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 ...
Dynamics of carbon dioxide evolution from decomposing wheat straw
Increasing concentration of CO2 in the atmosphere is a concern because of the potential for global warming. Carbon exchange between soil and the atmosphere has an important role in the global C cycle, but partitioning soil ...
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 ...
Assessing chemical methods for estimating mineralizable nitrogen in Saskatchewan soils
An experiment was conducted to correlate the potentially mineralizable nitrogen (NO) in Saskatchewan soils with chemical extractant. An array of soils (129) representing all soil zones, soil textures and crop management ...
Water use efficiency and precipitation use efficiency of crops in the semiarid prairie
The importance of water use efficiency (WUE) in crop production, in the semiarid prairie, is based on the fact that the available water is the most limiting factor influencing crop production. This poster compares water ...
