Synergistic effects of anionic polyacrylamide and gypsum to control phosphorus losses from biogas slurry applied soils - ScienceDirect
Excessive application of phosphorus (P) fertilizer to the agriculture soil can lead to the P loss to the aquatic ecosystem. Three soils from different land use (tea, paddy, and vegetable soils) were treated with biogas slurry (BS) at rate of
The hydrolyzed form of polyacrylamide (HPAM), a co-polymer of acrylamide and acrylic acid, is the most widely used anionic PAM in oil and gas development as well as in soil conditioning. 1,9,12,21
Toxicity of Anionic Polyacrylamide Formulations when Used for Erosion Control in Agriculture
A field experiment was conducted to study the effect of an anionic polyacrylamide injection in irrigation water on kelthane runoff and sediment transport from a lima bean soil.
Anionic PAM is widely used in cropland water retention, soil erosion control, and other soil management strategies 5,6,7,8 because of its low cost and stability, and because it is non-toxic and

Effects of anionic polyacrylamide on maize growth: a short term 14 C labeling study, Plant and Soil | 10.1007/s11104-011-0911-y | DeepDyve
The effects of PAM application were directly connected to soil rather than to maize, and could be masked by the non-structural loess. The effects tended to be age and soil-moisture specific, and were modulated by the rhizodeposition processes.
However, high removal rates can be assumed due to complexation with divalent and polyvalent cations and sorption to activated sludge. For anionic polyacrylamide-based flocculants used in WWTPs, it was estimated that approx. 95% of the polymers
Cationic polyacrylamide copolymers (PAMs): environmental half life determination in sludge-treated soil | Environmental Sciences Europe | Full Text
Background Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is
