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 ...
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 ...
Long-term use of urea vs. anhydrous ammonia for N-fertilization of a Dark Brown loam: III. Soil microbial populations and activities
The influence of fertilizers on soil quality, including soil microbial well-being, has been frequently questioned by proponents of organic farming and Low Input Sustainable Agriculture (LISA). A 10-yr experiment, conducted ...
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 ...
Effect of rainfall on N and P changes in fallow loam
Olsen-P distribution in a thin Black Chernozem as influenced by fertilizers and crop rotations
Inorganic phosphorus (P) is generally believed to be relatively immobile in Chernozemic soils. However, available P (e.g., Olsen-P) has been found at depth in some soils and this has been postulated to be either the result ...
Effect of legume green manuring on microbial populations and activity in a Brown loam
In a seven-year plot experiment, conducted on a Brown Chemozemic loam at Swift Current, SK to evaluate four annual legumes for fallow (F) replacement green manuring (GM), the surface soil (0-10 cm) under wheat (W) stubble ...
Effect of zero-till continuous wheat on soil quality after four and six years
After four and six years of continuous spring wheat cropping using zero-tillage on the N × P × Snow-trap test site, soil samples were taken from the test area and from the adjacent area which has been in a wheat-fallow ...
