  • 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.
  • What is the stabilizing efficiency of polyacrylamide?
  • The stabilizing efficiency of polyacrylamide is mainly determined by the adsorption of its macromolecules on the surface of soil particles . The aggregate formation contributes to several beneficial phenomena such as stability increase, reinforcement of soil structure, water infiltration promotion as well as erosion limitation .
  • 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].
  • How does polyacrylamide stabilize soil?
  • The addition of polymer to the soil stabilizes existing aggregates and strengthens the mutual binding of adjacent particles. The stabilizing efficiency of polyacrylamide is mainly determined by the adsorption of its macromolecules on the surface of soil particles .
