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).
