Each year there are a few acres replanted somewhere due to adverse environmental conditions. The replant decision must be made by weighing the production of a replanted crop versus the production of the damaged field if left untouched.
It’s easy to let emotions influence a replant decision, but it’s important to make the decision based on facts, logic, and economics. To aid in this decision Wyffels has developed this replant calculator that will help take emotion out and let the facts drive the decision.
