Competitiveness-shifts from weeds to crops using arbuscular fungi
(2003-02-18)
Arbuscular fungi (AF) colonize ca. 80% of terrestrial plant roots and typically improve their growth by enhancing nutrient uptake, reducing disease severity and/or imparting resistance to abiotic stress. Therefore, ...
Reduced diversity of AM fungi in annually cropped fields of the Canadian prairie
(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 ...
Nitrogen supply from belowground residues of lentil and wheat to a subsequent wheat crop
(2014-03-11)
Lentil (Lens culinaris) plants can form an association with rhizobia and thereby biologically fix much of the nitrogen (N) required for their growth. This not only reduces the need for expensive N fertilizer when the lentil ...
Soil fertility research and extension in Oregon
(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 ...
Enhanced UV-B effects on wheat under different temperature, solar light, and soil moisture
(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 ...
Impact of tillage system, preceding crops, and P fertilizer on economic performance of flax production
(2004-02-19)
Conservation farming is a system approach that considers all factors that affect production. Reduced tillage is one of the methods of conservation farming and is becoming increasingly popular on the prairie. This will ...
Stubble effects on crop microclimate and crop performance in a sub-humid prairie climate
(2004-02-19)
Stubble impacts crop microclimate in ways that have not been well-investigated, particularly in the context of crop establishment, growth and yield. In this study, the effects of different stubble heights on crop microclimate, ...
