2. Check the density and condition of the stand
3. Estimate yield potential and gross revenue
4. Determine replant costs, including seed and equipment
5. Evaluate cost, returns to see if replant is worth it
As you know, soybeans are a bushy plant and can often compensate for low stands. This makes spot-replant more feasible. But it’s important to critically evaluate if replant is even needed—in some cases soybeans can withstand lower stands than you might think. Don’t forget the damage that could occur from late planting dates, too. Check out the chart below from the University of Missouri to get a general idea of yield expectations, but be sure to check with your local agronomist, too. Alternatively, corn should not be interseeded with already-growing stands. The smaller plants can’t compete with larger plants, causing them to underperform and steal yield from the larger plants. Experts recommend tillage or herbicides to terminate corn stands. “Tillage is most effective if the surviving plants are emerged,” says Brent Tharp, Wyffels Hybrids agronomy and product training manager. “you need to work it deep, at least 3 inches at an angle, to tear out the plants.” If you do choose to use a herbicide to kill the plants check plant-back restrictions before coming back in with seed. In addition, certain trait stacks might limit your herbicide termination options.
