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 ...
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 ...
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 ...
Crop rotation and tillage impact on carbon sequestration in Saskatchewan soils
Six field experiments from the Brown to Black soil zones and from light- to heavy-textured soils in Saskatchewan were conducted to quantify C sequestration under different tillage and crop rotations. Continuous cropping ...
