Naturally occurring in marine sedimentary deposits, Down To Earth’s Greensand is composed primarily of the blue-green siliceous mineral glauconite. Traditionally used to loosen heavy clay soil or to hold together loose sandy soils, DTE Greensand is able to absorb up to one-third its weight in water to improve the moisture holding capacity of garden soils and potting mixes. DTE Greensand is highly recommended for vegetables, fruits, herbs, lawns, ornamentals and all types of trees and shrubs.
