Give your Beds a Boost with Organic Greensand by Espoma. Espoma Greensand is the highest quality, all-natural, non-burning, purest Greensand obtainable. Espoma Greensand is mined from natural deposits of glauconite. These deposits are of marine origin and are composed primarily of iron–potassium silicate, which gives them a bluish-green color. Potassium is an essential nutrient needed by all plant life. Other valuable properties of Espoma Greensand are its ability to loosen clay soils, bind sandy soils, and increase the water-holding capacity of all soils. It is an exceptional soil conditioner for flower beds, gardens, and lawns.
