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...
In this 2-year study, there was no significant benefit of a urease inhibitor, with or without a nitrification inhibitor, on canola and wheat N removal, N uptake, nitrogen use efficiency or yield. These inhibitors also did not significantly reduce the amount of leached nitrate in...
Nitrification-inhibitor products – either alone or in combination with an urease inhibitor – reduced N2O emissions by 38% to 43% compared to untreated urea in spring wheat in southern Manitoba. However, there were few yield or grain protein benefits to using the EEFs products. Environment and...
Starter phosphorus (P) and zinc (Zn) fertilizer increased early-season growth, plant height, P concentration, and uptake of P and Zn in plant tissue, relative to the unfertilized control. In some cases, starter fertilizer reduced days to maturity and grain moisture content. The largest responses were...
Canola yield increased by up to 40% with increasing N rate up to 134 lbs/ac (150 kg/ha) pre-plant (i.e. close to seeding) application via broadcast or banding. There was no significant difference in yield between pre-plant only N application and a split pre-plant plus top-dress...
In western Canada, no-till improved wheat yield by 7%, canola by 10%, and legumes like beans, peas and lentils by 9% compared to conventional tillage. These higher yields provide higher carbon inputs into the soil to help increase soil organic carbon and reduce greenhouse gas...
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...
The combined application of Cu + Zn had a significant negative effect on wheat yield grown under phosphorus (P) deficient soil conditions on a Dark Grey Chernozem Tisdale soil. This indicates that if Cu and Zn deficiencies are going to be corrected, P fertility should...
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...
Benefits of a pea-cereal intercrop for forage production included nitrogen (N) fixation and transfer of fixed N from the pea to the cereal component while maintaining dry matter yields equivalent to a cereal monocrop. Intercropping pea with a cereal crop for forage production is gaining interest...
