Clay minerals together with micro-organisms, organic material, even grains of sand, form an indispensable soil substance, namely the “clay-humus complex”. The clay-humus complex provides, among other things, pH buffering, regulation of phosphate and sulphate, the exchange of nutrients for the plants, and even moisture, air, and heat management in the soil. Clay minerals have a pH7-8, contains 6-8% moisture, and can absorb up to 135% water.
