The agricultural use of polyacrylamide, PAM, as an additive in irrigation water has grown rapidly since commercial introduction in 1995 because it improves water infiltration and reduces erosion

Polyacrylamide in Agriculture and Environmental Land
Polyacrylamide (PAM), which is a hydrophilic polymer, has been used in the field of agriculture for nearly half a century due to its ability to increase infiltration and decrease irrigation
We assessed the effects of BC, synthesized BP and anionic PAM on the decomposition of 14 C‐labelled maize residues and on their stabilization in aggregate fractions in sandy and sandy loam soils. Polyacrylamide and BP were applied at 400 kg ha −1 and BC was applied at 5000 kg ha −1 , and the soils were incubated for 80 days at 22°C.
Polyacrylamide Removes Microorganisms and Nutrients
Lande et al. (1979) applied 25 mg PAM kg-1 soil and reported that half life of an AMD in agricultural soils was 18-45 hr. There have been mixed, and sometimes conflicting, reports regarding the effects of PAM application on bacterial biomass levels in soils and waters.
The simplest method of using superabsorbent polymers or polyacrylamide (PAM) in agriculture is to apply them directly onto the soil. However, it was proved that such a manner of application leads to a decrease in the strength parameters of soils [29,30] and a reduction in their permeability.

Polyacrylamide (PAM) is a generic chemistry term that refers to a broad class of compounds, and they are often used as soil conditioner. Significant sediment reductions have been observed in furrow irrigation when small amounts of PAM are applied in irrigation water.
December 10, 1998. Twenty-five shareholders/customers met all day with the ARS project leaders at the ARS, NWISRL, Kimberly, Idaho location. Objectives of this meeting were to identify (1) immediate, 1-3 yrs, and future needs, 5-10 yrs, of irrigated agriculture, (2) select 5-10 high priority needs, and (3) identify solutions or obstacles to solving each of the high priority needs.

- What is polyacrylamide (PAM) & how is it used?
- Apart from that, it is also used in paper making, and as a chemical intermediate for the production of other chemical products. During Q2 2025, Polyacrylamide (PAM) pricing in North America demonstrated a significant upward trend, driven by a combination of market dynamics and external factors.
- Is polyacrylamide (PAM) a good buy in Asia-Pacific?
- In the Asia-Pacific region, the market of Polyacrylamide (PAM) displayed mixed sentiments during the second quarter of 2025. At the beginning of the quarter, the market of PAM witnessed a decline in price trends.
- Why are polyacrylamide (PAM) prices rising?
- Based on our analysis of the US market for the first quarter of 2025, it is evident that Polyacrylamide (PAM) prices have experienced a sharp increase due to the rise in demand from downstream industries and feedstock cost pressures. Despite domestic production operating rates remaining firm, inventory levels have dropped.
- How is polyacrylamide produced?
- Commercially, PAM is produced by hydration of Acrylonitrile (ACN) to produce Acrylamide and then cross-linking polymerization of Acrylamide that produces PAM. During production, Acrylamide is always advised to be handled with care due to its high toxic nature, although after polymerization polyacrylamide become non-toxic.
