  • Tough canola can heat quickly

    We heard a report this week of tough canola starting to heat after just two days in the bin. This is a good reminder to put canola on aeration right after harvest, especially if it’s tough or hot or both. Waiting a couple weeks until all the combining is done may be too late.

  • When to spray weeds in the fall?

    Fall is a good time to control perennial and winter annual weeds, but spraying immediately after harvest may not provide the best results.

  • The right time for fall soil testing

    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.

  • Timing and depth for fall fertilizer

    Fall fertilizer is best applied as close to freeze up as possible to balance two objectives: (1) allow soil to seal over the band and (2) reduce losses due to high microbial activity in warm soils.
