Abstract

The polymer, polyacrylamide (PAM), is a high molecular weight, chemical anionic polymer that is prescribed and used for irrigation improvement in row crops primarily in the United States. A field research study was conducted in 2014, 2015 and 2016 in Northeast Arkansas to evaluate how addition of PAM in furrow irrigation affected soil erosion, water infiltration, movement of nutrients and sediments, and crop yields in cotton (Gossypium hirsutum). Overall results from the study were mixed. Sediment loss was similar among treatments. Irrigation advancement rates were not significantly different. No differences in crop yield were observed associated with PAM. Differences in results from previous positive observations in Western United States cropping systems may be explained by precipitation, soil type, cropping systems, and precision leveling common in the Midsouth region. From this study, PAM did not show promising results to be a widespread farm management practice in Midsouth with furrow irrigation.
