Foundation for Variable Rate Application

July 27, 2011 10:53 PM

When farmers are looking to step into variable the first consideration is collecting all of the necessary data.

“The most important thing is that they are going to need four to six years of reliable data to come up with zone maps,” says Brad Beutke who presented on the topic at the 2011 Corn College. “This includes well-calibrated yield maps, soil test maps, soil line maps, and remote sensing technology.”
Those data layers can then be stacked on top of each other to refine managements zones in the field.
“We work in management zones based on soil types and then make adjustments based on the other data,” Beutke says. “We can refine zones to 3 to 7 acres.”
Once the lines are drawn on the map, farmers should conduct on-farm plots to verify how their fields will respond to variable-rate application and determine population and nitrogen rates.
“The biggest hurdle to adopting variable rate is collecting the data and establishing the management zones,” Beutke says. “With the new equipment and technologies making variable rate work in the field is easier than ever.”
