Importance of Soil Colloids in Soil Chemistry
- Nutrient Exchange: Soil colloids have a high surface area and are crucial for the cation exchange process (where nutrients like calcium, magnesium, potassium, etc., are exchanged between the soil and plants).
- Water Retention: Colloids can hold significant amounts of water due to their surface charge, helping in maintaining soil moisture levels.
- Soil Fertility: They play a key role in fertilizer efficiency and contribute to soil fertility by providing a medium for nutrient retention and release.
