| Researcher’s seek a more renewable and natural alternative for water soluble anionic polyacrylamide (PAM), a highly-effective, petroleum-derived polymer used in agriculture to control erosion and reduce water seepage from unlined irrigation structures. This study evaluated two anionic polymers: a bacteria-produced polysaccharide (biopolymer) with 10-20 Mg/mol molecular weight (MW) and 30% charge density, and a PAM (12-15 Mg/mol MW, 30% charge density) to compare their ability to flocculate soil colloids, stabilize soil aggregates, and influence effective hydraulic conductivity (seepage loss). The biopolymer most effectively flocculated the colloids at a concentration of 1 mg/L, but was still 30% less effective than PAM at 1 mg/L and 50% less effective than... |

| This overview will be familiar to anyone who has visited the "PAM page" of the Northwest Irrigation and Soils Research Laboratory's web site. The reader is encouraged to visit that web site, <http://kimberlv.ars.usda.qov/ pampaqe.shtml>, for graphics and photos that were used in this NAICC presentation in Orlando in January, 2001, as well as for other more detailed technical information. PAM has been sold in the United States since 1995 for reducing irrigation-induced erosion and enhancing infiltration. Its soil stabilizing and flocculating properties have also substantially improved runoff water quality by reducing sediments, N, ortho and total P, COD, pesticides, weed seeds, and microorganisms in runoff. The first series of practical field... |
