Influence of organic fertilizer and soil tillage in crop rotation on the structure-formation and water-durability of aggregate of arable sod-podzolic soil

Pegova N.A.


The dominant influence of soil tillage on aggregate and water-stable composition of sod-podzolic arable soil is revealed. Replacement of bladed autumn ploughing by surface tillage and manuring had less destroying effect on water-stable composition of soil. Micro-aggregates and lumpy soil fraction are subject to seasonal mutual transformation.

Keywords: ploughing, surface tillage, manure, aggregate contents, water-stable aggregate, coefficient of aggregation, coefficient of water-durability
