Excerpt from Potash in the Greensands of New Jersey The work on which this report is based was begun in the fall of 1918 as a part of the systematic search for potash conducted by the United States Geological Survey since 1910. The New Jersey greensand marls have long been known to contain small amounts of potash, lime, and phosphate. For more than 100 years they were dug and marketed as fertilizer, and in the late sixties the annual amount so used aggregated nearly tons.1 With the introduction of prepared fertilizers the marl industry died away, but small amounts Of greensand are still dug and used here and there. It has been considered impracticable to extract commercially the potash from greensand because of the relatively insoluble char acter of the mineral in which the potash is locked up. Of late years, however, there has been considerable experimentation in processes Of extracting potash from silicate minerals, and the New Jersey greensands, which are silicates, have attracted attention because Of their accessibility, abundance, and relative ease Of mining. The scarcity Of potash resulting from the shutting out Of German supplies during the World War gave immtus to these experiments and permitted hope of the establishment Of a potash industry in the United. States in which the New Jersey greensands might be an important factor. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books. Find more at ...
