Cracking Behavior of Polyacrylamide-Treated Saline Soil
Abstract: Polyacrylamide (PAM) is a water-soluble polymer with the ability to enhance a soil’s stability. PAM is currently being used to prevent irrigation-induced erosion and enhance the infiltration in farmland soil. To improve the compaction properties of the saline-soil-based filling
PAM is currently used as a soil conditioner on ~800,000 ha 33 of irrigation land in the U.S., corresponding to 900–18,000 tons of PAM per year. PAM binds with soil particles through

Polyacrylamide and Water Quality Effects on Infiltration in Sandy Loam Soils Husein A. Ajwa* and Thomas J. Trout ABSTRACT Slow infiltration rates constrain effective and economical irrigation in some sandy loam soils in California. Polyacrylamide (PAM) has in-creased soil infiltration in some areas, especially in soils high in clay or silt.
Polyacrylamide in Agriculture and Environmental Land
Anionic polyacrylamide (PAM) has been sold since 1995 to reduce irrigation‐induced erosion and enhance infiltration. Its soil stabilizing and flocculating properties improve runoff water quality by reducing sediments, N, dissolved reactive phosphorus (DRP) and total P, chemical oxygen demand (COD), pesticides, weed seeds, and microorganisms in runoff.

PAM in Furrow Irrigation, an Erosion Control Breakthrough
Furrow irrigation-induced erosion is nearly eliminated by small additions of water-soluble polyacrylamide (PAM) to irrigation water. PAM is an environmentally safe industrial flocculent widely used in municipal water treatment, paper manufacturing, food processing and other sensitive applications.
Depositional seals, formed when turbid waters infiltrate into soils, lead to a reduction in soil hydraulic conductivity (HC) and enhance runoff and soil erosion. Since clay size particles constitute a dominant proportion of depositional seals, soil texture and clay mineralogy play a significant role in determining the seal’s hydraulic characteristics.
CA2464299A1 - Polyacrylamide suspensions for soil
A stable aqueous suspension of water-soluble polyacrylamide particles is in a saturated solution of an ammonium salt. The polyacrylamide particles are characterized by a particle size of about - 150 mesh, and preferably - 270 mesh, with - 400 mesh most preferred. The suspension is at least about 2.5 % by weight polyacrylamide. When the ammonium salt is ammonium sulfate, PAM concentrations as

Using more than the recommended amount of PAM will not increase effectiveness 86 and may clog soil pore spaces, decreasing infiltration. 92 The maximum application rate for critical areas is 200 pounds per acre, per year, of pure form polyacrylamide. 86 To be effective, PAM needs a source of divalent cations, such as Ca +2 or Mg +2. 95 In many
- 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.
- Can anionic polyacrylamide (PAM) be used to treat animal waste?
- The application of anionic polyacrylamide (PAM) to soils and/or vegetative treatments may also provide a cost-effective way to dramatically reduce bacteria and nutrient loads in animal waste effluent and thereby reduce pollution in surface and ground waters receiving these effluents.
- 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.
- Is polyacrylamide a good management practice?
- Relatively low cost, high reduction of irrigation-induced erosion and soil loss, ease of use and integration, make Polyacrylamide a best management practice worth looking into by any agricultural operation. How is PAM applied and what forms does it come in for application?
