HM 9754 is a mixture of various weighted humic molecules, often called humic acids. Past published research has shown the role humic acids can play in stabilizing nitrogen not from affecting biological transformations, but instead by chemical chelation or cation/anion exchange mechanisms. All ore sources have different compositions and therefore perform these task at different efficiencies, hence a necessity to evaluate each ore source. Presented are 35 site years of studies conducted throughout the Midwestern United States evaluating the yield impact on maize. Results show that in the presence of nitrogen loss mechanisms, volatilization and leaching, yields increased significantly when nitrogen was applied, either pre-plant, or side-dress, with HM9754 in conjunction. In the absence of loss mechanisms improvements still occurred but on a lower scale.
