Carbon isotope discrimination (CID) has been proposed as a secondary trait to indirectly select for improved water use efficiency and seed yield. To determine the effectiveness of CID to indirectly select for seed yield, ...

Nitrous oxide has been widely recognized as a major scientific and environmental issue because of its involvement in global warming and destruction of the atmospheric ozone layer. Soils generally act as source of N2O, but ...

Rhizobium leguminosarum biovar viceae are not native to Saskatchewan, but numbers of rhizobia in excess of l0^4 g-1 soil have been observed in fields previously grown to inoculated field pea (Pisum sativum L.). Modified ...

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 study was conducted near Dinsmore, SK in the Dark Brown Soil Zone to determine the landscape-scale variability of N2-fixation and N balance of a lentil crop. Stable 15N isotope dilution method was used to determine ...

Nitrous oxide has been widely recognized as a major scientific and environmental ‘issue because of its involvement in global warming and destruction of the atmospheric ozone layer. The inherently high temporal and spatial ...

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, ...

The fertilizer-N use efficiency of irrigated canola, softwheat, durum, and spring wheat was determined in 1988 and 1989. Crops received various amounts of N, applied at time of seeding or split between time of seeding and ...
