Basalt Dust

What is basalt dust?

Basalt dust is a 100% natural product. Basalt rock, used in dust production is rich in macro- and microelements as well as oxides, which are necessary for plant gro. It contains ingredients that are not being provided by artificial mineral fertilizers created in chemical plants. Basalt dust contains many minerals and microelements in compositions and proportions most common in nature. That’s why it’s a simple, convenient, and natural way to supply the necessary minerals for soil, and thus to the plants. Basalt dust is a safe fertilizer, not allowing for mineral overdose or supplying it in incorrect proportions.

How is basalt dust created?

Basalt dust is obtained by grinding a volcanic rock to a granularity of 100µm . Currently available dusts are acquired as waste from crushing the raw basalt for commercial purposes like chippings, rubble, or hydraulic stone.

The dust made this way is open-graded and the grain size can get up to 2 mm. It’s a reused waste product, with parameters depending on many variables in the production process of the main part of the mineral aggregates, as well as the pollutants getting into the final product.

Our goal is to start a production line for basalt dust that will be the only product without waste. It will be created in a fully controlled process with a stable chemical composition and physical parameters. We do have our own basalt deposit with an optimal chemical composition, from which the raw material will be used in basalt dust production.

Acquired raw material with parameters verified by the factory production control will then go to a processing plant – a specialized mill capable of grinding hard rock to a dust with granularity of barely 100 µm.

The processing plant is a modern and environmentally friendly investment powered by electricity with negligible impact on the environment.

Example application


  • used during plowing and tilling in spring and autumn
  • used as main ingredient as well as supplement in organic fertilizers (e.g. compost, manure, slurry, bird droppings)
  • Basalt dust can be used to speed up snow melting, and with melted water will be automatically used as fertilizer.


  • Strengthens plants
  • Increases immunity to sickness
  • Corrects soil structure
  • Regulates soil pH
  • increases the biological value of crops, enriching plants with essential minerals, which are a source of macro and microelements for humans and animals
  • Remineralizes soil
  • Helps with fruit and vegetable taste
  • Protects plants from pests if used in the powder form
  • Thanks to high silicon content strengthens plant cell walls, increasing their resistance to lodging, freezing, and pests
  • It can be used for seed treatment, increasing their resistance to fungal diseases
  • Works very well in combating aphids and cabbage flies if used as a plant spray while also protecting plants from fungal diseases that attack vegetable, tree, and shrub leaves
  • If used to encircle the plot, it can assist in combating snails as well
  • Can be used as mineral additive to manure and slurry


  • High quality concrete production
