CEC

Here are some general ranges of CEC (in cmolc/kg soil) for various soil orders

  • Luvisols: 10-30 cmolc/kg soil
  • Podzols: 10-20 cmolc/kg soil
  • Solonetz: 15-30 cmolc/kg soil
  • Chernozem: 20-40 cmolc/kg soil
  • Vertisol: 35-50 cmolc/kg soil
  • Organic soils: 130-150 cmolc/kg soil

There values are dependent on pH of soil, since portion of their CEC is due to organic matter, which changes with soil pH
