Greensand has been used as a soil amendment and conditioner since the early 1700s. Naturally occurring in marine sedimentary deposits, our Greensand is derived from the mineral Glauconite, a rich source of Potash and Iron. Greensand also has unique physical properties that are claimed to help loosen compacted clay soils and improve the moisture holding capacity of sandy loams.
