Be Ready for Anything This Planting Season

You can’t always predict the weather; but you can put plans in place so you’re ready to plant in all conditions

Poor stands often result from failing to adjust equipment to fit soil conditions. Adjust row cleaners, closing wheels and down pressure from field to field.

There are few mistakes that you can’t overcome, given enough time. But problems at planting time set the stage for an entire season’s worth of trouble.

Many, if not most, planting problems result from failing to adjust practices and equipment to fit soil and weather conditions, says Farm Journal Field Agronomist Ken Ferrie. Since you can’t know what the weather will do, you have to plan for various scenarios.

What if it’s dry? Ferrie has one rule: Don’t plant corn into dry soil, hoping to "rain it up."

"Putting corn in dry soil, and not having it germinate in timely fashion, can be a disaster for your stand," he says. "In 2012, most problems with dry soil resulted from doing spring tillage too far ahead of planting. That lets the soil dry out. Don’t let your soil finisher get too far ahead of the planter in a hot, dry spring."

In a dry situation with conventional tillage, use row cleaners to push away clods in front of the planting units. "If you crush clods with your depth wheels, you’ll put dry soil around the seed," Ferrie says. "Use your row cleaners as a clod roller."

In either no-till or conventional tillage, use row cleaners to move residue out of the way. "Normally, a little residue is no big deal," Ferrie says. "But if it’s dry, residue tucked into the seedbed wicks moisture out of the furrow, away from the seed."

Running out of planting moisture in no-till is rare, but it can happen in sandy soil or if you fail to kill a cover crop on time, Ferrie notes. "It can happen when strip-tilling in coarse soils, if you are not timely with your planter," he says. "In strip-till, you may have to go off the strip and no-till the seed beside it."

In tough conditions, with no rain in the forecast and you know it will be even drier in 10 more days, use your row cleaners to move away the dry soil. Hopefully, this will get you closer to some moisture where you can place the seed, Ferrie advises.

This carries risk, though. "If you applied a pre-emergence herbicide, there will be no herbicide left in the row," Ferrie says. "Have a plan in place to control weeds in the row."

If you "plow down to moisture" in strip-till or conventional tillage, you will actually be planting in a valley. "If the weatherman turns out to be wrong and you get a toadstrangling rain before the corn comes up, the corn will get buried and you’ll have to replant," Ferrie says. "But at least you’ll have moisture to replant in."

What if it’s wet? Unless you own a crystal ball, you need a plan for wet weather, too. "Don’t mud a crop into cold, wet soil unless you’re running up against the crop insurance date because of prolonged cool, damp weather," Ferrie says.
