• UCC: 2017 results, 2018 plan

    January 17, 2018

    UCC field-scale trials in 2016 and 2017 compared the farmer’s base nitrogen rate with a rate 25% higher. With all site years averaged, adding extra nitrogen did provide a statistically significant yield response, but the increased nitrogen did not always provide an economic return when compared to the base rate…

  • Timing and depth for fall fertilizer

    October 4, 2017

    Fall fertilizer is best applied as close to freeze up as possible to balance two objectives: (1) allow soil to seal over the band and (2) reduce losses due to high microbial activity in warm soils…

  • Early fall soil tests and fertilizer applications

    September 27, 2017

    Some growers are already doing soil tests and making fall fertilizer applications. While this may not be the ideal timing for soil tests of fertilizer applications (closer to freeze up is better), this timing may satisfy a number of other issues, including custom soil-sampler availability, wanting test results before fall application, and checking to see if current soil nutrient levels…

  • Top dress tips for nitrogen and sulphur

    June 7, 2017

    Western Canada has a short growing season. Crops in Western Canada start to take up nutrients early and uptake escalates quickly. For these reasons, the ideal timing for fertilizer application is at seeding. This saves an extra pass over the field and ensures that the expected fertilizer requirement is in place when the crop needs it. But there are times…

  • Fertilizer top dress: 2 questions

    May 31, 2017

    We had two questions in the past week about top-dressing fertilizer after seeding. 1. How early is too early to top dress? 2. Does adding S stabilize N against losses?…

  • The right nitrogen system for you

    March 2, 2017

    Each farm will base its nitrogen application practices on time, labour, equipment and cost. Often losses in efficiency in one area can be compensated for by improvements in another. The "best" nitrogen (N) system is not universal, but will depend on the major limiting factors on each individual farm. Here are key points to consider for the six most common…

  • How to reduce fall N fertilizer losses

    October 13, 2016

    The key strategy of fall fertilization is to store nitrogen over the winter in the ammonium form – which is held on clay and organic matter – and is referred to as stabilized N. To keep nitrogen in this stabilized ammonium form and protect it for crop use next year…

  • Keep up to speed with the UCC

    June 1, 2016

    Nitrogen is the theme for 2016. Follow along the UCC journey on Twitter with the #CanolaUCC hashtag and on Instagram at ultimate_canola_challenge…

  • Nitrogen review: Sources and plant availability

    March 18, 2016

    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…
