Effects of fallow replacement green manuring with annual legumes on soil water reserves
Legume green manures are used in crop rotations to add organic matter, enhance N availability and to provide ground cover for soil conservation. In drought-prone regions like the Palliser Triangle, annual rather than ...
Zero-minimum tillage seeding and fertilizer placement techniques for zero-tillage
Preliminary results from the field evaluation of zero and minimum tillage seeding machines, as well as fertilizer placement techniques for zero-tillage are presented. Narrow hoe opener (Noble 2000), conventional double-disc ...
Screening for salt tolerance in native and exotic shrub willow
(University of Saskatchewan, 2010-03-31)
Dryland salinity is a significant agronomic problem across the Canadian prairies, with an estimated four million hectares of salt-affected land. The potential exists to make better use of saline marginal lands by developing ...
Does seed size affect alfalfa establishment and productivity in saline seedbeds?
Large, medium and small seeds of Rangelander alfalfa, were sown in saline media in Canada’s Salt Tolerance Testing Lab. The emergence and survival data indicate that large-size seeds confer a degree of salinity tolerance ...
Using flow gauges to determine leaf specific conductance in hybrid poplars under mesic and xeric conditions
A study was conducted using sap flow gauges to determine leaf specific conductance (LSC) in hybrid poplars in an environmentally-controlled greenhouse at Swift Current, Saskatchewan. Sap flow rates were compared between ...
