ROCKVILLE, Md. (DTN) — If you find yourself wishing for a normal corn-growing season this year, Bob Nielsen has bad news.
“I think we actually need to redefine normal weather,” the longtime Purdue corn agronomist said. “Today, normal weather consists of an unpredictable number of unpredictable extreme weather events, each occurring unpredictably with unpredictable severity.”
Corn growers need to focus their energy on weatherproofing their fields, Nielsen told growers during Purdue’s virtual Crop Management Workshop held Jan. 28.
“When we get extreme weather, the negative effects of it are often amplified by other yield-limiting factors that may exist in the field,” he explained. Those include problems such as poor drainage and compaction, which can make a heavy rainfall or a flash drought more damaging than they need to be.
“While we cannot control the weather, if we can identify and manage these other yield-limiting factors in the field, this will help us improve the overall resilience of crops to the vagaries of Mother Nature,” Nielsen said.
