Dynamics of carbon dioxide evolution from decomposing wheat straw
Increasing concentration of CO2 in the atmosphere is a concern because of the potential for global warming. Carbon exchange between soil and the atmosphere has an important role in the global C cycle, but partitioning soil ...
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 agronomic practices can reduce the effect of Fusarium head blight on durum wheat in Saskatchewan?
Fusarium head blight (FHB) has become an important disease of cereals in moist regions of western Canada. This disease has played an important role in contributing to lower grain yields and substantial downgrading of durum ...
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 ...
Why are tame hay yields declining in Saskatchewan?
Provincial agricultural production statistics show that grain crop yields have generally increased over the past 35 years while tame hay yields peaked in 1980 and have since been in decline. Weather data from 16 sites ...
