Notes

Upper Boundary Consideration: There is no evidence of a detrimental ecological threshold; benefits plateau at 100% cover. However, an agronomic upper limit exists due to practical constraints. Very high residue loads (>95%) can lead to short-term N immobilisation, physical impediments for machinery, and potential pest risks if not managed properly.
