Abstract

Water soluble polyacrylamides (PAM) have been used in laboratory studies to maintain the structure and permeability of soils subjected to artificial rainfall (Levy et al.. 1991: Shainberg et al., 1990). In a field study. Mitchell (1986) increased furrow infiltration into a clayey soil by 30-57% during the first 4 hr of an irrigation by applying 150 g m-3 (150 ppm) PAM to the irrigation water during inflow. An initial small application of anionic polyacrylamide to irrigation water nearly eliminated furrow sediment loss on Portneuf silt loam (Lent: et al..1992; Sojka and Lent:1993 ). Application of 10 g m-3 (10 ppm) PAM (per unit of water) during furrow advance reduced total sediment loss from treated furrows by 94% and increased net infiltration 15% (Lent: and Sojka, 1994a).
