Biostimulant composition. The invention relates to a biostimulant composition for plants, comprising (i) micronized zeolite and (ii) micronized calcareous algae, such as, for example, lithothamne. The mass ratio between the zeolite content and the calcareous algae content is between 0.1 and 10, preferably between 0.25 and 4. The particle size of the zeolite, respectively of the calcareous algae, is such that the diameter D90 is less than 20 μm and preferably less than 10 μm, or even less than 4 μm, when it is measured by laser granulometry in accordance with standard ISO 13320:2020 on the basis of the Fraunhofer diffraction model. The zeolite and the calcareous algae together represent at least 60% by mass, preferably at least 75% by mass, and even more preferably at least 90% by mass, of the solid matter of the composition. |
