Which soil has the highest cation exchange capacity?

✅ Explanation:
-Cation Exchange Capacity (CEC) is the ability of soil to hold and exchange positively charged ions (cations) like calcium, magnesium, and potassium, which are essential plant nutrients.
-Clay loam has the highest CEC among the given options due to its higher clay content. Clay particles have a large surface area and a negative charge, allowing them to attract and hold more cations.
