Diatomaceous earth (diatomite) is popular for use in gardens to control insects in a chemical free way. It has a growing use in agriculture. For a long time it has been used as an addition to ammonium nitrate fertilizers to prevent caking and ensure even spreading. It is important as a carrier for other agricultural products, particularly fertilizers. It can be added to stock food or rubbed into the animal fur. This may have benefits to the overall health of the animals. Diatomaceous earth fines can be applied liberally around plants for the control of slugs, snails and other chewing animals.
