Dust from and erosion of earth surfaces is controlled by the application of a fatty acid containing material such as used vegetable oil, animal renderings, or a combination thereof such as Yellow Grease to the surface and allowing the surface to harden and dry. The hardening and drying of the surface may be accelerated by making an at least semi-emulsion of the fatty acid containing material with a surface binding material such as lignin, magnesium chloride, calcium chloride, or a mixture thereof, and water. With the at least semi-emulsion, the fatty acid containing material makes up between about 30% to about 75% of the product, the surface binding material makes up between about 10% and about 40%, with the water making up the remainder. The product is applied to the earth surface to be treated and dries in several hours. The fatty acid containing material or semi-emulsion product appears to be absorbed by the top layer of earth forming the surface and binds the earth particle together to form a relatively hard and water repellant surface which resists the generation of dust and reduces erosion and wear of the surface.
