Soil Additives High in CEC

What are soil additives high in CEC?

CEC, or cation exchange capacity, is a measure of a material's ability to hold positively charged nutrients within the growing media. Soil additives with a high CEC are commonly included in potting mixes and living soil blends to complement the physical and chemical properties of the growing medium.

Our range includes natural mineral and carbon-based amendments suitable for a variety of gardening and horticultural applications.
