ROCK DUSTS REMINERALIZE THE EARTH
Improves soil fertility and plant health.
Good for you and the planet.

What Are Rock Dusts?

Rock dust is also called rock flour, rock powder, stone meal, stone flour, rock mineral, mineral fertilizer, and mineral fines. Rocks are finely crushed either mechancially or by nature such as by glaciers. They contain natural trace elements and minerals. Organic farmers and gardeners love them.

Each type of rock powder supplies different percentages of nutrients. The major minerals found in these dusts are potassium (K), phosphorus (P), calcium (C), and magnesium (Mg). They also contain trace elements such as zinc (Zn), silicon (Si), copper (Cu) and iron (Fe). Nitrogen (N) is not found in them.
 
High in Trace Minerals that Your Soil Needs

Igneous rocks such as granite, basalt, hornfels and rhyolite have high mineral content. Rock powders do not usually contain high levels of potassium, nitrogen or phosphorus so they are used with fertilizers that do provide them.

Examples of rock dusts include Azomite, Rock Phosphate, Greensand, Basalt powder, glacial gravel, granite powder, and gravel dust (see below for more about them). They are slow release and natural.

 
How Soil Remineralization Helps You

Rock dusts are all natural, slow release, and good for the environment. Plants take up more nutrients thereby increasing yield, health, disease resistance, drought/frost tolerance, and productivity.

Remineralizing your soil creates higher Brix levels (sweetness) of fruits and vegetables.
 
Regenerate Your Soil and Whole Ecosystems

Earthworms love them. It helps build up soil humus and reduces soil erosion. Soil holds more moisuture. The soil needs fewer fertilizers to maintain productivity.

Fruit and nut trees love stone meals. Rock dusts can be added to dying forests to regenerate them. Trees are healthier, and the entire ecosystem is benefited.

"I had always wanted to learn more about the rock dust. I had learned about it from Dowser Extraordinaire, Phillip Callahan, who came to speak to our local dowsers chapter (Appalachian Chapter of the American Society of Dowsers) in the 90's." -Maria, Cliffside, North Carolina

 
You Need Microbes in Your Soil to Activate Rock Dust

Compost is alive with microbes. You can start by adding your rock powder to compost. Add 2 to 20 pounds per cubic yard of compost. Add some soil to your compost too. The dust speeds up the rate of decomposition. It reduces odors.

When adding it to your soil, it is important for there to be an adequate amount of organic material (it contains microbes).

The finer the powder, the easier it is for the microbes to use it. It should feel soft like bread flour. Scientifically, it should fit through a fine 200-mesh screen (sieve).
 
Glaciers and Volcanoes Remineralize the Earth

When the earth is in an Ice Age, glaciers move slowly across the earth and crush rocks into smaller and smaller pieces. This dust is blown into the air and distributes across the planet (loess). It also dissloves into water creaing glacial milk (cloudy water).

Volcanoes also add minerals to the earth when they erupt. These minerals come from deep within the earth, spreading over the planet as a fine dust.

Adding rock dusts to your soil is acting in accordance with the ways of nature. Plants love it. Rock dust is used by practitioners of Biodynamics.


 
Types of Rocks Used as Stone Meal

Granite dust has a lot of potassium (K in NPK fertilizer). It has calcium and magnesium. It is high in trace minerals such as silicon and iron, usually over 50 of them.

Azomite is hydrated sodium calcium aluminosilicate (HSCAS), naturally mined. It contains 70 trace minerals. A very valuable addition of a wide-spectrum of minerals.

Rock Phosphate is a great source of natural phosphorus, calcium and essential trace elements. It is over 30% phosphate, 48% calcium (calcium oxide). The rest is trace minerals (about 22%).
 
More About Rocks Used as Stone Meal

Greensand is a naturally occurring iron-potassium silicate (glauconite). It is a wonderful soil conditioner because it absorbs and holds moisture. It contains calcium, potassium, iron, magnesium, and phosphorus plus 30 other trace minerals.

Basalt contains potassium, phosphorus, calcium, magnesium and iron.

Glacial gravel (glacial rock powder) is from many different rocks that have been ground down slowly over millennia by glaciers.

Rocks Not High in Trace Minerals

Most sedimentary rocks (limestone and dolomite) are used to balance soil pH and provide calcium / magnesium. Limestone is mostly calcium carbonate and is good for most acid soils in moderation.

However, it should not be added to forests because in the long run it destroys the humus-building complex.

Limestone is low in most trace minerals and micronutrients.

The book The Enlivened Rock Powders by Harvey Lisle shows how to use rockdust as a fertilizer, compost activator, and plant growth stimulator. He explains the spiritual and cosmic aspects of rocks. Lisle is an expert in biodynamic techniques and dowsing.
 
"Bread from Stones" by Julius Hensel

Dr. Julius Hensel wrote his pioneering book Bread from Stones in 1894. He was a German Agricultural Chemist who discovered that adding finely ground rock dust (stone dust) to soil gave plants resistance to bacterial, fungal and insect attack.

He was opposed to the use of synthetic (non-organic) chemicals in agriculture. Fifty years later organic farmers and gardeners joined him in this thinking.

He also believed, based on farm tests, that stone meal could replace not only agriculture chemical fertilizers but animal supplements too.

Read the pdf Bread from Stones, a 111 page book: A New and Rational System of Land Fertilization and Physical Regeneration.
 
Sustainable Agriculture

Hensel recommended the non-caustic, gentle minerals of pulverized rocks, especially granite. He united agricultural chemistry with biochemistry and nutrition creating a theory that the chemistry of life is basically determined by the chemistry of the soil, and that synthetic fertilizers unbalance and destroy proper soil chemistry.

Powdered rocks restore normal soil mineral balance, producing food that is high in nutrition and flavor. His book is a classic of sustainable agriculture, a man way ahead of his time.
 
"The Survival of Civilization" by John D. Hamaker

Written in 1982 Mr. Hamaker discusses our environmental and climatic disarray and decline. His book covers large cycles of geological time, explaining how the quality and quanity of minerals in our soil greatly affects our health and the health of the planet.

Mr. Hamaker was a mechanical engineer and agronomist (expert in soil management and field crops) who studied soil science and paleoclimatology (climates of past ages). Based on geological cycles he determined that rock dusts (rock flours) were needed to bring back minerals currently missing in our soil.

This improves the nutrition of our food and thus our health. The same effect occurs when remineralizing forests or pastures. He believed it was economically viable and necessary to add rock minerals to poor soils on a massive scale.
 
"Secrets of the Soil" by Peter Tompkins and Christopher Bird

"The Survival of Civilization is regarded by a growing movement worldwide as a blueprint for the survival of the Earth, restoring ecological balance and, perhaps, even recreating Eden. The health and well-being of all living things ultimately depends on a highly mineralized, alive and vibrant soil. Rock dust adds up to a hundred elements and trace minerals and can greatly increase yield and quality of food, making organic agriculture truly viable. Undertaking the task of remineralization is urgent to restore our agricultural soils, to save the dying forests in the temperate latitudes, and to stabilize our climate."

-Peter Tompkins, co-author of The Secret Life of Plants and Secrets of the Soil.
