Does crop residue N influence soil N availability?
A landscape study was conducted near Biggar, Saskatchewan, to study the influence of crop residues on the availability of soil N in the second phase of crop rotations. In order to compare leguminous and cereal residues, ...
A field-scale assessment of the rotation benefits of pea and canola
Producers and researchers have observed that higher cereal yields occur when oilseed and pulse crops are included in a cereal-intensive cropping system. A study was established in the spring of 1996 to compare the rotation ...
Nitrification in adjacent cultivated and pasture landscapes – a comparison
Variability in nitrification and autotrophic nitrifying communities were assessed at shoulder and footslope positions of a cultivated and a pasture landscape. The sampling design was a systematic grid design and all analysis ...
Temporal availability of N to wheat in a lentil-wheat rotation
Incorporation of legumes in a cropping system has positive agronomic benefits to subsequent crops, particularly cereals. Some of these benefits are associated with improved N availability to the subsequent cereal. A study ...
Saskatchewan inoculants for chickpea and bean
A collaborative research project between the University of Saskatchewan, the Saskatchewan Wheat Pool, MicroBio RhizoGen Corp. and Westco. Fertilizers Ltd. was initiated in 1994 to identify and develop effective rhizobial ...
Leaching and recovery of 15N in dryland and irrigated cropping systems
Laird-lentil and Neepawa-wheat were grown under irrigation in 1987 at the experimental Irrigation Farm at Outlook under three levels of N: 10, 50, and 100 kg of NH4NO3, double labelled with 15N. A similar experiment was ...
