Khumic E+, composed of humic acids and potassium, significantly enhance CEC through multiple mechanisms

Cation Exchange Capacity (CEC) is a critical parameter reflecting a soil’s ability to retain and exchange positively charged nutrient ions (e.g., Ca²⁺, Mg²⁺, K⁺, NH₄⁺), essential for plant growth. A higher CEC enhances soil fertility by reducing nutrient leaching, stabilizing pH, and improving microbial activity. For instance, soils rich in clay minerals like montmorillonite (CEC: 100–150 cmol/kg) or organic matter (CEC: 100–300 cmol/kg) exhibit superior nutrient retention compared to sandy soils with low CEC. CEC also mitigates heavy metal toxicity by binding harmful cations (e.g., Cd²⁺, Pb²⁺), thereby protecting groundwater and soil health.

Impact of Khumic E+ Potassium Humate Granules​​

Khumic E+, composed of humic acids and potassium, significantly enhance CEC through multiple mechanisms:

Organic Matter Enrichment: They increase soil organic carbon, which provides additional negatively charged exchange sites for cations, boosting CEC by up to 20% in degraded soils.

Soil Structure Improvement: By promoting soil aggregation, they enhance porosity, water infiltration, and root access to nutrients.

Nutrient Synergy: The potassium in humate granules binds to exchange sites, improving K⁺ availability for plants while reducing leaching.

pH Buffering: Humic acids stabilize soil pH, optimizing conditions for cation exchange and microbial activity.
