Particularly suitable for improving the binding and nutrient availability of lighter, more permeable soils.

  • Soil conditioner, especially for light sandy soils.
  • Natural calcium bentonite that stores water and nutrients.
  • When added to sandy soil, this light clay swells up, almost jelly-like and stops the soil from drying out. Unlike heavy clays, bentonite doesn't form lumps, so plants roots have no trouble obtaining moisture from their surroundings.
  • Excellent for adding to soils in container plants.
  • Improves the water balance of light soils and protects the plants from dehydration.
  • Promotes soil fertility by forming stable clay-humus complexes.
  • High content of easily convertible silica and minerals.
  • A light sprinkling several times a year over the soil, supplements and revitalizes the garden.
  • High nutrient storage capacity, improves the efficiency of fertilizers.


  • Light soils 150g - 300g m², medium soils 100g - 150gm², heavy soils 100g - 50 g  m², approx. 5 cm deep.
  • Sprinkled in layers on compost it helps breakdown material into humus.
