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 ...
