Clay is a fundamental driver of many soil properties and in many ways defines what a soil is capable of growing and storing. The clay fraction in soils are any mineral particles less than 2 microns in size. As a result, the combined clay fraction has a significant surface area and therefore a large capacity for nutrient and carbon storage. The clay fraction also provides physical protection for soil microbes against predation.
