Trelease and Trelease (2) have called attention to the advantages, from the standpoint of pH control, of using mixtures of ammonium and nitrate salts in making up nutrient solutions. Sulphuric acid is customarily employed as a means of adjusting the pH of solutions during an experiment. The purpose of this paper is to call attention to the advantages of using nitric acid as a means of maintaining at one and the same time both H-ion concentrations and nitrate levels. The writer has used nitric acid for this purpose over a number of years with considerable success.
