A water soluble metal amino acid chelate is prepared by adding a metal salt to deaerated water, mixing the salt solution with a mixture of an amino acid and an organic acid and adjusting the pH of the resulting composition to a range of from about 4.5 to about 8.5 to produce a clear solution. The resultant clear solution can then be applied to plants or it can be dried for storage. The water soluble metal amino acid chelate produced by the process, when applied to plants, results in increased metals assimilation and improved plant growth.
