This paper focuses on evaluating the tradeoff of reduced storage cost to increased cost associated with loss of material and decreased material quality. Production scale stacks of bales were monitored to evaluate commercial scale degradation within field edge storage for various methods of coverage. Dynamic trends of degradation were monitored using a thermistor temperature logging system and real time vertical temperature profiles were generated to evaluate the spread of microbial activity within the bale stacks. Weather data and moisture sampling results indicate that temperature shifts within the bale stacks coincided with rainfall events and increased moisture content. Deconstruction of the stacks generated final moisture profiles and permitted assessments of dry matter loss after one year of storage. The trends and profiles developed from these findings were used to assess the impact of degradation on the feedstock contribution of ethanol production cost (FCEPC).(Download PDF) (Export to EndNotes)
