Long-term tillage and crop rotation effect on soil aggregation
Tillage and cropping sequences play a key role in controlling soil aggregation. We measured water-stable aggregate (WSA), wind erodible fraction (WEF), and geometric mean diameter (GMD) for six mid to longterm (8 to 25 ...
A simple model for quantifying change in soil organic C as influenced by tillage and crop rotations on the Canadian prairies
Simulation models are required for quantifying the impact of crop rotations and tillage on soil organic C dynamics, and for aggregating C sequestration over a relatively large area. However, most current models of soil ...
Effect of zero-till continuous wheat on soil quality after four and six years
After four and six years of continuous spring wheat cropping using zero-tillage on the N × P × Snow-trap test site, soil samples were taken from the test area and from the adjacent area which has been in a wheat-fallow ...
