APFIVE Cation Exchange Capacity and Soil Properties
How does the concept of cation exchange capacity in soil relate to its ability to maintain stable nutrient levels and pH?
A
Lower CEC increases soil’s ability to resist changes in nutrient levels and pH
B
Higher CEC allows soil to retain more cations, buffering against nutrient loss and pH changes
C
CEC has no impact on nutrient retention, only affecting soil structure
D
CEC primarily influences soil color, indirectly affecting nutrient availability
