For every 5 pounds of nitrogen a canola plant takes up, it needs 4 pounds of potassium. Most Prairie soils still have adequate potassium reserves, but tight canola rotations and high canola yields will be mining the soil and deficiencies are starting to show up on some farms…

Seed treatments are, for the most part, very effective against canola seedling diseases fusarium, pythium and rhizoctonia. But plant pathologists expect that continued tight canola rotations will select for seedling disease pathogens that will overcome these treatments…

The key messages from this station: —Keep an open mind when scouting a field for problems. Symptoms can have many causes, and it can be a costly mistake to jump to conclusions before considering all possibilities. Many probable causes were discussed ranging from diseases to insects when describing sick or non emerging plants. —Environmental stresses like heat during bolting through…

What is the ideal bin for canola? How do I know when to start the fans and shut them off? Do I need bin monitoring cables? Is my aeration fan strong enough? Can I put canola in bags? Industry experts will help you answer these questions and many more at the hands on Canola Storage Clinic at the Keystone Centre…

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……

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…

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…

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

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…
