Starter P side-banded at planting is beneficial for corn growth, maturity, grain yield, and grain moisture compared to fall deep-banded P. Strip-till corn performed similar to conventionally planted corn, and is a promising practice for soil and moisture conservation in southern Manitoba. Strip-till equipment moves residue...

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...
