Factors affecting spatial variation in two crop rotations
An experiment was initiated at two 4-ha sites with hummocky to undulating terrain, to examine the spatial variation rotation benefits of wheat grown after pea compared to wheat grown after wheat. In the second year of the ...
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 ...
Landscape-scale variability of N2 fixation by pea
The landscape-scale variability of N2 fixation by pulse crops is an important part in the intensity of N cycling in a hummocky terrain. A 100-gridpoint landscape-scale research design was established at a site in the thick ...
A landscape-scale assessment of the nitrogen and non-nitrogen benefits of pea in a crop rotation
The inclusion of a pulse crop in a rotation could influence the seed yield of a succeeding cereal crop in different slope positions of a field. A landscape-scale study was established in 1993 to examine the N contribution, ...
Landscape-scale controls on the availability of pea-residue nitrogen for the subsequent wheat crop
Increased N uptake is a major mechanism responsible for the rotation benefit of a pulse crop to a succeeding cereal crop. The objective of our study was to determine the sources of N in pea-wheat vs. wheat-wheat rotation ...
