Calcined Clay Bonsai Soil Amendment

Calcined clay is primarily used for growing bonsai. Calcined clay are stable soil amendments that improve soil quality through increased cation exchange capacity, increased microbi@l activity, nutrient retention, and water holding capacity all of which increase plant yield.
