An agricultural spray may be produced by admixing citric acid and glutamic acid with a metal salt and a pesticide or other agricultural chemical containing components capable of precipitating with the metal salt in the admixture. The citric acid and the glutamic acid chelate with the metal salt to provide a stability and compatibility-enhancing composition, thereby preventing the metal salt from forming an insoluble solid within the admixture. Such a composition may be produced by admixing citric acid and glutamic acid at a molar ratio of about 6.8:0.5 to about 1:0.29. The composition may include a metal sat, citric acid and glutamic acid in a molar ratio of about 1:6.8:0.5 to about 1:1:0.29 and a pesticide.
