What is Polyacrylamide

Polyacrylamide is a synthetic water-soluble polymer made from monomers of acrylamide. Polyacrylamide binds soil particles together. Once soil particles suspended in water are bound together by Polyacrylamide, they settle out, so water has a harder time washing them out of the field. Water -soluble polymers like Polyacrylamide have been known to benefit soil properties for a long time. Recently these polymers have gained renewed attention for their use in reducing irrigation-induced erosion, now that the cost of applying Polyacrylamide has become economically feasible. Other uses of polymers like Polyacrylamide include treatment of municipal water supplies, food packaging, adhesives, a boiler water additive, film former in the imprinting of soft-shell gelatin capsules, adjuvants in the manufacturing of paper and paperboard, and the list goes on and on.
In increasing water infiltration, the check furrows lost 37.5 percent of the water as runoff and 62.5 percent was infiltrated. Out of the total water applied treated with granular Polyacrylamide, 26.5 percent was lost as runoff and 73.3 percent of the water infiltrated into the soil. Out of the total water treated with liquid Polyacrylamide, 29.1 percent was lost as runoff and 70.8 percent of the water infiltrated. Granular Polyacrylamide used as a "patch" was effective to control the loss of sediment and increase water infiltration.
