MINING AND MARKETING ALTERED VOLCANIC TUFF AT THE HEART OF NATURE'S ALUM/SULFUR MINE

摘要

An alum/sulfur deposit (USDA organic registered) was mined underground for alunite (K,Na) Al_3 (SO_4)_2 (OH)_6 from the early 1900s to the 1930s. It is now being mined as an open pit quarry. A larger assemblage of minerals is included with this method (Alunite, Potassium-Alum, Jarosite, Gypsum, Native Sulfur and K-feldspar). This assemblage of minerals provides the necessary requirements as a Volcanic Soil Conditioner Sulfur-Potash. Heart of Nature™ Company has been marketing this product to farmers on the west coast as a (1) pH reducer, (2) soluble sulfur and potassium source for plant growth and (3) soluble calcium. Recently, a new market has been tapped. This product has been found to solve many odor, bacteria and algae problems faced in the dairy industry.
