What to Expect with Variable Rate Paying Back

July 22, 2011
By: Margy Eckelkamp, Farm Journal Machinery Editor and Test Plot Director

Variable-rate technology may not reduce inputs as much as put them in the zone to provide you with the biggest payback. However, variable-rate technology is a high-management practice, and Brad Beutke relays the following lessons he shared at the 2011 Corn College in central Illinois.

“There are many things that a farmer needs to ask themselves before they step into variable-rate,” Beutke says. “They need to make sure they set the foundation using the Systems Approach, which includes pest management, uniform stands, getting your tillage right, and a comprehensive fertility plan.”
 
He explains that the farmers getting the biggest pay back from variable rate population and variable rate nitrogen application have the Systems Approach integrated across their acres.
 
“However, with variable rate the paybacks can be significant,” he says. “With variable rate population we are able to lower population in less productive areas while still maintaining yields.”
 
A lesson he has learned in the field has been where populations are raised, nitrogen also needs to be increased.
 
“Farmers may think they’ll be using less nitrogen with variable rate, but we are trying to shift where we are putting that fertilizer on the fields,” he says.
 
As for where to start, Beutke says it is often easier for farmers who are already in the process of purchasing a new planter to outfit it for variable rate. And more retailers are supplying farmers with toolbars that are variable-rate ready.
 
However, he says if he had to pick between variable rate planting or variable rate nitrogen, he’d go with nitrogen.
 
“But remember that you need to have a firm handle on a comprehensive fertility program with soil testing and nitrogen timing,” Beutke says.
