Co-utilization of rock dust, mineral fines and compost

This report examines the relevance and potential of techniques using rockdust to remineralize soils in Scotland. Rockdust (RD) is a generic term applied to fine materials produced as by-products of quarrying and mineral processing. The concept is concerned with making available a multitude of minerals from freshly crushed rocks that are considered by advocates not to be present in larger quantities in weathered soils. Claimed benefits include : •enhanced long term sustainable soil fertility and diverse soil biology; •multi-season effects; •enhanced plant establishment, growth and vigour; •compatibility with organic farming practices; ...

Food Patterns Equivalents Intakes by Americans: What We Eat in America,

The 2015-2020 Dietary Guidelines for Americans (DGA) encourage Americans to increase their fruit, vegetables, and whole grains intakes and limit added sugars and solid fats intakes [1]. This report highlights the salient changes in the U.S. population’s intake of selected USDA Food Patterns groups, including added sugars and solid fats, using What We Eat in America, NHANES 2003-2004 and 2015-2016 dietary data [2-4].

Carbon Dioxide Mineralization Feasibility in the United States

Geologic carbon dioxide (CO2) storage is one of many methods for stabilizing the increasing concentration of CO2 in the Earth’s atmosphere. The injection of CO2 in deep subsurface sedimentary reservoirs is the most commonly discussed method; however, the potential for CO2 leakage can create long-term stability concerns. This report discusses the feasibility of an alternative form of geologic CO2 storage: CO2 mineralization. In this method, CO2 reacts with rocks and minerals to form solid and stable carbonate rocks. New pilot projects and laboratory-based kinetics experiments have revealed that this method, both in situ and ex situ, may be a viable ...

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.
