The ability of certain soil particles to transfer mineral ions between their surfaces and the soil solution is referred to as
A) soil acidity.
B) soil alkalinity.
C) colloidal action.
D) cation-exchange capacity.

Question

Quizplus · Accepted Answer

The transfer of mineral ions between soil particles and the soil solution is primarily facilitated by negatively charged particles on the surface of soil particles, known as colloids. This process is referred to as cation exchange, and the ability of soil particles to participate in it is called their cation-exchange capacity. Therefore, the correct choice is D.
