  • Why is Pam used in soil recycling?
  • Since PAM is extensively employed in the recycling processes of excavated soil from solid wastes of construction, the surplus soil in sediments contains an unknown amount of PAM. These surplus soils can possess a greater water absorption and retention ability, benefiting crop growth ( Kebede et al., 2025; Wang et al., 2025b ).
  • Is polyacrylamide a good soil conditioner?
  • However, as these solutions are proposed, numerous doubts and opposing opinions are emerging. Polyacrylamide (PAM), also known as “soil conditioner”, “soil amendment” and “soil stabilizer” in soil science ( Gilda Dell'Ambrogio and Wong, 2019 ), is commonly used to modify the unfavorable and damaged characteristics of soil.
  • What are Pam formulations for irrigated agriculture?
  • PAM formulations for irrigated agriculture are water-soluble (linear, not gel-forming, not cross-linked, not super water absorbent) anionic polymers. They have typical molecular weights of 12-15 Mg mol -1 (over 150,000 monomer units per molecule).
  • Does Pam affect soil chemistry?
  • Sorptive dynamics of the common pesticides, 2,4-D and atrazine, were not dramatically altered by PAM treatment of field soil samples, but some slight changes in desorption and degradation rates were reported (Watwood and Kay-Shoemake, 2000).
