Changes in soil biological and physical properties under reduced tillage systems
Interest in reduced tillage systems has increased in recent years, though important questions remain as to the impacts of such systems on soil quality and nutrient cycling. We examined the effects of tillage on soil ...
Wild oat nutrient uptake and release from residue
Nitrogen release, uptake, and yield of wheat in the Brown Soil Zone at the landscape-scale as influenced by tillage treatments
Comparison of the effects of short-term mechanical and no-till fallow managements on nitrogen (N) availability was conducted in an undulating landscape in the Brown Soil Zone in southwestern Saskatchewan. The effects of ...
The influence of crop residues on plant phosphorus uptake
Two growth chamber experiments were performed to determine the short term contribution of legume residues to soil phosphorus supplies. In the first experiment, fresh pea residues of different ages were applied to soil in ...
