Short summary
Crop residues are widely available on-farm resources containing carbon and nutrients, but, as soil amendments, their decomposition does not always benefit the soil. We applied mixtures of crop residues that are chemically different from each other and found significantly increased soil organic matter and available nitrogen levels. Applying crop residue mixtures has practical implications involving the removal, mixing and reapplication rather than simply returning crop residues to soils in situ.
