The Weathering Properties of Silicate Rock Dust Under Laboratory Conditions
The ion exchange of the primary minerals is one of the central topics from the perspective of geological and soil scientific studies as well as papers concerning plant nutrition. The latter has been given great importance in the last years and decades as can be seen from the numerous publications addressing this theme. Today primary broadspectrum minerals hardly play a role as a carrier of nutrients in conventional agriculture
Information for the Application of Silicate Rock Dust for the Amelioration of Forest Soils
This report contains information for “fertilization with rock dust” with an orientation towards practical application. The widely used term “gesteinsmehl” will be limited here to pulverized rocks of silicate origin.
Pot Test Trial II of Basalt, Serpentine, Bentonite, Feldspar, and Kaolin
This is a report on the second set of pot test trials run by Dr. Gernot Graefe at the Gartnerhof in Ganserndorf Sud near Vienna.
Compensational Fertilization with Silicate Rock Dust For Buffering Damaged Forest Soils: First Experential Report
The fertilization of forest areas has increased substantially in recent years. In all, since 1982 over 500,000 hectares of forest were fertilized which is more than 7% of the forest area (in Germany). On about 95% of the areas fertilized in 1988, magnesium-containing lime (various types such as dolomite, limestone, etc.) was applied. On about 15% of the area, additional fertilization with several minerals, containing potassium and phosphorus were applied, in addition to the limestone.
Remineralization Trials: Minplus and Bananas A Cost Benefit Study
Banana Growers Kevin and Gary Harding have been trialing rock dust from Pin Gin Hill quarry since mid-1985. Using experience gained from these trials they radically altered their fertilizer applications, and in August 1990 planted out a 4 Hectare block using Minplus rock dust as the main fertilizer.
Effect of Silicate Rock Dust in Forests: Result of the Experiments in the Forest of Arenberg-Schleiden after Five Years
The advantage of rock dust is that it is a natural, raw material, and carrier of numerous minerals and trace elements with long term effect. The nutrients are released slowly and gently during the process of natural weathering in the forest ecosystem (without fertilization shock). In the following, we report the latest results of the experiments in the forest of Arenberg-Schleiden.
A Technique Called N-Viro Soil Remineralization Using Sewage Sludge Mixed with Cement Kiln Dust
Roughly 140 billion pounds of sewage sludge are produced annually in the U.S. in an attempt to separate our human wastes from the waters we mix them with. This number has steadily increased over the last two decades as more stringent waste water treatment regulations have been put into effect. Standard methods for dealing with sludge have included incineration, ocean dumping, landfilling, land application on farms and composting.
An Interview with Dr. Robert Bruck, Ph.D. Director of the Environment for North Carolina on the State of the Appalachian Forests and Remineralization
In North America we’ve seen over the past ten or fifteen years significant and serious decline of certain forest species. The ones we’re most concerned about are high elevation red spruce and Fraser fir forests in the Appalachians. These forests comprise very unique mountaintop ecosystems on four, five and six thousand foot peaks. They’re quite rate in that they’re remnants from the last glaciation period: very beautiful, very unique. We’ve seen very rapid decline, dieback and death of these forests occur to a great extent in high elevations of the eastern Appalachians.
Preliminary Results for the Soil Remineralization Forestry Trials On Grandfather Mountain in North Carolina
This is a brief summary of our preliminary experimental data regarding the effects of Planters II on the growth and survival of red spruce and Fraser fir. As a brief introduction, I would state that red spruce and Fraser fir are the boreal montane ecosystem species here in the high Appalachians of the northeastern and southeastern U.S. These tree have undergone tremendous stress via air pollution over the past several decades and, indeed, certain air-borne and satellite surveys have indicated that as much as 40 percent of this ecosystem has already died.
