There are so many uses and applications for diatomaceous earth (DE) all around the world today. One of the main uses for DE is a filter media for wine, beer, juice, oil, and swimming pools. Another main use for diatomaceous earth is as a functional additive for paint & coatings. Then there's DE as an insecticide, animal feed, soil amendment, absorbent, seed coating and in fertilizer. The applications for DE are endless. In this post from Quantum Agriculture, Australia, Alan Johnstone covers what DE is and key uses for soil and animal care. The Aussie vernacular makes this post even more interesting.
Diatomaceous Earth consists of the fossilized remains of millions of microscopic single cell plants called diatoms which were deposited millions of years ago on the beds of oceans and lakes. Its uses in agriculture are many. It is a useful addition to compost heaps and the soil because it is a once living form of silica and has high paramagnetism. It stimulates healthy growth of plant root systems. It conditions the soil by making silica available to plants, improving cation exchange capacity, soil conductivity, and helps the soil to retain water. It is advised that a calcium source (hydrated lime, agricultural lime or gypsum) be added at the same time so that the calcium and cations can occupy the sites left by aluminum which is bounded by the soluble silica.
