Polyacrylamides (PAMs) are water-soluble, long-chain synthetic organic polymers that, when applied as a soil amendment, purportedly improves infiltration, decreases sediment and agrochemical transport, and improves crop yield. There is a paucity of data, however, on the effect of PAM applied through laylat polyethylene tubing on infiltration, erosion, agrochemical transport, and crop yield for Mid-South soils in furrow irrigated environments. The objective of this thesis was to compile and analyze PAM use in agricultural settings in the United States, and to conduct a 2 year field experiment to assess PAM effects on infiltration, erosion, N and P transport, and corn grain yield on a Dundee silt loam and a Forestdale silty clay loam soil located in Stoneville and Tribbett, Mississippi, respectively. Results indicate PAM has utility to improve infiltration and crop yield in Mid-South production systems, but effects on sediment and N and P transport will be variable and site specific.
