Book Description
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.' With the introduction of prepared fertilizers the marl industry died away, but small amounts of greensand are still dug and used here and there.
