Abstract

Polyacrylamide (PAM) has received widespread attention in the last 3 .4 years as a potential new tool for virtually halting irrigation-induced erosion in furrow irrigated agriculture when added in small amounts to the advance phase of water application. When used properly, 3-7 lbs of PAM per acre per year can reduce erosion from typical furrow irrigated fields in Idaho an average of 94%. Because PAM in irrigation water retards surface sealing, it also generally increases net infiltration and lateral movement of infiltrated water. Season-long infiltration totals for PAM-treated fields in Idaho have averaged 15% higher than non-treated fields.
