Total and labile soil organic N as influenced by crop rotations and tillage in Saskatchewan soils
Crop rotations and tillage practices affect quantity and quality of soil organic N (SON). Six field experiments varying from 8 to 25 years across various soil zones in Saskatchewan were conducted to evaluate the impact of ...
Effect of fertilizer, legumes and cropping frequency on soil organic matter in a long-term rotation – changes after 6 years of zero tillage
Society is interested in methods of increasing C storage in soil, so as to reduce CO, concentration in the atmosphere, which may contribute to Global warming. Scientists have demonstrated that the adoption of better ...
Effect of tillage on selected soil biochemical characteristics in a coarse- and medium-textured soil in southwestern Saskatchewan
Characterization of soil organic matter is valuable for identifying the overall quality of soils. Crop management will influence soil quality. Some changes may become apparent more quickly than others and may depend upon ...
Effect of soil moisture and soil organic matter on soil bulk density during a growing season
We measured surface (0-7.5 cm) soil bulk densities at nine sampling times for two and four long-term crop rotations at Swift Current and Indian Head respectively, to determine the effect of crop management and time. In a ...
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 ...
Economic and risk considerations of nitrogen fertilizer use in the Brown Soil Zone
Optimum use of nitrogen fertilizer requires consideration of factors that influence plant response and those that govern the decisions of producers. The response of spring wheat to soil moisture and N fertilizer was assessed ...
