  • What is anionic polyacrylamide?
  • Anionic polyacrylamide is polymer with a large number of negatively charged moieties in the long chains of the PAM macromolecules. It can be obtained by partial hydrolysis of polyacrylamide neutral amide groups, which is shown in (3). This process occurs under moderate temperature by adding sodium hydroxide to the PAM solution [4, 6].
  • Does anionic polyacrylamide treatment improve seedling emergence and growth?
  • Wallace A (1987) Anionic polyacrylamide treatment of soil improves seedling emergence and growth. HortScience 22:951 Wallace A, Wallace GA (1986) Effects of soil conditioners on emergence and growth of tomato, cotton, and lettuce seedlings.
  • Does polyacrylamide reduce soil erosion?
  • Soils treated with polyacrylamide maintain their original physical state in water erosion conditions. By stabilization of clay mineral aggregates by polymer adsorption, the water infiltration rate improvement and soil erosion reduction are observed.
  • Is polyacrylamide a good soil conditioner?
