Comment:
Harvested LTER Cellulsic Biofuels Experiment (CE Study), Treatments C4-C12 (all replications). Harvested the biomass crops i.e. switchgrass, C3 and C4 mix and prairie grasses mixes. Harvested with JD 7330 tractor using the 7.5 ft wide Kemper head and Wintersteiger biomass harvester weighing system. The middle 7.5 ft was harvested out of the middle of each plot. Plot weight was obtained from the on-board Mirus computer weighing system, by Juniper Systems. Cutting height of plant stubble was approximately 6 inches. Grab samples from each rep were placed in paper bags weighed for wet weight and placed in plant dryer and will be reweighed to determine percent moisture for each treatment and replication. Started harvest in south west corner (C11:plot 101) and harvested in straight lines headed North, working towards the East. Kemper head chute came out of Wintersteiger receptacle in plot 203 CE4. Kemper head lower chute jammed with biomass in plot 109 CE12, this resulted in the loss of most of the harvest sample. To compensate half of the head's width (approx. 3.75') was harvested on either side of the original pass.
