Factors limiting soil microbial growth and activity in wheat-based cropping systems
(2004-02-19)
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 ...
Microbial phosphorus pools in a long-term organic farming system in Scott, Saskatchewan
(2013-03-05)
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 ...
Residual effects of preceding crops on wheat yield and profitability
(2020-03-10)
A four-year cycle crop rotation study (cereal crop with a range of legumes and oilseeds at different frequencies and sequences in rotation) was established from 2010-2018 at three locations in western Canada to evaluate ...
Tillage system and cropping sequence effects on common root rot of barley in eastern Saskatchewan
(2007-03-01)
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 ...
Survival of blackleg pathogen inoculum in canola stubble under simulated flooding conditions
(2012-03-13)
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 ...
Barley after hay: grass matters!
(2003-02-18)
Perennial forage crops are not traditionally grown in crop rotations in the Brown soil
zone for several reasons: i) they are slow to establish; ii) they require intensive tillage to
terminate; and iii) they reduce yield ...
Microbial biomass and diversity in roundup-ready corn rhizosphere
(2007-03-01)
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 ...
