Mineral soil additive in compliance with the fertilizer ordinance.
100% diabas rock of volcanic origin from the Vogtland region.
Provides your soil with a wide range of minerals, micronutrients and silica.

From hobby gardeners to organic farmers – Diabas-Primary Rock Powder supports sustainable soil management through the addition of valuable minerals. It is used in horticulture and agriculture as a soil additive (§ 2 DüG).
Essential for agricultural use are the long-lasting stabilization of the soil pH-value and the very high buffering capacity of the rock powder. These counteract an acidification of the soil. The chemical constituents supply the soil with minerals and micronutrients that are important for plant growth. Humus formation is promoted and the nutrient supply for plants is optimized. This is also supported by the high silica content (SiO2 about 40%). The use of Diabas-Primary Rock Powder also improves the physical properties of the soil and its water retention capacity. Thus, soil life is activated and soil fertility is increased. Plants become more resistant to diseases and fungi, and growth is promoted. When added during composting, the rotting process is accelerated and insect infestation is reduced. If the primary rock powder is stirred into plant manure, it reduces unpleasant odors.

Diabas-primary rock powder has a wide range of application:

  • Your lawns are supplied with an optimum of trace nutrients.
  • The structure of your soil will be improved.
  • Your soil will be supplied with valuable minerals and trace elements.
  • Your plants will become stronger and more resilient.
  • Your harvest will show a higher yield.
  • Fruit trees are strengthened and become more resistant in the long run.
  • Your compost is optimally enriched while insects and unpleasant odors are diminished.
  • Dissolved in water or herbal manure, Diabas-primary rock powder is poured directly onto your plants.
  • Dispersion of Diabas-primary rock powder into an organic waste bin reduces fermentation gases and prevents infestation of decomposing elements with maggots.
     

You can sprinkle and intermingle Diabas-primary rock powder on or in your soil or use it in dissolved form in water and herbal manure.
Diabas-primary rock powder can be used during all seasons!
An overdose of the soil does not occur!
