It is a component with intraparticle pores and very light that floats in water. These micropores are capable of trapping and retaining water that is strongly retained by adhesion forces, making water, therefore, hardly available to most plants. However, cacti and succulents with their “double” suction power can more easily use this water that is retained with a matric potential between 50 and 100 cm of water column. It has the capacity to act as a nutrient pantry.

In summary, the pumice:

  • It represents a small reserve of NUTRIENTS, due to its modest cationic exchange capacity.
  • It is friendly to the rhizosphere. Favors the structure of the soil/substrate.
