Effects of fallow replacement green manuring with annual legumes on soil nitrogen availability
Legume green manures are used in crop rotations to enhance soil nitrogen availability and to provide ground cover for soil conservation. The annual legumes Black Lentil, Chickling Vetch, Tangier Flatpea, and a Feedpea ...
Relationship between soil texture and soil organic carbon at small field scale
The capacity of a soil to store organic carbon is related to its particle size distribution, or soil texture, mainly because the capacity of clay particles to stabilize organic materials. A study of the relationship of ...

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 ...
