Influence of long-term application of N and S fertilizers (1980-2002) and liming in 1992 on dry matter yield of grass and soil properties in a Dark Gray Chernozem in north-central Saskatchewan
Most soils are deficient in plant-available N in the Prairie Provinces of Canada, and in the Parkland region, many soils are also insufficient in available S for high crop yields. Long-term field experiments, initiated in ...
Effectiveness of elemental S fertilizers on canola after four annual applications
Plants feed on sulphate-S, but now elemental S fertilizers (which cost less per unit of S than the sulphate-S fertilizers) are available for commercial use. The effectiveness of elemental S fertilizers depends on how ...
Optimizing yield and quality of canola seed with balanced fertilization in the Parkland Zone of western Canada
A number of field experiments were conducted from 1998 to 2001 (or are underway) in northeastern Saskatchewan to determine the effects of various rates (0 to 30 kg S/ha), sources (sulphate S – potassium sulphate and ammonium ...
Effectiveness of elemental S fertilizers on canola after three annual applications
Plants feed on sulphate-S, but now elemental S fertilizers (which cost less per unit of S than the sulphate-S fertilizers) are available for commercial use. The effectiveness of elemental S fertilizers depends on how quickly ...
Effectiveness of elemental sulphur fertilizers on canola in the first year of application
Canola is the major cash crop in the Parkland zone, where many soils are deficient in plant-available S for high seed yields. Canola has high requirements for S. Deficiency of S at any growth stage can cause drastic reduction ...
Canola cultivar by sulphur fertilizer rate interaction effects on seed yield and quality
In recent years, many farmers in the Parkland zone experienced substantial loss in seed yield due to severe S deficiency in the growing season. Canola has high requirements for S which may vary with cultivars (and canola ...
