Harvest operation, mechanical season final harvest, low soil disturbance, residue remains on soil surface,
example use: annual, cucumbers, pumpkin, melons, can be used for various bean vine crops, strawberries.
Annual crop killed, perennial regrows.

Represents harvest equipment like a tomato harvester that pulls the vine and runs the entire plant through,
separating the fruits from the residue and placing the residue back on the ground. Some slight soil disturbance . 121604DTL
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.

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".
