Abstract

On three soils, 3-amino-2,5-dichlorobenzoic acid (amiben) at 1.5 and 15 ppmw did not inhibit the nitrifying microflora, but 150 and 1500 ppmw significantly reduced the nitrate nitrogen produced by the soil microflora. No breakdown of amiben in liquid media was detected during 70 days. Amiben had a net minus charge in solution, and traveled at about the same rate on paper strips in electrophoresis as the dye brilliant blue. The organic matter content of soil was the property most closely associated with adsorption of 14C-labeled amiben. Only kaolinite, of four clays studied, adsorbed amiben significantly. There was no volatilization of amiben from stainless steel planchets stored at temperatures of 15, 25 or 35 C and relative humidities of 0, 33, 66, or 100 per cent.
