Growers can expect to see some nitrogen loss from extended heavy rains, probably in the range of 20-50%. Before top dressing, wait to see how the crop recovers from saturated soils before investing any more in fertilizer. Don’t do anything while soils are still wet — roots cannot take up nutrient when soils are saturated. Applying nutrient direct to leaves…

Nutrient and fungicide top dress treatments have been promoted to help heal and restart canola after hail. We don’t have published studies on using these or any treatments for this purpose in Western Canada, so it’s buyer beware. Leave a check strip to see if they improved yield. For products that require foliar uptake to work properly, severe hail damage…

Fertilizer dribble options for the sprayer: 1. Streambars or dribble bars are long bars — 12” to 15” or so each — with 4 holes along the length. They attach to each sprayer nozzle point, with the bar designed to reduce the distance between streams. Advantage: Streams drop straight down so spray patterns are unaffected by boom height. Disadvantages: They…

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…

Give the brand new online Canola Diagnostic Tool a pre-season test drive at www.canoladiagnostictool.ca. Start with a problem scenario that you encountered in a canola field in 2012, and work through the tool to see what potential causes it provides. Read the cause descriptions and “ways to confirm” to determine which cause is most likely…

If you want to use soil test results to see whether this year’s crop had enough nutrients, sampling now would be the better option. To plan for next year, soil samples taken closer to freeze up are a more accurate estimate of levels next spring…

A number of new fertilizer products are on the market, including seed coatings that contain small starter amounts of macro- and micronutrients. On canola seeded at the equivalent of 5……
