Harvest schedule to fill storage for year-round delivery of grasses to biorefinery

► Four scenarios estimated the days available for harvesting switchgrass over 9-months, July through March. ► Beginning harvest in July and extending through March required 33 balers compared to 64 balers for a short (October-December) season. ► Maximum required storage capacity was 75% of the total annual harvest for the short season and 44% for the extended season. ► Capital cost to build storage was reduced by 41% by selecting the extended harvest season.
