Blackleg resistance is starting to show cracks in some areas where tight canola rotations have become normal practice. This is a reminder that the long-term viability of genetic resistance does require some rotation management on the growers’ part. This may be particularly true for clubroot resistant canola varieties, which have become a key clubroot management tool for growers with heavy…

New research shows a statistically significant increase in crop damage by root maggots in continuous canola rotations. This increased damage coincided with reduced yields…

The success of herbicide tolerant canola technology to control weeds is one reason why canola rotations have tightened. Economical weed control has increased canola profits. But the reduction in crop diversity can allow some weeds (and insects and diseases) adapted to growing with canola to increase in density and intensity. This places increased pressure on the chemical tools used to…

Taking a risk on a tight canola rotation may be the better economic decision for their farm that year. But having some diversity can help manage economic risk in the long term…

A good time to test soils. Hold off on tillage. The seed decision. New insights for canola storage. Please fill in our Canola Watch survey…

Fall is a good time to do soil tests. Growers may have a extra few hours to take samples, unlike in spring. And with results and recommendations in hand before winter, growers have more time to plan their fertilizer programs for 2012, to order fertilizer, and to take advantage of reduced pricing opportunities that may occur…

Soil organic nitrogen levels in the top 6” of soil can range from 2,500 to 7,500 pounds per acre. Around 1% to 3% of that soil organic N mineralizes and becomes available for plant uptake each year. If soil has 5,000 pounds of soil organic nitrogen in the top 6”, it could provide anywhere from 50 to 150 pounds of…

Growers have made great strides in advancing no tillage and conservation tillage practices. General benefits include reduced fuel use, reduced soil erosion, higher soil moisture reserves (which are welcome most years), and a general increase in profitability. Any return to tillage, even if only one field or across the whole farm for only one year, should be weighed carefully…
