Agricultural fertilizers with montmorillonite clays

Abstract

An agricultural or horticultural fertilizer, and method of making the fertilizer, featuring processed montmorillonite clay and other ingredients for improving plant growth and health. Liquid fertilizers for use in drip irrigation may comprise potash in an aqueous blend, as well as citric acid and humate. The method involves the preparation of a montmorillonite mineral-humate solution, which solution is mixed with other ingredients. In an early step, the montmorillonite and the humate are mixed with water and citric acid, and then blended or mixed over a period of time sufficient for the citric acid to leach the montmorillonite and humate into solution. The solution is then filtered to remove solid mineral residue. The filtered solution is then mixed with Aloe vera and potash to prepare a concentrated liquid.
