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...

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...

Liquid UAN with an urease inhibitor in a split application optimized N use efficiency, grain protein, yield and yield stability. EEFs did not affect greenhouse gas emissions. With the development of enhanced efficiency fertilizers (EEF), winter wheat growers have the opportunity to improve nitrogen use efficiency...

On dryland sites that have low to moderate productivity, winter wheat growers should band all N at planting to ensure maximum grain yield and protein content. For irrigated winter wheat production or in dryland areas with high yield potential, a split application of fall banded...
