Five questions on the mathematics of soil sampling and analysis of results.
Good jobs for an open fall:
- Collect soil samples for nutrient analysis
- Count stems per square foot to help with seed planning
- While counting stems, check them for verticillium stipe
- Control perennial and winter annual weeds
- Apply nutrients
- Harrow to spread residue uniformly
Turning on aeration fans shortly after harvest will remove any moisture that has respired from the seeds – which commonly occurs after harvest. Aeration also cools the grain and evens out the temperature.
The Canola Council of Canada agronomy team encourages canola growers to choose hybrids based on the opportunities and challenges in each particular field. This approach is seen as one way to improve productivity and profitability of the crop. Here are some scenarios describing how a farm might benefit from adopting this strategy….
Soil sample the fall after canola harvest or the spring immediately following. This gives galls time to break down and release spores. If sampling this fall, target fields that are going into canola next year…not fields that were in canola this year
Growers who participate in the Canadian Grain Commission’s Harvest Sample Program get an unofficial grade, including dockage, oil content and chlorophyll (green) content for their canola. The CGC also uses the results to estimate the overall quality of Canada’s canola crop.
