Canola generally needs nitrogen, phosphorus and sulphur fertilizer each year. A small percentage of fields will also benefit from a potassium application. The following article suggests what canola needs and what soil and crop residue could provide. The rest will come from fertilizer…

When well-designed research studies are done for micronutrients in canola, results show little if any economic benefit…

One challenge with boron is the hot water extraction (HW) soil test commonly used to test boron levels does not seem to be a reliable indicator of available boron. A 1999 study by Rigas Karamanos showed no relation between HW boron levels and canola yield, as the graph shows. Yet soil analysis continues to use the HW test for boron… -
This diagram from IPNI shows where deficiency symptoms are likely to show up on a plant. Nitrogen is mobile, so with an N shortage, plants will move N to new parts of the plant. Therefore deficiency will show up first in older leaves… -
The UCC site that will be featured for Saskatchewan is located near Meadstead. The site was seeded with the Dekalb 74-44 variety on May 14th, 2015 at a rate of 5.3lbs/acre. The fertilizer was 130-40-0-30 of actual nutrient as liquid sidebanded with 0.3lbs/acre of boron in liquid form… -
As part of UCC 2015, the CCC agronomy team is looking for 12-15 growers from across the Prairies to test boron in field-scale trials in 2015…

Canola needs a little bit of boron, and most Canadian Prairie soils have enough to meet this demand…

If a grower decides to try something new, find a uniform field, try one product at a time and leave an untreated check, ensuring both treated and untreated areas are accurately measured for final yield and grade so a true economic comparison can be made. In reality, some products may provide a good payoff for the price, but that payoff…
