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 ...
Yield trends of wheat – impact of fertilization and legume
A long-term (34-yr) crop rotation experiment being conducted at Indian Head, Saskatchewan, on a thin Black Chernozem with heavy clay texture, was used to assess the influence of fertilizer (N and P), sweetclover green ...
Effect of cropping frequency on C storage in Canadian prairie soils
Available water is the main constraint to crop production on the Canadian prairies. Summerfallow has been used to counter this problem, but frequent summerfallowing promotes soil organic matter (SOC) loss. Although ...
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 ...
Effect of crop rotations on potentially mineralizable-N and amino compounds in a Black Chernozem at Indian Head
The effect (i) of fertilization on fallow-wheat (F-W), F-W-W, and continuous wheat; (ii) of baling straw on F-W-W (fertilized); (iii) of including sweetclover as green manure (GM) in F-W-W (unfertilized); and (iv) of ...
