Harvest Grain Sorghum - grain (combine row header) O 04 oenergyarea -1 ostir -1 op_notes4 ARS record - filename is: Harvest Grain Sorghum - grain (combine row header).oprn This operation record is designed to represent actual field harvesting operation of removing the grain from small grain crops with a row head on a combine. This harvesting operation record removes all the reproductive component of a crop above the cutting height. Typically this is specified as the "yield" component in the crop record. The non-harvested crop plant material above the specified cut height becomes flat residue. The remaining above ground crop material below the specified cut height becomes standing residue. Nov 02, 2005 Created - Larry Wagner Detailed info regarding this operation record: This harvest record specifies the actual cut height dependent upon the height of the crop. The cut height is specified as a fraction of the crop height. Some standing crop stalks could be flattened during the harvesting process, e.g. by the harvester's tire tracks. Therefore, a flattening process is also a part of this operation record. The default values are set to zero, assuming no flattening of standing stalks are occuring. However, these can be set as necessary for the specific harvesting device used in the operation. The harvesting operation could also have an effect on the "standing stalk" fall rate and fall threshold values. The default "biomass pool" flag parameter is set to "No adjustments applied" so that no "stalk residue decay rate change" will occur. However, this flag value can be changed along with the default parameter values to change the "stalk residue decay processes". op_devnotes4 Enter dev notes here.
