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, ...
Nitrogen effects on water use efficiency in the semi-arid Canadian prairies
In the semiarid environment of the Canadian prairies, water is the main constraint to crop production. Few studies have examined the influence of fertilizer on water use efficiency (WUE) and fewer still have made comparisons ...
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 ...
Effect of cropping frequency on C storage in Canadian prairie soils
Available water is the main constraint to crop production on the Canadian prairies. Summerfallow has been used to counter this problem, but frequent summerfallowing promotes soil organic matter (SOC) loss. Although ...
