combine harvesting soybeans Jennifer Kiel
YIELD DROP: Ohio’s soybean yield is forecast to be down 31%, while corn yield is forecast down 34% from last year’s yield. The projected yields on both crops are expected to be the lowest since 2008, according to USDA.

Ohio corn, soybean yields to be lowest in 10-plus years

Yields for both crops are expected to be more than 30% less than last year.

The late start to the planting season stunted growth in many corn and soybean fields across Ohio, and yields for both crops are expected to be the state’s smallest since 2008.

Last spring’s unrelenting rain caused shallow roots to develop in both soybean and corn plants because the roots did not have to reach far down into the soil for moisture, say crop experts with Ohio State University College of Food, Agricultural and Environmental Sciences (CFAES). Planting in wet soils also led to soil compaction, in which particles of soil became pressed together, reducing space between them and limiting the flow of water.

Then, summer brought little rain in much of the state, further hindering the plants’ ability to absorb water.

“The issues with corn this year, I think, are pretty widespread,” says Peter Thomison, a CFAES corn field specialist.

Ohio’s corn yield is forecast to be down 34% from last year’s yield; and its soybean yield is forecast to be down 31%. The projected yields on both crops are expected to be the lowest since 2008, according to USDA

Corn in some Ohio fields is at risk of fungal rot, which can cause stalks to break off below the ears, leading to harvest losses, Thomison says.

To reduce potential losses, corn growers should prioritize harvesting fields with stalk rot, because delaying harvest increases the risk of stalks breaking off, he says.

Southern Ohio worse off than northern Ohio

Corn and soybean plants in southern Ohio, south of Interstate 70, suffered higher disease rates than those in northern Ohio, says Harold Watters, a CFAES agronomy field specialist. For corn, the most common diseases this year are northern corn leaf blight and gray leaf spot; for soybeans, it’s frogeye leaf spot.

In some parts of the state, such as in portions of Union County, the lack of rain this summer will cut yields by as much as half, Watters predicts.

“2019 will test our bank accounts and our patience,” he adds. “For many, this year may bring in just about half the income they had last year. That means delaying purchases, reducing personal spending and asking the bank for more loans.”

The late start on planting corn and soybeans will mean that both crops could take longer to dry sufficiently in fields before they’re harvested, says Jason Hartschuh, an OSU educator in Crawford County.

“You’re going to see more soybeans harvested in November than normal. There will be some that are green as grass upon the first frost,” he says.

Drying crops with mechanical dryers not only adds time and expense, but the process also comes with some risks, Hartschuh says. Soybeans that get too hot can shatter. Also, being high in oil content, soybeans stand a risk of igniting and starting a fire. So, farmers have to weigh those risks, he says.

In talking to farmers in northwest Ohio, the region hit hardest by the spring rain that delayed or prevented planting, Hartschuh tries to put this year’s crop issues in perspective: “Remember, this is one year. You always have next year to look forward to.”
