DE36 is an approved feed additive (up to 2%) that is a natural blend of diatomaceous earth & montmorillonite. Our DE is granular which means less dust, less waste!

Millions of years ago, in all the waters of the earth, billions of microscopic one-celled plants, called diatoms, took the minerals from the waters & created a protective shell for themselves. The fossilized skeletal remains of these diatoms accumulated in layers on lake & sea floors forming deposits of what we know today as diatomaceous earth. Alias names include: diatomite, silicon dioxide, Kieselgur (Europe), Fuller’s earth, fossil shell flour, or simply DE.

DE deposits have been mined for centuries; used in hundreds of industrial & agricultural applications. There are two primary types of diatomaceous earth deposits - saltwater & freshwater. DE’s are also divided into grades: commercial, feed-grade & food grade like in your toothpaste.

Importantly, diatomaceous earths vary greatly in something called “free crystalline silica” (FCS). Common DE’s contain 8-25% FCS while pool-filter grade has a whopping 55%. Therefore, it is vital that only feed-grade DE one low in FCS be offered, place near or around animals & humans.

Saltwater DE is commercially processed primarily as a filter aid. Beer, wine, fruit juices, & vegetable oils are filtered through the diatoms' multitude of pores, acting as microscopic sieves. Swimming pool & fish tank filters utilize this commercial type material. Saltwater DE has a high crystalline silica content from a process called calcining (being exposed to high degrees of heat), it is not appropriate, in fact very dangerous to use in ingestible applications such as grain storage & or as an animal feed additive.

Freshwater DE (DE36) is mined from ancient lakebeds & ideal for agricultural uses with its less than 1% FCS. Documented use of diatomite by the Chinese for pest control dates back almost 4,000 years. Due to its ability to kill insects, DE has been used in grain storage for centuries. As awareness & concern about chemical pesticides grow, non-toxic, natural, diatomaceous earth is enjoying renewed attention & interest. Numerous farmers, ranchers & Amish tout DE as a natural anthelmentic (de-wormer), finding great success adding DE to their livestock feed to keep their goats, sheep, cattle, horses, pigs, & fowl healthy & parasite clean without the use of chemical drugs.
