Mineral-associated organic carbon in tropical soils: is it persistent, is it desirable, and can the literature answer? A systematic review protocol
Year: 2026
Type: preprint
Abstract: Protocol for a systematic review of mineral-associated organic carbon in tropical and subtropical soils. This is the second version. It replaces an earlier protocol after a pilot scoping survey of 31 records showed that three of the intended methodological moderators — sonication energy, mass recovery of the fractionation, and sampling season — were reported in none of them, which makes the originally planned meta-regression impossible and becomes a finding in its own right. The survey table is deposited alongside the protocol so that every count cited in it can be checked.
