  "id": "MLC-T-ENV-000373",
  "term": "Active Fraction Organic Matter",
  "field": "Environment",
  "definition": "The highly dynamic or labile portion of soil organic matter that is readily available to soil organisms. May also include the living biomass. Particulate organic matter (POM) and light fraction (LF) are measurable indicators of the active fraction. POM particles are larger than other SOM and can be separated from soil by sieving. LF particles are lighter than other SOM and can be separated from soil by centrifugation.",
