Reduced diversity of AM fungi in annually cropped fields of the Canadian prairie

Hamel, C.; Dai, M.; Bainard, L.; Wang, H. (2013-03-05)

The arbuscular mycorrhizal (AM) fungi are important service providers to agriculture that are impacted by certain cultural practices. We assessed the status of AM fungal resources in the Prairie, from the Grey to the Brown ...

Influence of pesticides on pathogen populations and biological control agents

Fernandez, M.R.; Zentner, R.P.; Gehl, D. (2011-03-15)

Mobility of copper fertilizers in soils

Flaten, P.L.; Walley, F.L.; Karamanos, R.E. (2002-02-20)

Due to its cationic nature, Cu mobility is assumed to be very limited in Prairie soils, which are dominated by negatively charged constituents (McLaren et al., 1983). Clay and organic matter are major sources of these ...

Effect of cropping frequency, wheat classes, and flexible rotations on yield, production, and nitrogen economy in a Brown Chernozem

Campbell, C.A.; Zentner, R.P.; Selles, F.; Lemke, R.; Jefferson, P.G.; McConkey, B.G.; Gan, Y. (2003-02-18)

Producers in the semiarid Canadian prairies frequently summerfallow (F) to conserve water, control weeds, and to maximize soil N reserves; however, this practice often results in soil degradation. A crop rotation experiment ...

Dry heat disinfection versus seed borne Fusarium – six years of practical experience

Gehl, D. (2008-02-28)

Enhanced UV-B effects on wheat under different temperature, solar light, and soil moisture

Zheng, Y.; Guo, X.; Zhang, C. (2004-02-19)

Ultraviolet radiation-B (UV-B) will increase in the future due to the Ozone depletion; global climatic factors, such as temperature, precipitation, evapotranspiration, soil moisture and CO2 content, are changing because ...

Soil fertility research and extension in Oregon

Christensen, N.W.; Hart, J.M. (2012-03-13)

This report describes our approach to and philosophy behind development of soil fertility research and Extension programs at Oregon State University since 1980. Three examples describe how fertilizer management was used ...

A decade of herbicide-resistant crops in Canada

Beckie, H.J.; Harker, K.N.; Hall, L.M.; Warwick, S.I.; Légère, A.; Sikkema, P.H.; Clayton, G.W.; Thomas, A.G.; Leeson, J.Y.; Séguin-Swartz, G.; Simard, M.-J. (2006-03-02)

This review examines some agronomic, economic, and environmental impacts of herbicide-resistant (HR) canola, soybean, corn, and wheat in Canada after 10 years of growing HR cultivars. The rapid adoption of HR canola and ...

Fusarium species in underground tissue of pulse, oilseed, and cereal crops grown in southeast Saskatchewan

Fernandez, M.R. (2004-02-19)

A total of 643 cereal, oilseed and pulse crops were sampled in southeast Saskatchewan in 2000 and 2001 for Fusarium populations in underground living tissue. Many of the Fusarium spp. isolated from discolored roots/subcrown ...
