Chelated compositions and methods of making and using the same

Abstract

A composition includes a first chelating agent, a second chelating agent, and a plurality of metal ions. In one embodiment, the second chelating agent includes citric acid and is different than the first chelating agent. A method for forming a composition includes mixing a first chelating agent, a second chelating agent, and a metal salt together to form a mixture and processing the mixture to form at least one of a granulated composition and a powdered composition. In some embodiments, the second chelating agent includes citric acid and is different than the first chelating agent.

What is claimed is: 
     
         1 . A method of providing nutrients to a plant, comprising:
 applying a composition to at least one of a portion of the plant and foliage proximate the plant, the composition including a first chelating agent, a second chelating agent different than the first chelating agent,   wherein the first chelating agent includes at least one selected from the group consisting of ethylenediamine tetraacetic acid and tetrasodium ethylenediamine tetraacetate and the second chelating agent includes citric acid, and wherein the composition is in the form of at least one of the group consisting of a plurality of granules and a water-soluble powder.   
     
     
         2 . The composition of  claim 1 , wherein the composition is in the form of a plurality of granules. 
     
     
         3 . The composition of  claim 1 , wherein the composition is in the form of a plurality of granules, one of the plurality of granules includes at least one molecule of the first chelating agent, at least one molecule of the second chelating agent, and at least one of the plurality of metal ions. 
     
     
         4 . The composition of  claim 1 , wherein the composition is in the form of a water-soluble powder. 
     
     
         5 . The composition of  claim 1 , wherein the composition is a water-soluble powder, the powder having a plurality of particles, one of the plurality of particles includes at least one molecule of the first chelating agent, at least one molecule of the second chelating agent, and at least one of the plurality of metal ions. 
     
     
         6 . The method of  claim 1 , wherein the composition is in the form of a water-soluble powder, the method further comprising dissolving the composition in an aqueous solution prior to the applying.
