Split nitrogen applications for management of yield and protein of wheat grown in dryland
The feasibility of using split-N applications for managing yield and protein of wheat grown on dryland was studied in a field experiment initiated on a sandy loam and silt loam near Swift Current. Spring wheat was grown ...
A bioenergy success story: the energy savings implications of the increase in legumes in rotations since 1990
The energy savings achieved by the increase in field peas and lentil production in western Canada between 1990 and 1995 were calculated to be 4.46 PJ (petajoules) per year, equivalent to 1.7 % of the total energy costs of ...
Impact of crop rotation and tillage on some soil quality characteristics
An 11-yr rotation-tillage experiment conducted on a coarse-textured, Brown Chernozemic soil at Cantaur, southwestern Saskatchewan, was used to demonstrate the beneficial effects of reducing cropping frequency and tillage ...
Simulating the dynamics of soil organic matter in long-term rotation plots of Saskatchewan and Alberta
This study used the Century soil organic matter (SOM) model to simulate the dynamics in soil organic carbon, nitrogen, and phosphorus in long-term crop rotation studies established in Saskatchewan and Alberta. Observed ...
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 ...
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 ...
