The cost to take a forage stand out of production will change depending on which termination strategies are employed. However, what is cost effective for one producer may not be for another. Table 1 outlines the expenses associated with terminating a stand. The cost of any given termination strategy will change with the cost of fuel, equipment and herbicides. Producers must consider geography, environmental conditions, stand composition, efficiency of termination and re-cropping options when determining the economics of forage stand termination.
