Total and labile soil organic N as influenced by crop rotations and tillage in Saskatchewan soils
Crop rotations and tillage practices affect quantity and quality of soil organic N (SON). Six field experiments varying from 8 to 25 years across various soil zones in Saskatchewan were conducted to evaluate the impact of ...
The long-term agronomic and economic effects of crop rotations in western Canada
Agriculture Canada Research Stations in western Canada have conducted more than 68 long-term crop rotation experiments since the early 1900's; twenty of these are still ongoing. A committee of scientists, representing all ...
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 ...
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 ...
