  • What is an anionic polyacrylamide (PAM)?
  • The use of soil amendments, including anionic polyacrylamide (PAM), is one of many options for protecting soil resources. In most applications, anionic polyacrylamide (PAM) is often used as a soil amendment to manage infiltration, runoff and soil erosion ( Entry and Sojka, 2003, Lentz et al., 1998, Lentz et al., 2001, Sojka et al., 1998 ).
  • Can polyacrylamide be used as a soil conditioner?
  • The favorable effects of the environmentally friendly, nontoxic, anionic polyacrylamide (PAM) as a soil conditioner have long been established. Some uncertainties exist, however, regarding the effects of PAM molecular weight (MW) on its performance as a soil amendment and its ability to penetrate into aggregates and stabilize interior surfaces.
  • Does polyacrylamide reduce soil erosion in furrow irrigation?
  • Research results indicated that PAM application decreased soil erosion in furrow irrigation significantly (Trout et al., 1995 ). Polyacrylamide treatments showed the greatest infiltration improvement and erosion reduction compared with the controls.
  • Do anionic polymers affect smectitic soil stability?
  • We studied the effects of two anionic polymers, a high-MW (12 × 10 6 Da) and a medium-MW (2 × 10 5 Da) PAM, using deionized water (electrical conductivity of 0.004 dS m −1) or a 15 mmol L −1 gypsum solution, on the stability of aggregates from four smectitic soils varying in clay content.
