Group: Biomass Manipulation (G 02)

The "Biomass Manipulation" group contains a shared parameter that is required by many WEPS processes that simulate the manipulation of biomass (e.g., the removal of biomass, flattening of standing residue, etc.). This "group" line is commonly used for operations that do not affect (till) the soil, where the shared parameters dealing with tillage depth in the "Tillage" group are not required. Examples of operations that would use this "group" line are harvesting and spraying operations. It's parameter is:

Area Affected
Surface area afffected (bounded between 0 and 1). A 0 would represent no surface area affected. A value of 1 would mean that the tillage processes occured across the entire width of the implement. A value between 0 and 1 would indicate that a fraciton of the surface and soil beneath would be disturbed.
