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.

Does polyacrylamide improve erosion resistance?

Extensive research conducted by Abrol et al. (2013); Mamedov et al. (2021); Shi et al. (2021) has also explored the beneficial effects of polyacrylamide in terms of improving erosion resistance, ensuring a conducive environment for plant growth, and more.

Is polyacrylamide an organic compound?

Through analysis, it is speculated that this substance may be polyacrylamide, an organic compound that does not participate in chemical reactions within the soil but enhances soil water stability through its bonding properties. Detailed analysis results can be found in the microanalysis section in the following sections.

Does anionic polyacrylamide reduce soil erosion?

Anionic polyacrylamide (PAM) has the potential to reduce soil erosion through soil conditioning. However, a comprehensive study about its effectiveness especially when applied combined with other amendments have rarely been conducted in the tropical highland climatic conditions, such as in Ethiopia.

Is polyacrylamide a good soil conditioner?

However, as these solutions are proposed, numerous doubts and opposing opinions are emerging. Polyacrylamide (PAM), also known as “soil conditioner”, “soil amendment” and “soil stabilizer” in soil science (Gilda Dell'Ambrogio and Wong, 2019), is commonly used to modify the unfavorable and damaged characteristics of soil.

Does polyacrylamide hydration improve geotechnical properties of saline soil?

SEM analysis revealed that inorganic compounds underwent chemical reactions with ions in the soil, generating a substantial amount of hydration products. When combined with the polyacrylamide, a synergistic effect substantially improved the geotechnical properties of saline soil.
