If a silage crop or hay crop is being harvested (the grain/fruit/seed/root/tuber box is NOT selected), then the % dry matter removal should contain the total amount of residue removed from the field.
If a crop is being harvested for its grain, fruit, seed, root or tuber (the grain/fruit/seed/root/tuber box IS selected), the dry matter removal should include any other residue removed aside from the G/F/S/R/T.
Ex: Corn harvest where only ears are removed, enter 0%; Silage event may have 85-95% dry matter removed; mid-season alfalfa harvest may have 50% dry matter removal
