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.
Western Australia is semi-arid, with annual rainfall on the same order as Africa’s Sahel. Our soils are ancient many millions of years old. Ages of weathering and leaching, and a few decades of farming with soluble NPK fertilizers, have left them impoverished. Today, despite the greatest care, each year large tracts of land are lost to salt and wind erosion. Shelterbelts of trees are indispensable allies in an effort to reverse this loss of farmland, and to anchor a regeneration of the soil. Significant forest cover can eventually stabilize the local climate, too. The Western Australia chapter of Men of the Trees is dedicated to this task.
The field of mineral sequestration for the long-term storage of carbon dioxide is a CCS (carbon dioxide capture and storage) option that provides an alternative for the more widely advocated method of geological storage in underground cavities, especially at locations where such underground cavities are not available, where the risk of leakage of the CO2 stored underground is considered unacceptable, or where large resources of material suitable for carbonation are present. Although the state of the art of mineral carbonation processing technically suffers from too slow chemical kinetics and poor energy economy, the driving forces for continued ...
