Studies conducted at Tennessee Valley authority, National Fertilizer and Environmental Research Center, Muscle Shoals, Alabama, have been shown that salts of phosphorous acid have solubilities significantly higher than those of corresponding phosphates.

W T B Technology has studied TVA's research and has developed a phosphite fertilizer line that will give maximum solubility and mobility of the phosphorous acid and potassium that is present in the NutramixTM P, PK, and NPK line of phosphite fertilizers.

Our reaction process and quality control produces a highly refined, pure and stable product.
