Long-term straw management and N fertilizer rate effects on crop yield, N uptake and N balance sheet in a Gray Luvisol
A field experiment with barley monoculture (1983-1996), and wheat/barley-canola-triticale-pea rotation (1997-2009) was conducted on a Gray Luvisol [Typic Haplocryalf] loam soil at Breton, Alberta, to assess the influence ...
Improving organic C and N in a sulphur-deficient soil with S fertilization
A field experiment was conducted over nine years (1999 to 2007 growing seasons) in northeastern Saskatchewan on a S-deficient Gray Luvisol (Typic Haplocryalf) soil to determine the relative effectiveness of N alone versus ...
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 ...
