Calculate the Benefits of Replanting

May 10, 2012 10:30 AM

Need help calculating a replant decision? A new mobile tool from Pioneer Hi-Bred can help you calculate replant numbers on the go.

Available to be accessed at mobile, the new tool takes into consideration the original planting date, original target stand count, plant population and the potential replant date. The tool will show you two profit scenarios, one for your current crop and your potential replant crop. Farmers must take seed and input cost considerations on their own.

"Although every grower tries to target the best planting date and stand, things happen that can negatively impact the crop early in the season," says Chuck Bremer, Pioneer agronomy e-business information manager. "The replant calculator helps growers address the tough question of whether to keep their current stand or replant to achieve a new stand that more closely meets their original yield target."

The calculator was built off a chart widely used throughout the Corn Belt that was developed by Emerson Nafziger of the University of Illinois several years ago. The current shift to higher plant populations suggested by Pioneer is also reflected in the tool.

Bremer says farmers have to be good managers to be able to take advantage of this tool.

"The new replant tool is just that—a tool. To a great extent, it relies on the grower having a realistic yield expectation and taking time to enter critical data, from optimum stand to grain price," he says.

Pioneer warns that replanting might not necessarily guarantee a farmer will achieve their desired yield mark if their replant decision is delayed enough. Similar to making the decision to replant, this new tool is not a straight arrow, but another item to add to your toolbox for decision making.

Pioneer’s Replant Calculator is an addition to their suite of mobile tools which include a Growing Degree Unit Calculator, PrecipEstimator, Growth Stage Estimator and Corn Yield Estimator. Learn more at
