Microbial community structure under various wheat-based cropping systems
The effects of cropping systems on soil biological quality are slow to develop. We sampled the soil of a 36-year old long-term experiment established on an Orthic Brown Chernozem, at Swift Current SK, in the fall of 2003, ...
What happens to the soil organic matter if I till long-term no-till?
The long-term practice of no-till (low-disturbance direct seeding) is an effective method to increase the soil organic matter (SOM) content of the soil. If that increased soil organic matter is traded as an offset for ...
Seasonal variation in the soil microbial community in wheat-growing soil and influence of C, N, and P inputs
It has long been know that N and P fertilization increases plant growth and yield, but the impact of fertilization on soil microorganisms has rarely been considered. Long-term plots (36-year old) under fallow-wheat-wheat ...
Fertilizer-N management and nitrous oxide emissions from four sites in Saskatchewan
Nitrous oxide (N2O) is a powerful greenhouse gas that also depletes stratospheric ozone. The use of fertilizer-N for agricultural purposes is thought to contribute significantly to Canadian anthropogenic N2O emissions. ...
