Digging into Research
Phosphorus (P) fertilization did not increase seed yield, regardless of P rate, P placement or Olsen soil test P level, except for one out of 28 site-years. High rates of seed-placed P reduced stand establishment at 5 of 28 site-years. Limited research had been conducted on...
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...
Average faba bean nitrogen (N) uptake was 205 pounds per acre (230 kg N/ha) and phosphorus (P) uptake was 23 lbs/ac (26 kg P/ha). Overall, faba bean fixed 88% of its nitrogen from the atmosphere. Faba bean is a high-protein pulse crop that has the potential...
In this controlled environment chamber study, struvite and MAP had similar crop biomass yield and phosphorus (P) uptake in canola. There was no difference in canola germination between MAP and struvite, or opener spread of 1 inch or 3 inches, or fertilizer rate up to...
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...
Vegetative filter strips, or buffers, were effective at retaining phosphorus after a runoff event during the growing season but not in the spring or fall outside the growing season. The findings of this study suggest that vegetative filter strips are inconsistent and not likely to...
Research was conducted in southern Alberta to look at the effects of long term feedlot manure application on irrigated barley yield, macronutrient supply, earthworm abundance, and water extractable carbon in a clay loam soil. Two to 3 years after manure application was stopped, barley silage...
Placing phosphate fertilizer in the seed row has its challenges because seed damage can occur at fairly low rates. Rather than short the crop with a low seed-placed rate, this study found that the full recommended rate placed outside the seed row is the better...
While this Saskatchewan study did show a yield response for foliar-applied phosphorus (P) when compared to a control without any P fertilizer, the best practice is still to meet crop needs with fertilizer applications before or at the time of seeding. This study evaluated the response...
On sites testing low in nitrogen (N) fertility, flax yields were 39% higher with rates of 90 lbs. N side-banded per acre. Flax response to phosphorus (P) averaged 7% and rates of no more than 18 to 36 side-banded P2O5 per acre were justified. Phosphorus...
