In this article readers are introduced to the many facets of soils - their unique characteristics and diversity, the ecosystem services that soils provide, and their use and misuse.
Clay minerals are composed essentially ofsilica, alumina or magnesia orboth, and water, but iron substitutes for aluminum and magnesium in varying degrees, and appreciable quantities of potassium, sodium, and calcium are frequently present as well. ...
them. Some users report that clay powder poultices are more effective for poison ivy than commercial preparations. In Africa, tribes in some areas use clay poultices to treat wounds and ulcers that are resistant to healing, with clays that scientists are studying for their antibacterial properties....
