    Dry conditions concerning. Consider soil moisture reserves when setting yield targets and fertilizer rates for 2012. A lot can change between now and seeding, and growers have “never lost a crop in February,” but if moisture does not improve, yield potential should be reassessed when setting targets and budgets. Hot topics at trade shows and […]


  • How much fertilizer does canola need?

    When setting fertilizer rates, it helps to know your target yield and how much fertilizer canola needs per bushel of yield. Some of that will come from soil reserves and from organic matter. The rest has to be applied as fertilizer.


  • Trade show season brings out the novel products

    Canola plants, like any other plant, need many different nutrients and rely on naturally-occurring hormones to grow and produce a good yield. Limitation on any of these may reduce yield potential, but in most cases, the biggest return on investment comes from the nutrients required in the greatest quantities, such as nitrogen, phosphorus and sulphur.


  • Warm spells put stored canola at risk

    With a warm winter, the central core of a bin may not freeze. It may take just a few warm days to get canola core temperatures rising again. A stretch of warm weather in February and March could make stored canola unstable and lead to unexpected heating


  • Will we have any winterkill of insects?

    In general, overwintering mortality is not a major factor in reducing insect populations, but we know of a few important exceptions:


  • Tips from excess moisture meetings

    Nutrient carryover is a common question from growers with unseeded acres. The standard answer is: Nitrogen is always variable throughout a field, and after a wet year without a crop, reserves might actually be better on the hilltops than in low spots. In low areas flooded for long periods, lack of oxygen limits microbial breakdown of organic matter. Therefore nutrients made available through mineralization will be lower than expected in these low-lying areas. Leaching of nitrogen and sulphur and de-nitrification of nitrogen will be higher in those areas as well. Test saturated areas separately.


  • Glyphosate resistant kochia found on Prairies. Now what?

    Read on for tips to reduce the risk of selecting for resistant weeds on your farm.
