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 ...
Forage yield of unfertilized perennial crops in simple and complex mixtures under two management strategies in northeastern Saskatchewan
A field experiment was sown on May 27, 2008 at Melfort, Saskatchewan (52O44’N 104O47’W) on a thick Black Chernozem (Udic Boroll) silty clay soil to compare the effects of perennial forage crop monocultures and mixtures on ...
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 ...
Effect of repeated additions of liquid swine manure and solid cattle manure on soil organic carbon
The agronomic effects of liquid swine manure and solid cattle manure application on soil nitrogen (N) and crop yield in Saskatchewan soils has been well documented (Mooleki et al. 2002b, Mooleki et al. 2004). However, the ...
Fertilizer-N management and nitrous oxide emissions from four sites in Saskatchewan
Nitrous oxide (N2O) is a powerful greenhouse gas that also depletes stratospheric ozone. The use of fertilizer-N for agricultural purposes is thought to contribute significantly to Canadian anthropogenic N2O emissions. ...
