Scope and method of study. The purpose of this study was to estimate the number of suitable field workdays per month in which switchgrass can be harvested in Oklahoma at different probability levels. This study also sought to determine the effect of the number of workdays on the cost to deliver a flow of feedstock to a biorefinery. A soil moisture balance model, drying model of cut grasses, and empirical CDF were used to determine the number of field workdays for mowing and baling operations at different probability levels. A mixed integer mathematical programming model was used to determine the optimal biorefinery location, the quantity of biomass feedstock, monthly harvest and storage quantities, optimal number of mowing and raking-baling-stacking harvest machines, and the cost to deliver feedstock to a biorefinery.Evapotranspiration and Irrigation Water Requirements:ASCE Manuals and Reports on Engineering Practice No.70. ... of Agricultural Engineers Paper No. 74 -1019.
