Description
The potential cation exchange capacity (KAKpot) represents the amount of cations interchangeably bound in the soil at a pH of 8.2 in cmol/kg. The illustration includes the KAKpot for the first meter.
very small (< 4 cmol/kg),
low (4 to < 8 cmol/kg),
mean (8 to < 12 cmol/kg),
high (12 to < 20 cmol/kg),
very high (20 to < 30 cmol/kg).
