Influence of direct sowing in crop rotation on some soil structure indices

The paper presents results on the influence of four-year simplified tillage and direct sowing in the 4-year long crop rotation on some soil structure and water stability indices. The results obtained indicate a significant influence of tillage and direct sowing on the soil structure. The experiment showed that compared with traditional tillage and direct sowing, overall soil clodiness was improved and soil pulverisation was lowered. A significant increase of the mean weight diameter of aggregates was found with a simultaneous increase of water stability properties.
