Top dressing fertilizer usually occurs after emergence, often as a response to increased yield potential or as a remedy for noticeable deficiency symptoms. However, growers are looking at top dressing this year as a logistical aid in getting the crop seeded faster. Here are some agronomy messages to help in your decision making…

In an Alberta study, fertigation was put on at three different stages — 5-leaf, bolting, and flowering — and then compared to plots where all nitrogen was applied at the time of seeding. The study has only one year of results, and so far they show that with canola, fertigation is — at best — equal to the treatment that…

This graph shows that a higher seeding rate that will ensure a stand of at least 60 plants per square metre (6 per square foot) will mature a lot earlier than a stand with 20-40 per square metre. A higher seeding rate is just one way to reduce the days to maturity for a late seeded canola field…

Good soil moisture may encourage some growers to increase planned nutrient rates to capture an increase in yield potential. However, before increasing fertilizer rates, you may want to make sure you can get timely delivery of that extra fertilizer. Talk to your supplier. You don’t want to run out of fertilizer and still have 15% of the crop to seed…

Canola profits tend to benefit most from a nutrition plan that includes nitrogen, sulphur and some seed-placed phosphate. But what about potassium? Or micros? The Canola Council of Canada’s Ultimate Canola Challenge (UCC) will continue for 2014, with 15 sites across the Prairies. UCC will include many of the same comparisons as 2013, looking at various micronutrient treatments to see…

This figure show the yield response of hybrid canola to applied and soil nitrogen. The blue line is what matters when assessing the return on investment and your risk assessment with regard to nitrogen. Here’s how to read the figure…

The 4 Rs, as described by the Canadian Fertilizer Institute and other crop nutrition organizations, are the right fertilizer source at the right rate, at the right time and in the right place. The 4 Rs will help you make the most of your fertilizer investment. Here are the three basics of canola crop nutrition…

One goal in the Canola Council’s new strategic plan is to reach an average yield of 52 bu./ac. by 2025. This, along with acres holding at around 2012 levels, will achieve the production target of 26 million tonnes — which is the forecast market for Canadian canola by 2025. Here are five keys to achieving the yield target…

Nutrient reserves vary from field to field, and from zone to zone within each field. This has encouraged some growers to create different blends for each field, and to use variable rate application to adjust rates based on management zones within a field. A soil testing program is essential to determine the right blend for each field. The question, from…
