The higher the cation exchange capacity of a soil,the greater is its buffer capacity.

Question

Quizplus · Accepted Answer

Cation exchange capacity (CEC) is the soil's ability to hold positively charged ions (cations) and exchange them with the soil solution. A soil with high CEC can hold more cations, including hydrogen ions (H+) that affect soil acidity, which leads to a greater buffer capacity. Buffer capacity refers to the ability of the soil to resist changes in pH when acid or alkaline substances are added. Therefore, the statement is true.

The Higher the Cation Exchange Capacity of a Soil,the Greater
