Some growers are already doing soil tests and making fall fertilizer applications. While this may not be the ideal timing for soil tests of fertilizer applications (closer to freeze up is better), this timing may satisfy a number of other issues, including custom soil-sampler availability, wanting test results before fall application, and checking to see if current soil nutrient levels…

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

For results to be as close as possible to the situation next spring, the ideal time to take fall samples is when soil temperatures drop below 10°C and as close to freeze-up as possible…

Western Canada has a short growing season. Crops in Western Canada start to take up nutrients early and uptake escalates quickly. For these reasons, the ideal timing for fertilizer application is at seeding. This saves an extra pass over the field and ensures that the expected fertilizer requirement is in place when the crop needs it. But there are times… -
We had two questions in the past week about top-dressing fertilizer after seeding. 1. How early is too early to top dress? 2. Does adding S stabilize N against losses?…

Each farm will base its nitrogen application practices on time, labour, equipment and cost. Often losses in efficiency in one area can be compensated for by improvements in another. The "best" nitrogen (N) system is not universal, but will depend on the major limiting factors on each individual farm. Here are key points to consider for the six most common…

The combination of warm weather and moist soils is almost ideal for losses. Growers may want to reassess the nutrient situation with a time-of-seeding soil test, then top-dress if amounts are less than expected…

Given the warm temperatures and moist soil conditions, the ideal time for fall soil samples may still be ahead of us. For results to be as close as possible to the situation next spring, the ideal time to take fall samples is when soil temperatures drop below 10°C and as close to freeze-up as possible…

The key strategy of fall fertilization is to store nitrogen over the winter in the ammonium form – which is held on clay and organic matter – and is referred to as stabilized N. To keep nitrogen in this stabilized ammonium form and protect it for crop use next year…
