Several variables are used
to describe residue.
|
|
Size and toughness, replaces
the fragile, non-fragile concept.
|
|
5 types defined.
|
|
Decomposition is a function
of distribution of stems, leaves, pods, roots, etc. but a single value is
used.
|
|
Also a single value is used
for above ground and below ground decomposition.
|
|
Mass-cover
relationship. Enter a data point on
curve. RUSLE2 self-calibrates.
|
|
Stay with core values in
core databases. Interaction of
mass-cover, residue at harvest and decomposition. Change of one requires recalibration of
RUSLE2.
|
|
RUSLE2 captures main
effects.
