Harvest Tool (combine cutterbar header - fixed height cut) O 04 oenergyarea -1 ostir -1 op_notes4 ARS template (tool) record - filename is: Harvest Tool (combine cutterbar header - fixed height cut).oprn This operation record is designed to represent actual field harvesting operations such as removing the grain yield of small grain crops like soybeans with a cutter bar 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. Note that the harvested component can be changed from the "reproductive material" to other plant parts, so it can be used for non-grain type harvesting operations as well. Any crops harvested with this operation will default to killing the crop unless the appropriate "kill" process parameter is changed. 200x Created - Fred Fox Oct 31, 2005 Updated notes - Larry Wagner Detailed info regarding this operation record: This harvest record specifies the actual cut height independent upon the height of the crop. If the crop is too short for the specified cut height, the operation may not harvest all of the intended material (yield). If one wants a variable cut height, based upon the height of the crop at harvest time, they should use the "Harvest Template (fraction crop height cut and remove)" operation. 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.
