effect of polyacrylamide integrated with other soil

experimental plots were established on cropland measuring 4 m by 1.3 m at a slope gradient of 8% (fig. 2).runoff collector trenches with trapezoidal cross sections (2.5 m long and 1 m wide on the top, 1.5 m long and 0.5 m wide on the bottom, and 0.6 m deep) were dug below each plot and lined with a geo-membrane plastic sheet to prevent water loss by infiltration (fig. 2).

acute and long-term effects of anionic polyacrylamide (apam,polyacrylamide (pam) are high molecular weight polymers deriving from the polymerization of acrylamide monomers. their chemical composition and ionic character depend on the functional groups added to the acrylamide chemical moiety (abidin et al., 2012; acharya et al., 2010). they can occur in non-ionic form, or as polyelectrolytes in cationic
