RUSLE2 computes residue at
maximum canopy as a linear function of yield.
The result is that the typical residue to yield ratio increases as
yield decreases.
|
|
Key point: It is the
residue at maximum canopy that is described.
Not residue at harvest. RUSLE2
computes residue at harvest.
|
|
Two data points are entered
to describe relationship.
|
|
One check is to consider the
residue at zero yield.
|
|
Vegetation like corn can
have residue at zero yield.
|
|
Vegetation like grass would
not have a residue at zero yield.
