 5 years or quarter of the norm every year.
