Abstract

The decomposition and transformation of above‐ and below‐ground plant detritus (litter) is the main process by which soil organic matter ( SOM ) is formed. Yet, research on litter decay and SOM formation has been largely uncoupled, failing to provide an effective nexus between these two fundamental processes for carbon (C) and nitrogen (N) cycling and storage. We present the current understanding of the importance of microbial substrate use efficiency and C and N allocation in controlling the proportion of plant‐derived C and N that is incorporated into SOM , and of soil matrix interactions in controlling SOM stabilization. We synthesize this understanding into the Microbial Efficiency‐Matrix Stabilization ( MEMS ) framework. This framework leads to the hypothesis that labile plant constituents are the dominant source of microbial products, relative to input rates, because they are utilized more efficiently by microbes. These microbial products of decomposition would thus become the main precursors of stable SOM by promoting aggregation and through strong chemical bonding to the mineral soil matrix.

  • The POM fraction is predominantly plant-derived C and its increase is driven by the increment in quantity and quality of plant C inputs to the soil and management practices such as tillage cessation.

    “The POM fraction is predominantly plant-derived C and its increase is driven by the increment in quantity and quality of plant C inputs to the soil (Gulde et al., 2008;Cotrufo et al., 2013) and management practices (i.e., tillage cessation) (Six et al., 2000).”

    From Carbon sequestration potential in perennial bioenergy crops: the importance of organic matter inputs and its physical protection (2016) · cites this paper as Cotrufo et al., 2013

    The MEMS framework section says plant-input quality and quantity affect litter decomposition and soil organic matter formation. It does not establish that the POM fraction is predominantly plant-derived or that increases in those inputs specifically increase POM. The citing sentence attributes tillage cessation to Six et al., not Cotrufo et al. (LLM, conf=0.84)

  • Enhanced belowground microbial activity may result in greater stabilization of organic matter.

    “which may result in greater stabilization of organic matter [25].”
  • A large fraction of added C-particularly for biochar-can be retained in the soil over several decades or longer, although residence times vary depending on amendment type, nutrient content and soil conditions.

    “Thus a large fraction of added C -particularly for biochar -can be retained in the soil over several decades or longer, although residence times vary depending on the amendment type, nutrient content and soil conditions 35”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
