"I prefer to use Bentonite Clay rather than kaolin clays because it has greater water retention capacity and a higher CEC (cation exchange capacity) resulting in higher fertiliser retention. Bentonite clay added with organic matter into sandy soils greatly reduces water repellency and increases nutrient holding."

"Adding Bentonite clay is a smart way to create a garden for a lifetime"
