Simulating the dynamics of soil organic matter in long-term rotation plots of Saskatchewan and Alberta
This study used the Century soil organic matter (SOM) model to simulate the dynamics in soil organic carbon, nitrogen, and phosphorus in long-term crop rotation studies established in Saskatchewan and Alberta. Observed ...
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, ...
Spring wheat response to nitrogen and water
Yield trends of wheat – impact of fertilization and legume
A long-term (34-yr) crop rotation experiment being conducted at Indian Head, Saskatchewan, on a thin Black Chernozem with heavy clay texture, was used to assess the influence of fertilizer (N and P), sweetclover green ...
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 ...
