South Texas Gardener; Importance of rock powder

Rock dust, also known as rock powders, rockminerals, rock flour, soil remineralization, and mineral fines, consists of finely crushed rock, processed by natural or mechanical means, containing minerals and trace elements widely used in organic farming practices.

(Corpus Christi) — Rock dust for your garden. And why you want to use it.

What is rock dust?

Rock dust, also known as rock powders, rockminerals, rock flour, soil remineralization, and mineral fines, consists of finely crushed rock, processed by natural or mechanical means, containing minerals and trace elements widely used in organic farming practices. This gardening ingredient is the other half of the "healthy plants come from healthy soil" equation.

In healthy living soil we want a diverse array of bacteria and microbiology to help with every phase of plant growth because of how they convert minerals like nitrogen phosphorus and potassium into usable plant food. Rock dust such as Azomite contain a large scope of minerals that serve as micronutrients to the plant. A growing site devoid of the micronutrients that we tend to undermine will have a lot tougher time growing to its optimal health.

Think of it like this. If all we are conserved with it growing a large plant fast, then one mite be dependent on chemical fertilizers and grow a large plant realitivly quicker like putting on size by eating candy bars and cake. Yes one would grow large completing the goal but would one be healthy? Growing a healthy plant is very much the same. For a strong and healthy plant to grow and have strong defenses and a abundance of nutrition then those things that elements such as boron (B), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), zinc (Zn), nickel (Ni) and chloride (Cl) must be present in the soil. Azomite Rock Dust is an excellent source of readily available calcium, iron, magnesium and potassium plus trace elements and micronutrients. It also increases phosphorous availability to plants. Glacial Rock Dust improves soil structure, moisture holding properties, nutrient availability and bacterial action. Azomite and Glacial Rock Powder has more divers mineral content than Rock phosphate. Rock phosphate is a rock dust but is typically acidified with sulfuric acid to make it more readily available to a plant as seen in liquid fertilizers but does not have the biologically conducive properties to encourage micro organism diversity and growth along with lack of mineral diversity.
