Abstract
This article analyzes economic tradeoffs among harvest date, fertilizer applied, nutrient removal,
and switchgrass yield as they vary with respect to input and output prices. Economic
sensitivity analyses suggest that higher biomass prices lead to earlier harvest. Optimal harvest
time occurs beyond time of maximum yield because nutrient removal in the biomass is an
important economic consideration. Switchgrass price premia that reflect the cost of nonoptimal
harvest time are driven by standing crop yield loss, nutrient removal, storage loss,
and opportunity cost. These price premia could provide a mechanism to compensate producers
for alternative harvest times and aid with logistics management.
