Harvest Template (cut, windrow and bale) O 04 oenergyarea -1 ostir -1 op_notes4 ARS template record - filename is: Harvest Template (cut, windrow and bale).oprn This operation record is designed to represent the combined harvesting operations, e.g., "mowing", "windrowing" and "baling", where all of the above ground crop biomass is removed above the specified cutting height. Examples would be cutting alfalfa for hay bales. This harvesting operation record removes all crop plant material above the specified cut height. The remaining above ground crop material below the specified cut height becomes standing residue for annual crops. Perennial crops like alfalfa will automatically regrow. The default "Kill or Defoliate Growing Crop" parameter is set to kill annual crops but to allow regrowth of perennial crops. Thus the default value is acceptable for perennial crops like alfalfa and most annual crops like corn harvested for silage. There are situations where one might want to change this parameter value for specific types of crops and conditions. See additional info below in the "Detailed info regarding this operation record" section. No standing stalks (crop or residue) are flattened. This record is assuming an operation like a row crop silage harvester, where the tires are tracking in between the rows or the flattening is considered negligible, e.g., flattening the remaining stalks of growing alfalfa plants. Nov 01, 2005 Created - Larry Wagner Detailed info regarding this operation record: This operation template has the "Kill or Defoliate Growing Crop" process parameter defaulting to "Annual crop killed, perennial crop regrows" value. Thus the default value is acceptable for use with perennial crops like alfalfa and annual crops like corn harvested for silage. However, if one intends to harvest (green chop) an annual crop that has the capacity to regrow after such a cutting, then one needs to change the value to "No crop killed" to allow the crop to regrow afterwards. Due to the way WEPS reports crop yields, the crop record selected for this type of harvesting operation should specify the "yield" component of the crop to be the "above ground stems, leaves and reproductive elements of the plant". This will ensure proper reporting of harvested yields by WEPS. However, using a crop record that does not specify the "yield" component in this manner will not affect the erosion estimate or change any other simulation run results, except to incorrectly report the true "yield" component being removed from the field. An example of a crop that may be harvested for two different types of "yield" components is alfalfa. There are alfalfa crop records defined that specify the yield as the reproductive element (seed) and others that are defined for harvesting the crop as hay. op_devnotes4 Enter dev notes here.
