Agronomist says nutrient deficiencies are evident in Ohio corn crop


A WinField United agronomist says the corn crop in Ohio is experiencing nutrient deficiencies.

Ohio-based Joe Rickard says wet conditions have caused higher than normal deficiencies in boron.  

“All the growers have noticed it’s been wet, so that boron that has been in the soil has leached away and that’s why we’re seeing some of these deficiencies this year,” he says.

About 98 percent of corn tissue samples taken at the V4-8 growth stage in Ohio this week were deficient in boron.  

He urges growers to work with their local agronomist to address these issues by taking tissue samples.

“They can come out and pull that tissue sample and usually it takes about two to three days,” he says. “Then we can make an in-season application or management decision based on that tissue sample.”

Rickard tells Brownfield boron deficiencies are widespread across the corn belt…

“Indiana, Illinois, Minnesota, Nebraska, Wisconsin, and the Dakotas are all seeing or exhibiting some sort of boron deficiency,” he says.

Nearly 92 percent of samples in Ohio were also deficient in zinc, 68 percent were deficient in phosphorous, and 67 percent were deficient in manganese.
