The release of N from legume crop residues in the field can potentially be an important nutrient source for succeeding cereal crops, particularly in soils which are N deficient. Field studies were conducted in 1996 on two ...

Blackleg of canola (Brassica napus), caused by two Leptosphaeria spp, is a significant constraint to canola production worldwide except in china where only the less virulent L. biglobosa has been reported. In China, the ...

The effects of Roundup-Ready (RR) corn, grown in monoculture or in rotation with canola, on microbial biomass and diversity in corn rhizosphere were investigated at Lethbridge from 2002 to 2004. In monoculture, weeds in ...

Fusarium head blight (FHB) in barley has been spreading on the Canadian Prairies for the last decade. Fusarium spp. causing FHB can also cause crown/root rot of cereal crops. It is therefore of interest to determine the ...

Fusarium head blight (FHB) in barley is well established in the eastern Canadian Prairies and appears to be moving westward. A survey of 192 barley crops in eastern Saskatchewan was conducted to determine the impact of ...

Organic farmers across Saskatchewan face widespread phosphorus (P) shortages. Due to the lack of inputs in organic systems, organic farmers must rely on mechanisms like crop rotation and naturally-occurring arbuscular ...

Increasing demand for potatoes from Manitoba, mostly from the expanding french fry processing industry, has increased the need for acreages suitable for irrigated potato production. That need can be met by bringing additional ...

Several soil biochemical processes related to soil fertility are microbially mediated. We know very well the factors limiting crop production but know little of the factors limiting the soil microbial community. The goal ...
