  • What is polyacrylamide (PAM) used for?
  • npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
  • Do polyacrylamides improve soil agrochemical transport?
  • Assigned to Associate Editor Sam Carrick. Polyacrylamides (PAMs), when applied as a soil amendment, purportedly improve soil infiltration, decrease erosion, and reduce offsite agrochemical transport.
  • What is high molecular weight polyacrylamide (PAM)?
  • Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
  • Does polyacrylamide increase grain yield?
  • Similarly, Lentz and Sojka (2009) reported that anionic EC PAM applied at 10 mg L −1 in furrow to a silt loam textured soil increased soybean [ Glycine max (L.) Merr.] yield by 14.3% and corn yield by 4.5% relative to a water-only control. Polyacrylamide effects on grain yield are possibly attributed to two processes.
