Abstract:
1. A method for preparing an extracted mineral element composition consisting of: one acid treatment step, a settling step, a separating step, and a concentrating step, wherein the one acid treatment step consists of admixing a clay soil, a mixture of clay soils, or a mixture of clay soils and leonardite with water in an amount at least two times the weight of the soil and an acid to produce a water-acid-soil slurry, wherein the amount of acid is 0.25% to 7.5% of the weight of the water; wherein the settling step consists of allowing solids from the water-acid-soil slurry to settle; wherein the separating step consists of separating the liquid of the water-acid-soil slurry from the settled solids wherein the solids comprise substantially all of the silica and aluminum from the clay soil, mixture of clay soils, or a mixture of clay soils and leonardite, and wherein the concentrating step consists of concentrating the separated liquid to form a liquid extracted mineral element composition comprising (i) calcium, chlorine, magnesium, manganese, phosphorous, potassium, silicon, and sodium, and (ii) a lower amount of silica and aluminum than the clay soil, a mixture of clay soils, or a mixture of clay soils and leonardite.
