Ideas in this flowchart

  • Ion exchange in soil
  • Ion exchange is rapid and reversible.
  • Ions in solution swap with oppositely charged sites on soil surfaces.
  • Cation exchange
  • Cations in solution exchange with cations held on negatively charged surfaces.
  • Anion exchange
  • Anions exchange at positively charged surfaces.
  • Common exchangeable ions
  • Cations: H⁺, Al³⁺, Na⁺, K⁺, Ca²⁺, Mg²⁺, and NH₄⁺.
  • Anions: NO₃⁻, SO₄²⁻, and Cl⁻.

"Ion exchange is the rapid and reversible swapping of ions in solution with oppositely charged sites on soil surfaces. Cation exchange involves cations in solution exchanging with cations held on negatively charged surfaces, while anion exchange involves anions and positively charged surfaces. Common exchangeable ions include H+, Al3+, Na+, K+, Ca2+, Mg2+, NH4+, NO3−, SO42−, and Cl−."
