Organic Colloids
Introduction to Soil Science / Poorly Crystalline Silicate, Oxide, and Organic Colloids
"Organic colloids are particles smaller than one micrometer that form through extensive decomposition of plant material and microbial remains. They are concentrated in O and A horizons and are especially abundant in Histosols. Their many pH-dependent charge sites give them high cation exchange capacity and strong abilities to retain nutrients and filter contaminants."
