Impact of crop rotation and tillage on some soil quality characteristics
An 11-yr rotation-tillage experiment conducted on a coarse-textured, Brown Chernozemic soil at Cantaur, southwestern Saskatchewan, was used to demonstrate the beneficial effects of reducing cropping frequency and tillage ...
Long-term use of urea vs. anhydrous ammonia for N fertilization of a Dark Brown loam: I. Soil acidification and nutrient availability
The decline of indigenous soil fertility on the pra1r1es has necessitated higher nitrogen fertilizer inputs into cropping systems. Our objectives were to quantify the acidifying effects of urea and anhydrous ammonia nitrogen ...
Fertilizer application and deep leaching of nitrate under long term crop rotation
It is commonly believed that the use of nitrogen fertilizers in agriculture will lead eventually to the loss of nitrate via leaching. The nitrate leached below the root zone has the potential to contaminate underground ...
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 ...
Effect of tillage on selected soil biochemical characteristics in a coarse- and medium-textured soil in southwestern Saskatchewan
Characterization of soil organic matter is valuable for identifying the overall quality of soils. Crop management will influence soil quality. Some changes may become apparent more quickly than others and may depend upon ...
