\nNaturally 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 of 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.
