Sustainable agriculture – some complicating interactions
There have been numerous definitions of 'Sustainable Agriculture' put forth, but we address the official one adopted by Agriculture Canada: "Sustainable agricultural systems are those that are economically viable, and meet ...
Managing an annual legume green manure crop for fallow replacement in southwestern Saskatchewan
Some scientists have suggested that in the Brown soil zone an annual legume green manure crop (GM) could be used as a partial-fallow replacement to protect the soil against erosion and increase its N fertility, particularly ...
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 ...
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 ...
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 ...
