Diatomaceous Earth also known as DE is a naturally occurring, soft, siliceous sedimentary rock that is easily crumbled into a fine white powder. It is used as a soil conditioner, because like perlite, vermiculite, and expanded clay, it retains water and nutrients, while draining fast and freely, allowing high oxygen circulation within the growing medium.
Diatomaceous earth can have a significant beneficial impact on the physical, chemical and biological processes of soil, water and the growth of crops.
DE provides the plant with energy and reinforced its ability to protect itself against stress. Soil treated with DE will have optimum fertility through improved water, physical and chemical properties and by allowing nutrients in the soil, such as phosphorus, to remain in a plant available form.
Diatomaceous earth is used in agriculture for grain storage as an anticaking agent, as well as an insecticide.
