Zeolite in the garden, to improve the soil

Today we are talking about zeolite, a mineral that can have very interesting applications in the garden, structurally improving the soil and making fertilization and irrigation more efficient. It is an entirely natural product, very little known but which can give excellent satisfaction.

The name “zeolite” comes from the Greek and means “boiling stone”, these are stones that release water when heated, hence the origin of the name. Zeolites are minerals of volcanic origin, resulting from the encounter between incandescent lava and sea water, which have a microporous structure (i.e. an internal structure made up of numerous cavities, connected by channels ). 52 different mineralogical species are grouped together under the name of zeolites, we do not go too much into the art of physical and geological characteristics, but we will tell you how useful it can be for those who cultivate.

The effects of zeolite

The microporous structure allows the zeolite to absorb and filter liquid or gaseous molecules. In the cold, this mineral absorbs more, while it is released in the heat. In addition, the crystal structure of the mineral has a catalytic behavior, that is, it promotes chemical reactions. These extraordinary properties offer interesting applications in agriculture: if mixed with the soil, they can, in fact, produce several positive effects.


  • Adding zeolite to sandy soil increases water retention, the mineral absorbs water and releases it as the heat increases. This is particularly useful in times of drought: the zeolite reduces the need for crop irrigation.

  • Added to clay soil, zeolite improves its permeability, prevents water stagnation and promotes greater soil aeration.

  • If added to acidic soil, it corrects excesses by changing the pH.

  • The presence of zeolite in the soil retains nutrients, preventing them from being washed away by rain, thus optimizing fertilization.

  • It gradually releases the potassium, phosphorus, sodium and calcium contained in the mineral, thus having a long-lasting effect of enriching the soil and nourishing the crops.

  • Reduces soil temperature range, preventing thermal shock to plants.

On the grower’s side, there will also be less need for irrigation and fertilization, which will save money and less labor.


The zeolite will be added to the garden soil, beating it on the surface, in the first 10/15 cm of soil. The amount of minerals to add obviously depends on the characteristics of the soil, but to obtain appreciable results you need a good amount (10/15 kg per square meter). For more information about zeolites and their use, we recommend that you contact specialists. We got help from the company Geosism&Nature . If you are curious about zeolite, you can ask them directly for advice, contact Dr. Simone Barani ( info@geosism.it Is 348 8219198 ).

It should be noted that, unlike fertilizers, zeolite is permanent, it is a mineral that remains in the soil and not a substance that is consumed by crops. The cost of buying the zeolite and the work of incorporating it into the ground will pay for itself over time thanks to the benefits we have discussed in this article.
