Early spring is a nice time to take a look at how effectively residue was unfold from the earlier harvest. Having uniform residue administration could make all of the distinction for seedbed preparation, seeding, and getting that uniform canola stand.
On this Canola Faculty episode, Leighton Blashko, senior technical specialist with BASF joins Kara Oosterhuis within the discipline, to speak residue administration methods.
It comes all the way down to monitoring the uniformity of straw in a discipline. “If you have a uniform seedbed, you’re going to have a uniform stand,” says Blashko.
How a lot straw is there, if it’s unfold uniformly, and the scale of the residue can all have an effect on the seedbed, which might have an effect on plant institution of the crop.
“If you’re able to have a very uniform seedbed, you’ll then have the best chance to place every seed in a nice, perfect area, where it has a perfect microclimate to be put at the perfect depth, and to germinate, emerge, and produce a healthy crop,” says Blashko.
If in case you have uniform stand institution, you’re capable of time issues correctly — herbicides, fungicides, or a resolution at harvest like a seed-colour change measurement for swath-timing or straight-cutting. (Story continues beneath video.)
Discipline-by-field make a resolution on effectively that residue is unfold. If the mix did a good job, then there’s nothing to fret about, however for those who don’t have uniformity, there’s a few choices. Heavy harrowing simply to unfold out the residue is one possibility.
Extra aggressive vertical tillage or utilizing high-speed discs has positives and negatives — managing extra moisture in wetter areas of the province or the danger of dropping soil moisture in dry areas.
If in case you have any potential clubroot within the discipline, then tillage of any type in all probability isn’t the most suitable choice, as you’ll be spreading spores throughout a complete discipline, says Blashko. The much less aggressive you’re will maintain clubroot spore unfold minimized.
Lastly, measure the success of your residue administration efforts by following-up after seeding and checking on plant stand uniformity.
