I’ve combined five sources in this blog post about the amazing properties of rock dust for soil remineralization. Anyone with a garden or planning a garden needs to know about rock dust. Specialty brands with the widest range of minerals such as Azomite can be ordered online and through garden shops. You can also get rock dust very inexpensively from gravel quarries. It’s the powdered residue left over from crushing and processing gravel. As explained in the video above, 8 lbs./sq.yard of rock dust lasts 10 years!
Bread from Stones by Dr. Julius Hensel
“During the course of his researches, Dr. Hensel found that in the primeval rocks, as granite, lie a potentially inexhaustible supply of all minerals required for the feeding and regeneration of the soil, plants, animals and man. All that is required is to reduce them to finely pulverized form, so that their mineral elements may be made available to plants. Hensel wrote a book describing his discovery of a new method of creating more perfect fruits and vegetables, rich in all nutritional elements and immune to disease and insect pests, with the result that it produced worm-free fruit without the need of spraying. The foods so produced by rock-meal (rock dust) fertilization were true Organic Super Foods, far superior in flavor and value than those produced under the forcing action of manure or chemical fertilizers.
The use of various pulverized rocks, [such] as granite, limestone, rock phosphate, etc., in place of chemical fertilizers, will lead, claimed Hensel, to permanent restoration of even poor soils to the balanced mineral content of the best virgin soils; and the rock dust thus applied will remain year after year and not be washed away by rains or irrigation water, as is the case with highly soluble chemical fertilizers.
This will be an economic saving to the grower and enable him to sell foods at a lower price than when he must spend large sums on chemical fertilizers. Also, since foods thus mineralized are healthy and immune to plant diseases and insect pests (as Hensel experimentally demonstrated), there is no need for the expense and dangers of spraying.
Foods raised by Hensel’s followers, including many German gardeners and farmers, who were enthusiastic in praise of his method, were found to possess firmer tissue and better shipping and keeping qualities than those raised with animal manure or chemicals. And most important among the advantages of Hensel’s agricultural discovery is that foods grown on mineralized soil are higher both in mineral and vitamin content and so produce better health and greater immunity to disease than those grown by the use of chemical fertilizer sprays.”

Remineralize the Earth – Project in Costa Rica
“Remineralize the Earth, in partnership with John Todd of Ocean Arks International, embarked on a visionary mission in the hilly country of Guanacaste, Costa Rica. The Agroforestry Project in Costa Rica: Food, Fuel, and Income to Sustain Local Communities was a model project designed to demonstrate the potential and evaluate the effectiveness of remineralization while restoring the devastated tropical forests of the region.”
