Jersey Greensand, so-called from its only known place of origin, New Jersey, was deposited millions of years ago when the Garden State was still under water. It is mined primarily for water purification purposes but increasingly more and more people in agriculture and horticulture are requesting it for the soil.

Benefits from Greensand are for the most part unexplainable. If you brought some into an ag science lab and asked for an analysis, they would most likely tell you the product is worthless. However, numerous greenhouse trials show that there is a lot more to it than what you would read on a lab report. Organic growers have, for years, extolled the virtues of Greensand without really knowing how or why it has improved their crops.

One possible explanation is mineralization. Studies have shown that mineralizing soil can improve the taste, color, nutritional value and health of various plants as well as the overall health of the soil. Mineralization also improves soil life by increasing populations of certain bacteria that can slowly dissolve insoluble mineral nutrients. Those bacteria eventually cycle themselves into organic matter that further increases populations of many other varieties of beneficial microorganisms.
