Natural soil additive according to the fertiliser ordinance.
100% diabase rock of volcanic origin from the Vogtland (Saxony).
Provides your soil with many minerals, micronutrients and silica.
Diabas-primary rock powder is for everyone who wants to cultivate their soil sustainably - from amateur gardeners to organic farmers. It is used as a natural soil additive (§ 2DüG) in horticulture and agriculture.
The powder's essential properties for use in agriculture are its very high buffering capacities and its effects of providing a long-lasting stabilisation of the soil pH values. These will counteract the acidification processes of your soil. The mineral components of primary rock supply your soil with minerals and trace elements that are important for plant growth.
The formation of soil to humus is promoted and increased while the supply of nutrients to your plants is optimised. This is also favored by a high silica content (SiO2 approx. 40%). The use of Diabas-primary rock powder also improves the physical consistencies of the soil and its water retention. This activates soil life and increases soil fertility. The plants become more resistant to diseases and fungi while their growth is nurtured. If added during the composting process, decomposition is accelerated and insect population is reduced. The primary rock powder also reduces unpleasant odors if stirred into herbal manure.
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!
