Lack of crop diversity can increase the density of pests in a field. The higher the population of a pest in a field, the higher the risk of developing resistance to the pesticides (herbicide, fungicides or insecticides) used for controlling the pest in those fields…

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…

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…

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…
