Canola School: Starter fertilizer considerations


With canola costs the place they’re at, producers need to hit these optimum yields. There are just a few hurdles to beat this yr although, as excessive fertilizer costs and dry situations may restrict starter fertilizer charges.

On this Canola College episode, Kara Oosterhuis is joined by Jack Payne, develop crew advisor at Federated Co-operatives Ltd., on how expertise may also help make these powerful fertilizer decisions.

“For nitrogen, the standard recommendation has been to use 2.75 to 3.2 pounds of nitrogen per bushel of yield,” says Payne. “But, there’s no one number because it depends on your situation, depends on your soil, and depends on your area in terms of moisture, so what coefficient you use really comes from your own experience or from your agronomist.”

Within the video, Payne provides the instance of making use of 40 to 60 kilos of N (for the season, not with the seed). “That first 40 to 60 pounds is going to give you the biggest bang for the buck or the best return because it’s on that initial part of the yield response curve, where it’s the steepest,” says Payne. As soon as extra product is utilized, the yield response curve begins to plateau.

Watch the total video to listen to extra from Payne, and subject editor Kara Oosterhuis, story continues beneath video:

On the subject of sulphur, it’s an vital nutrient for canola, and when inserting it within the seed-row, producers must pay shut consideration to charges.

Payne says that one of many standby suggestions comes from Dr. Ross McKenzie, former soil and crop analysis scientist with Agriculture and Agri-Meals Canada: if the take a look at exhibits 15 kilos of sulphur or much less within the high six inches of soil (the A horizon), apply sulphur, no matter what’s within the second depth (the B horizon).

Watch out for the salt impact when making use of ammonium sulphate with seed, and Payne advises to again off the speed, or go for an elemental sulphur product with small particle dimension, because it’ll oxidize sooner.

Dry situations are prevalent throughout a lot of the Prairies this yr,  so there are just a few nutrient administration choices to make. Payne says to not modify the goal yield. Water is the primary issue that drives yield potential so the million greenback query will probably be whether or not it rains or not.

“If you’re hedging that it’s dry and it’s going to continue to be dry, maybe you want to dial back your rates to hedge your bets,” says Payne. Then again, setting the bar low will decide the place you max out in your yield. It’s a big gamble, identical to a number of different choices in farming.

For phosphorus, it’s actually vital to observe the seed-placed charges. Payne says that over time there hasn’t been sufficient phosphorus utilized to canola crops although. Canola will use virtually a pound of phosphate per bushel of yield. It’s a double-edged sword this yr although, as a result of the the worth of phosphate fertilizers is excessive this yr.

Lastly, boron has been recognized these days as poor on some soil take a look at experiences. Foliar merchandise are good for topping as much as deal with the symptom, however think about making use of boron to soil too, if exams indicated it’s missing.

Payne’s final piece of recommendation is to maintain good fertilizer information by beginning with a soil take a look at within the fall after harvest, and, primarily based on that end result, understanding a plan.
