• Nitrogen is quite mobile in the soil, and amounts can fluctuate year to year and depth to depth. Although some growers have success by using removal rates and target yields when making N decisions, a soil sample can be a great indicator and a good way to ensure intended rates aren’t too high or too low. When determining how much…

  • Microbial processes in the soil slow down as temperatures cool. Therefore, sampling late in the fall will provide a close representation of nutrient levels at seeding next spring. Fall soil tests give growers time to process samples and get results and recommendations. That information can be used to develop a fertilizer program for this fall or next spring…

  • A risk with fall application of nitrogen fertilizer is that denitrification and leaching will remove a large percentage of the applied fertilizer before seeding starts in the spring. This is a legitimate risk, as losses compared to a time-of-seeding application can be 30-40% in moist and warm conditions. To reduce this risk…

  • Green blues. By October, getting crop off becomes the priority. Green seed is unlikely to turn anymore unless a lot of moisture (snow?) comes, in which case harvest may be delayed until spring. Cool days, but hot bins. Canola binned hot will retain that heat for weeks and likely months, with the risk of storage losses rising with each passing…

  • Take fall samples when soil temperatures drop below 10°C, or cooler. Because microbial processes in the soil slow down as temperatures cool, sampling late in the fall will provide a close representation of nutrient levels at seeding next spring. The cooler the better when sampling, but you want to make sure you can still get the probe down 24”. Submit…
