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...

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...

Applying monoammonium phosphate fertilizer using broadcast without incorporation, especially at rates above that normally recommended for a single season, is not recommended due to the increased potential for P export offsite in spring snowmelt runoff. Phosphorus from non-point sources such as snowmelt runoff is a contributor...

In this study, foliar phosphorus (P) application was unable to substitute for seed-placed P. Overall, foliar P had a marginal effect on grain yield, P uptake and seed nutritional value. Generally, little research has been conducted in western Canada to assess the potential of foliar-applied phosphorus...

For this study conducted in southern Alberta on irrigated and dryland plots, the precision planter with 12 inch spacing increased seedling emergence and plant stand density compared to an air drill on 12-inch spacing or precision planter with 20 inch spacing — as long as...
