Image analysis is a valuable tool that can be used to delineate management units for Site-Specific farming applications. Soil landscapes are often highly variable in terms of their productive potential. Because of the ...

The feasibility of variable rate N fertilization was assessed during a single growing season at Birch Hills, Saskatchewan, Canada (105” 2’ W, 53” 3’10 N). The experiment was carried out across a 120 m x 620 m wheat field, ...

The efficiency and benefits of split N applications by cereals and oilseed was evaluated at the Irrigation Fann at Outlook. In 1988, canola (Westar) received 0, 75 + 75, or 150 kg N/ha in the form of urea (U) or urea-ammonium ...

At nine locations, selected throughout the Brown, Dark Brown and Black Soil Zones, wheat and barley were grown on summerfallow (9 locations), cereal (8 locations) and oilseed stubble (6 locations). In total, 46 experimental ...

A landscape-scale study was conducted near Biggar, SK, to estimate N2 fixation by chickpea (Cicer arietinum) using the natural 15N abundance method. The spatial variability of N2 fixation was investigated at both the ...

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, ...

One benefit often cited for legumes crops is that they contribute N to subsequent crops, but the magnitude of this effect has been difficult to quantify. A study was conducted to compare how much and when N from fertilizer ...

Incorporation of legumes in a cropping system has positive agronomic benefits to subsequent crops, particularly cereals. These benefits are associated with improved N availability to the subsequent cereal and/or non-N ...

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, ...
