Abstract: The invention disclosed is a method of making a chelating agent and a method of forming a chelated compound using that chelating agent. The chelating agent is formed in two steps. In the first step, methanol with a small amount of citric acid and concentrated nitric acid is used to remove whatever compounds in leonardite ore that is soluable in methanol. The resulting mixture is then mixed with sodium citrate and dried causing the methanol to evaporate. The result is a chelating agent. It is ground into a fine powder and can be mixed with finely ground powders of the sulfates of the desired micronutrients such as for example ferrous sulfate. The two powders when so mixed combined to form a chelate. The resulting dry material is then reground into a powder and can contain up to 22% of the chelated micronutrient.
