Scouting soybeans is a giant a part of any Ontario agronomist’s yr. Emergence, a constant plant stand, and seeding depth are the first few issues to scout for in the subject.
Ryan Benjamins, who owns and operates Benjamins Agronomy Companies, offers suggestions for scouting soybeans and what to think about additional alongside in the rising season, on this Soybean Faculty episode.
“It starts with emergence and the number of healthy plants that have emerged per acre, and those come back to whether we need to do a re-plant or not,” says Benjamins.
From a plant inhabitants perspective Benjamins says that soybean is usually over-seeded. In the subject that Benjamins and Tobin are in — a clay-loam soil and a no-till system — over 170,000 seeds per acre had been seeded. “In this situation, as long as we have a consistent stand, over 100,000, we’re not going to do anything,” he says.
In the video, you’ll see a nifty trick that Benjamins makes use of to measure seed depth. Catch the full dialog between Benjamins and subject editor Bernard Tobin, story continues beneath:
For seeding depth, Benjamins mentions some analysis that OMAFRA soybean specialist Horst Bohner has finished that signifies the shallower the higher for soybeans, so long as it’s seeded into moisture. Soil moisture can actually dictate how deep to seed and it’s additionally essential to notice the situation of seedbeds at the time of planting in order that different points might be recognized in consequence.
“Certainly beans that are deep, I think in this field, they’re coming. The shallow ones, we’ve had rain, they’ll germinate and will likely come too,” says Benjamins. To do a stand depend, Benjamins recommends selecting a couple of spots and utilizing a hula-hoop or measuring six ft of row and utilizing that as a multiplier.
Weed management may also be assessed at the moment of yr and the typical, IP soybean subject that the duo is in required a pre-seed burndown after which a residual herbicide.
“We just know, even in dry years, we get a lot better weed control with that herbicide down, than trying to do everything and target ten different weed species post-emerge that are germinating at multiple times throughout the year,” says Benjamins. “Even if we get only 80 per cent weed control here, we’re set up to have a lot cleaner field by starting clean.”
