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 ...
Nitrogen fertilizer management for maximum economic yields of spring wheat in southwestern Saskatchewan
The effects of snow trapping by means of alternative cereal stubble heights, and of N fertilizer management in terms of rates, times of application, and methods of placement on soil moisture conservation, grain yields, and ...
Simulating nitrate leaching under dryland conditions: model validation for water and solute movement
There is an increased awareness of the possible leakage of nitrate out of agricultural systems and its potential to contaminate underground and surface water. This has led to the use of simulation mode s for studying the ...
