1. With phosphorus, ultimately the form you apply is less important than the amount you apply. Crop nutrition specialist Rigas Karamanos used the graph below to show the chronic under-application of P year after year.
A well-managed, systematic approach is the best strategy for bringing cleavers under control.
Seeding in March is way outside our sphere of experience, so even if the fields could be seeded, waiting until late April or May is still recommended. We still have lots of winter left for a potential cold and snowy snap — as demonstrated this week in many regions.
Know your fields and your yield expectations. Soils where N rates have not kept pace with N removal will need to be built back up to increase their productivity. Here is a review of N product options and how they become plant-available…
The has protocols and objectives for 2016 and results from 2015.
Swings from cold to warm temperatures this time of year can increase the storage risk for canola. Warm exterior temperatures and cooler canola will increase the rate of moisture migration inside the bin. Please check your bins.

Soil surveys by the CFIA in 2015 found V. longisporum in Alberta, British Columbia, Manitoba, Ontario, Quebec and Saskatchewan. V. longisporum is related to V. dahliae, which causes wilt disease of potatoes and sunflowers, but V. longisporum symptoms in canola do not seem to cause yield loss at this time.
A big thank you to everyone who took the time to fill out the recent Canola Performance Trial (CPT) survey! Results are available through the attached PDF.
CropLife Canada and the Canadian Honey Council have introduced a smartphone-based app to help facilitate communication between beekeepers, farmers, and sprayer operators.
Prairie Agricultural Machinery Institute (PAMI) plans to continue its evaluation of best practices for summer storage of canola in 2016. PAMI is looking for partner canola producers in Saskatchewan to assist with data collection.
Murray Hartman’s Science-O-Rama is April 6 at the Renaissance Edmonton Airport Hotel. The one-day meeting features 11 research updates. Registration is $75 plus GST. For more information and to register, .
Cover crops provide ground cover to avoid leaving fields bare. They provide weed competition, take up excess moisture, tie up nutrients at or near the soil surface so they’re not lost, and improve salinity. Nitrogen-fixing cover crops can increase soil nitrogen levels. Grassy cover crops act as “green manure”. All cover crops can reduce wind and water erosion of soil.
Canola Watch will provide regional updates when necessary. To do this, we need readers to update their free Canola Watch subscription to select the region that best suits their location. This takes four steps and about two minutes….
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.
