Product description:The SUBSTRAL Naturen primary rock flour is a ground material that is obtained from rocks of volcanic origin. Primary rock flour is a mineral soil additive that enriches the garden soil with trace elements, improves soil fertility and increases the water-holding capacity. Primary rock flour contains different amounts of iron compounds, minerals such as potassium, calcium or magnesium as well as trace elements. Microorganisms, water and soil acids decompose the finely grained rock and make the micronutrients it contains available to plants. It is ideal for high-yielding crops such as tomatoes, cucumbers, pumpkins and potatoes and helps with the regeneration and restoration of lawns. On the compost, primeval rock flour binds unpleasant odours.
