  • Rain – Some Needed Some Not

    Rain – Some Needed Some Not Rainfall was received in many areas across the Prairies last week. Amounts ranged from a few tenths to as much as 3 inches in southeastern Manitoba. Excess moisture is now limiting field operations in many parts of Manitoba. Many areas in Saskatchewan and Alberta that were in need of […]

  • Seeding Nearing Completion

    Across the majority of Saskatchewan last week, canola seeding continued and is now nearing completion. Some of the earliest seeded fields are beginning to emerge. Around Leader, Rosetown, and Kindersley areas, producers have stopped seeding canola because of poor soil moisture. In Alberta, canola seeding is also nearing completion and earliest seeded fields are emerging. […]

  • Canola – Winter Wheat – Canola Rotation?

    In Manitoba, a significant amount of winter wheat acres planted last fall were winterkilled. Manitoba Agriculture, Food and Rural Initiatives (MAFRI) estimates that 80% of the winter wheat in the Red River Valley and approximately 15% of acres in the rest of Manitoba will be reseeded. Some producers are considering seeding canola into the dead […]

  • Sun/Warmth Continues to be Evasive

    Cool daytime and cold nighttime temperatures prevailed across the Prairies last week. Many areas reported frost with temperatures dipping to minus 7 oC. Near Trochu, Alberta temperatures as low as minus 8 oC to minus 10 oC were recorded. Very little canola had emerged last week and so minimal reseeding was necessary. Many fields that […]

  • Give the Sun a Chance

    With some areas having canola seeded for almost four weeks, the integrity and viability of the seed has started to be questioned. Much warmer temperatures (mid 20°C’s) are forecast for the coming days. Give the soil time to warm up (three to five days) before making any evaluations or decisions. Soil temperatures will lag behind […]

  • What’s Taking so Long?

    Soil temperatures remain cool causing seeded crops to germinate and emerge very slowly. The following maps show growing degree days (GDD) that have accumulated thus far: http://www.agr.gc.ca/pfra/drought/prtgdd_e.htm In Manitoba, accumulated GDD are compared against a historical average at: http://www.gov.mb.ca/agriculture/climate/wad00s00/cropwxrep.pdf The number of days to 50% germination is a useful benchmark as the first half of […]

  • Get Down and Dirty

    Apparently there is growing concern that crops are taking too long to emerge and will have to be reseeded. Those decisions cannot be made without getting down on hands and knees to determine what the seed is doing. This spring, in some areas, it is taking seven days before the seed coat even begins to […]

  • Seeding Tips to Hasten Maturity

    Late seeders and reseeders – give your canola the best possible start. Try to employ techniques that will encourage rapid and even emergence. Target a consistent seeding depth of ½” to 1”. It may be necessary to slow down to achieve this consistency. Because of changing soil conditions and the potential for mechanical issues with […]

  • Frost on Canola – Don’t Assume the Worst

    Freezing temperatures were again widespread last week and over the weekend in many parts of the prairies. This may prompt canola growers to consider reseeding. However, resist the urge to reseed immediately, as recovery may turn out to be better than expected, especially if seed has not yet germinated or the young seedlings have become […]

  • Keep Good Records

    Now is the time of year to have a pen and paper handy. Keep good records. Write things down while details are still fresh. Note seeding date, rate, fertilizer applied, herbicides applied, etc. Always keep a seed sample and the blue seed tag from each variety and seed lot sown. Store samples in a paper […]

  • Spraying Tips

    Water quality is the key to achieving proper performance of many herbicides, particularly with glyphosate and many grassy weed products. The following link provides more information on spray water quality: http://www1.agric.gov.ab.ca/$department/deptdocs.nsf/all/agdex7573 Custom applicators (and growers in general) should double check to ensure the right product is being applied to the right field. Ensure legal land […]
