CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): There has been a large shift to sprinkler irrigation in the USA. Beyond labor considerations, this has been driven by soil and water resource conservation. Some crops, however, do not tolerate wet canopies (e.g., seed beans). Further-more, the capital cost, energy use, and technological requirements are out of the

PAM has been long used to control soil erosion in furrow irrigation (Sojka and Lentz 1997). In Jordan, Abu-Zreig et al. (2007) have shown that land application of PAM highly reduced soil loss and

Polyacrylamide – A Method to Reduce Soil Erosion, G98-1356-A
Furrow irrigation, however, is a major contributor to soil loss. With nearly half of the irrigated acres in Nebraska under furrow irrigation, reducing soil erosion on these acres could help maintain topsoil for future generations.
Sprinkler Irrigation Runoff and Erosion Control with Polyacrylamide — Laboratory Tests J. Kristian Aase,* David L. Bjorneberg, and Robert E. Sojka ABSTRACT Many semiarid and arid soils are prone to irrigation-induced ero-sion. Polyacrylamide (PAM) greatly reduces erosion from furrow irrigation. We hypothesized that PAM applied via sprinklers will
Polyacrylamide efficacy for reducing soil erosion
Values of TRO with 20P and 40P were not increased at a 10% slope compared to 0P. Slope was not a factor in reducing RO. Applications of 40P for all slopes had significantly greater RO than either 0P or 20P. Polyacrylamide reduced SL for all slopes.
crusting as well as erosion. Polyacrylamide is also used to stabilize steep slopes in construction, highway cuts, and other disturbed soils. The economics of PAM use can encourage its use in many instances and discourage its use in others. Polyacrylamide is very cost effective in furrow irrigation systems where it can be applied at low
