Harvest, row crop, 20pct standing stubble O 04 op_notes4 ARS record - filename is: Harvest Wheat - grain (combine cutterbar header).oprn This operation record is designed to represent actual field harvesting operation of removing the grain from small grain crops with a cutterbar 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. Added 0.2 for the flatting of the combine and tire trafic for haulling grain. MAS 1-18-07 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". oenergyarea 14.311503 ostir .15 G 02 gbioarea 1.0 P 31 kilflag 2 P 43 cutvalf 0.65 cyldrmf 1 cplrmf 0 cstrmf 0 harv_report_flg 1 harv_calib_flg 1 harv_unit_flg 0 mature_warn_flg 1 P 34 frselpool 0 ratemultvt1 1.0 ratemultvt2 1.0 ratemultvt3 1.0 ratemultvt4 1.0 ratemultvt5 1.0 threshmultvt1 1.0 threshmultvt2 1.0 threshmultvt3 1.0 threshmultvt4 1.0 threshmultvt5 1.0 P 40 P 24 fbioflagvt 0 massflatvt1 0.15 massflatvt2 0.15 massflatvt3 0.15 massflatvt4 0.2 massflatvt5 1
