Relationship between soil texture and soil organic carbon at small field scale
The capacity of a soil to store organic carbon is related to its particle size distribution, or soil texture, mainly because the capacity of clay particles to stabilize organic materials. A study of the relationship 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 ...
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 ...
Relationship between mineralizable N and hot KCl extractable NH4-N – variability at one site
To characterize the N supplying capacity of the soil at a site where a new long-term experiment was being initiated at Scott, Saskatchewan, we soil sampled the site in a systematic manner, taking 160 cores. We used these ...
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 ...
