Abstract: A system and method for amending existing soil to conserve water and fertilizer utilizes the application of a slurry comprised of phytosanitary certified organics and water. The method includes mechanically mixing a variety of organic materials into slurry which may be applied to a prepared section of land using a conventional pump, hose and nozzle or other types of commercially available spraying equipment. The composition of the slurry is specifically formulated for supplying nutrients and water while improving the water and fertilizer holding capabilities of the existing soil by homogenizing with the soil. The slurry comprises entirely organic ingredients which are selectively and custom blended with various nutrients, organic pesticides and/or organic herbicides to accommodate specific needs of agricultural products, horticultural species, grasses or other plant life being grown in the soil.
