The Effect of Tillage Practices on the Agrophysical Properties of Eroded Soddy-Podzolic Soils and the Agricultural Crop Yield

摘要

The effect of basic tillage practices on and the yield of agricultural crops the agrophysical properties of eroded soddy-podzolic soils on morainic loams was studied. It was found that surface tillage results in the compaction of the plow layer and a decrease in total and aeration porosity. Subsoiling improves the parameters of soil erosion stability it increases the content of water-stable aggregates, their weighted mean diameter, and water the stability coefficient.
