Polyacrylamide (PAM) use in irrigation for erosion control has increased water infiltration and reduced soil erosion. This has improved runoff water quality via lower concentrations of nitrogen, phosphorous, and pesticides, and decreased biological oxygen demand. Since non-toxic high molecular weigh …

This study discusses the effects of gypsum and polyacrylamide (PAM) application on infiltration and erodibility of a Japanese acid soil. Acid Kunigami mahji soil (sedimentary rock derived, Typic Hapludult) from Okinawa was packed into an acrylic plastic box, and simulated rainfall of 40 mm h −1 was applied.

Does polyacrylamide application rate affect soil erosion and nutrient loss?

A laboratory research experiment under simulated heavy rainfall with tap water was conducted to investigate the effects of anionic polyacrylamide (PAM) application rates (0, 0.5, 1.0, and 2.0 g m −2) and molecular weights (12 and 18 Mg mol −1) on runoff, soil erosion, and soil nutrient loss at a slope of 5°.

Can polyacrylamide soil amendments be used on a farm?

Polyacrylamide (PAM) soil amendments are increasingly used to remediate these degraded lands with the potential benefits on soil health and crop production. However, the scientific evidence of farm-scale use of one-time versus repeated application of PAM has not been reported.

Why is polyacrylamide used in irrigation for erosion control?

Polyacrylamide (PAM) use in irrigation for erosion control has increased water infiltration and reduced soil erosion. This has improved runoff water quality via lower concentrations of nitrogen, phosphorous, and pesticides, and decreased biological oxygen demand.

Can polyacrylamide improve soil fertility and crop yield?

Improving soil fertility and crop yield through application of soil amendments such as polyacrylamide (PAM), lime, gypsum, and biochar to agricultural land has emerged as a strategy in numerous countries (Agegnehu et al. 2016; Lee et al. 2015; Sojka et al. 2007). PAM is non-toxic and environmentally friendly (Entry et al. 2008; Song et al. 2018).

Does polyacrylamide increase teff yield?

Overall, this study demonstrated that the use of polyacrylamide (PAM) with biochar on slightly acidic, and with lime on moderately to strongly acidic soils increased teff yield with highest net benefit and marginal rate of return than application of PAM, gypsum, lime, biochar, and farmyard manure alone or PAM + gypsum treatments and the control.
