  "id": "MLC-T-MET-004201",
  "term": "Cation exchange capacity",
  "field": "Meteorology and atmospheric science",
  "definition": "A measure of the total capacity of a soil or other material to hold exchangeable cations, expressed in milliequivalents per 100 grams or centimoles of charge per kilogram. This property reflects the amount of negative charge sites on soil particles that can attract and retain positively charged ions. Clay minerals and organic matter contribute significantly to a soil's cation exchange capacity.",
