On Dark Brown soils, the use of a dual-inhibitor EEF resulted in increased grain yield and delivered improved net return benefit compared to urea. Other EEF sources tested yielded similarly in the Dark Brown soils. However, in the Black and Grey soils, the EEFs tested...

Research found increases in growing degree days, corn heat units, the number of frost-free  days, and average, maximum and minimum air temperature on the Prairies. Average annual precipitation and growing season precipitation have increased in Canada, but western Canada had increases in some regions and...

When Cu and Zn fertilizers were applied to phosphorus (P) deficient soils at 4.5 lbs/ac (5 kg/ha) rate, wheat yields were reduced. Symptoms of micronutrient metal toxicity were observed at early growth stages, and included purplish-red colour and chlorotic leaves. Liebig’s Law of the Minimum states...

Wheat, pea and canola uptake of copper (Cu), zinc (Zn) and boron (B) was greater with optimum soil moisture and warm temperatures compared to drought and saturated soil moisture conditions or cold temperatures. Micronutrient deficiencies can occasionally occur on Prairie soils, but crop response to fertilization...

Wheat midge parasitism was found to be as high as 71% in the Peace River region of Alberta.  Parasitism was primarily by Macroglenes penetrans, the main parasitic wasp species that attacks wheat midge on the Canadian Prairies.  A parasitic wasp species, Inostemma walkeri, was newly...

Wheat, canola and chickpea yield and the overall average water use efficiency increased linearly as stubble height increased to 18 inches (45 cm) compared to cultivated stubble. Water use was independent of stubble height. Previous research on the semiarid Prairies found that seeding into 12 inch...
