Effect of cropping frequency on C storage in Canadian prairie soils
Available water is the main constraint to crop production on the Canadian prairies. Summerfallow has been used to counter this problem, but frequent summerfallowing promotes soil organic matter (SOC) loss. Although ...
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 ...
Effect of crop rotations on potentially mineralizable-N and amino compounds in a Black Chernozem at Indian Head
The effect (i) of fertilization on fallow-wheat (F-W), F-W-W, and continuous wheat; (ii) of baling straw on F-W-W (fertilized); (iii) of including sweetclover as green manure (GM) in F-W-W (unfertilized); and (iv) of ...
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 ...
