  • The right nitrogen system for you

    Fertility

    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 systems.

  • Fertilizer applications in November

    Fertility

    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.

  • Soil sampling in November

    Fertility

    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.

  • How to reduce fall N fertilizer losses

    Fertility

    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…

  • Timing and depth for fall fertilizer

    Fertility

    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.

    Sweep netting begins for lygus and cabbage seedpod weevil.

    By this stage of the season, flea beetle and cutworm risks are lower because crops are bigger and these two insects are in natural seasonal decline. Adult flea beetles have laid their eggs and are dying. Cutworms are pupating. We’re now moving toward sweep net timing for lygus and cabbage seedpod weevil.
