Tierra de Diatomeas y Tierra de Sommières: Usos y Diferencias

Diatomaceous Earth and Sommières Earth: Uses and Differences

The world of technical minerals is vast and diverse, offering innovative solutions for various industrial and domestic applications. Two of the most prominent in this area are diatomaceous earth and Sommières earth. Although both share absorbent properties, they have key differences in their origin, composition and uses. In this article, we will explore these differences and how they can benefit you.

Diatomaceous earth:

  • Origin and Composition: This soil is derived from fossil remains of diatoms, single-celled microalgae with silica cell walls.

  • Main Uses:

    • Agriculture: A powerful ally against insects and parasites, damaging their exoskeleton and leading them to dehydration and death.
    • Filtration: Essential in water filtration systems, such as swimming pools.
    • Absorbent: Perfect for spills and humidity control.
    • Animal feeding: Works as a supplement and anti-caking agent.

Land of Sommières:

  • Origin and Composition: A natural clay coming mainly from Sommières, in France. Its main component is montmorillonite.

  • Main Uses:

    • Stain remover: It is its star application, capable of removing grease stains on fabrics and stones.
    • Absorbent: Similar to diatomaceous earth, it absorbs spills efficiently.


While diatomaceous earth is noted for its versatility, from crop protection to water purification, Sommières earth is more specialized, being especially valued for its ability to treat difficult stains.


Both technical minerals offer practical solutions to everyday challenges. Whether you're looking to protect your garden, purify your pool, or save that favorite shirt from an oil stain, the answer could be found in one of these amazing products.
