Polyacrylamide (PAM) was found to improve soil structure (Saybold 1994) by reducing clay dispersion. An anionic PAM having large molecular weight has the ability to stabilize soil structure, reduce runoff, and soil loss (Zhang and Miller 1996) when soil solution cations can bridge negatively charged clay particles with anionic PAM (Theng
