  • Does polyacrylamide dissolved in water reduce soil erosion?
  • We can conclude that the polyacrylamide dissolved in water with 45% concentration leads to highest protection of soil and results in the lowest soil erosion under rain day. Also, the soil loss decreases with the increase of the protection layer through the spray of a growing quantity of polymer solution (from 0.5 to 0.75 L).
  • How does polyacrylamide protect soil?
  • Within this perspective, polyacrylamide (PAM) is one of the polymers that used to protect the soil by covering it with a layer of water-soluble polymer. This polymer controls the soil erosion by collecting the soil particles and preventing them from drifting under critical weather conditions such as heavy rain and torrents.
  • Is polyacrylamide a water soluble polymer?
  • Polyacrylamide (PAM) is a water-soluble polymer used to bind soil particles together for gaining stability against water and wind erosion. It is highly water-absorbent. This chapter aims to study the PAM properties like thermal degradation and melting point by Differential Scanning Calorimetry (DSC).
  • Does polymer solution spray reduce soil erosion?
  • Soil loss of samples treated with different concentration of PAM under run spray We notice from Fig. 3 that the soil erosion of samples without treatment by polymer solution spray attains the highest value (about 0.254), while the treated sample (45% con.) has the lowest value of soil loss (about 0.097).
