Effects of grain lentil-wheat and monoculture wheat on crop production and N fertility in a Brown loam
Low commodity prices and a desire by producers on the Canadian prairies to reduce fertilizer N inputs has resulted in a marked increase in grain lentil production in recent years. Because a large proportion of the pulse ...
Spring wheat response to nitrogen and water
Economic and risk considerations of nitrogen fertilizer use in the Brown Soil Zone
Optimum use of nitrogen fertilizer requires consideration of factors that influence plant response and those that govern the decisions of producers. The response of spring wheat to soil moisture and N fertilizer was assessed ...
Fertilizer application and deep leaching of nitrate under long term crop rotation
It is commonly believed that the use of nitrogen fertilizers in agriculture will lead eventually to the loss of nitrate via leaching. The nitrate leached below the root zone has the potential to contaminate underground ...
The long-term agronomic and economic effects of crop rotations in western Canada
Agriculture Canada Research Stations in western Canada have conducted more than 68 long-term crop rotation experiments since the early 1900's; twenty of these are still ongoing. A committee of scientists, representing all ...
Moisture conservation and use at Swift Current – a comparison to previous findings
The results of an ongoing 18-year crop rotation study at Swift Current were compared to those reported 30-40 years earlier. The two periods showed no difference in over winter moisture conserved for stubble or fallow-systems. ...
