  • Does polyacrylamide reduce soil erosion?
  • Soil amendments like anionic polyacrylamide (PAM), which is a synthetic polymer, non-toxic, and environmentally friendly can reduces runoff and soil erosion (Sojka et al., 2007 ), although, its effectiveness in reducing runoff and soil loss can be enhanced when PAM is applied in combination with lime and gypsum (Kebede et al., 2025 ).
  • Does polyacrylamide reduce soil nutrient depletion?
  • Polyacrylamide (PAM) mitigates soil nutrient depletion and increases nutrient utilization; however, the effect of PAM combined with other amendments have not been tested much under field condition.
  • Does gypsum improve soil aggregation?
  • Hence, applying PAM in mixture with sources of calcium electrolyte (Ca 2+ ), such as gypsum or lime, enhances its effectiveness in reducing runoff and soil loss, consequently improving soil aggregation ( Lee et al., 2010 ).
  • Does gypsum reduce soil loss?
  • This finding is consistent with other research showing that amendments (PAM, gypsum, and lime) reduce soil loss to a greater extent than they reduce runoff (kebede et al., 2025). Treatments reduced both seasonal runoff and soil loss compared to the control, but no statistically significant difference was noted among most treatments ( Fig. 5 ).
