[Influence of basic cultivation of sod-podzolic light loamy soil on its properties and yielding capacity of agricultural cultures]
Afanasyev, N.I.(Institute for Soil Science and Chemistry, Minsk (Belarus))
There were invesigated the following tillage forms of the soil: moldboard ploughing on 20-22 cm; shalow tillage (shelling on 6-8 cm + doscing on 10-12 cm; shallow tillage 3 years, moldboard ploughing - 1 year; chiseling on 20-22 cm + subsoiling on 45 cm; chiseling on 20-22 cm). Bulk density, porosity, heat capacity, diffusion gases, aeration, moisture were investigated. Moldboard ploughing more then other cultivation change physical properties of arable layers. Shelling tillage least effective (yield-6,88 t/ha forage units), subsoiling - best tillage (yield 7,37 t/ha forage units for crop-rotation). The deficit of soil moisture limit's soil fertility
