The safest method for seed-placed fertilizer is to put nothing with the seed. However, with low-medium soil test results, it’s often beneficial to put ammonium phosphate with the seed at a safe rate, and put all other fertilizers in a band away from the seed row.
The first two weeks of May are the ideal time to seed canola, based on long-term yield results from the Prairies. This has been shown in Canola Council of Canada research as well as crop insurance results.
Growers uncertain about which canola seeding rate to use should start with 5 lb./ac., then tweak. See the full article on this topic.
What nutrient SHOULD go in the seed row? Which nitrogen product definitely should NOT go in the seed row? What conditions improve the safety of seed-placed fertilizer?
Seeding can begin fairly soon after a burnoff — but take note of the weeds present.
In dry soil conditions, growers may be tempted to seed deep enough to reach moisture. This is not necessary in late April and early May, and may create more harm than good. The common recommendation to seed no deeper than 1” still applies. Here’s why…
Residue management to improve canola seed placement is best done in the fall with a well set combine and, if necessary, with harrowing. Residue issues in spring are more difficult to manage, given that straw tends to be cool and tough. Waiting for sunny and warm conditions will allow straw to break up and spread, improving results from harrowing.
The key with fertility decisions is to apply all of the 4 Rs — right fertilizer source at the right rate, at the right time and in the right place. Missing even one R reduces the yield response from the fertility investment. Make the most of your fertilizer investment. At the CanoLAB fertility station, attendees had a chance to ask …
Early seeding usually improves canola yield potential and quality, in large part because earlier crops tend to flower before the hottest days of summer. But the yield benefits of early seeding depend on survival of a sufficient plant population — ideally 7 to 10 plants per square foot, and a minimum 5. An early-seeded crop that is thin and uneven …
While growers wait to hit the fields, this is a good time to pull out the drill and give it a good inspection. A large flat concrete pad is ideal for leveling.
