Lava flour improves the structure and health of your soil

Lava flour is finely ground volcanic rock. It is rich in silicon in well-absorbable form for plants. Silicon increases the resistance of the crop and to drought, diseases and pests. In addition to Silicon, it contains 83 other minerals that together improve the fertility and health of your soil.

Together with organic matter from, for example, compost or worm droppings, lava flour ensures a good granular soil structure. As a result, clay soil becomes rougher and allows the water to pass through better. Sandy soil can retain nutrients and water better and peat soil is stabilized against degradation.

To be used for

  • Weed control (helps well against moss and horsesaus, read more in this blog)
  • Pest control (snails, lice, spreading over wet leaves)
  • Natural fertilization (wet spraying after sprinkling or covering with worm manure)
  • Diseases (spraying against fungal disease on boxwood)
  • Soil structure improvement (mixing with worm manure)
  • Control of fruit flies in your worm box (see this article)
  • Improve the health of your compost worms and the quality of your worm compost.
