The American Society of Agricultural Engineers has named Robert Sojka and Rodrick Lentz as co-recipients of the 2003 ASAE Award for the Advancement of Surface Irrigation. The award, which honors individuals who successfully demonstrate and publicize the effective use of surface irrigation, was presented at a recent ASAE luncheon.
Soil scientists with the USDA-ARS Northwest Irrigation and Soils Research Laboratory in Kimberly, Idaho, the two winners are being recognized for their contributions to research and development of pioneering technology that has controlled erosion of surface-irrigated land.
Sojka and Lentz led a highly productive research program that has led to the development of cost-effective practices for the application and use of anionic polyacrylamide (PAM). PAM technology allows furrow irrigation to continue in areas where sprinkler irrigation and other erosion control alternatives are cost prohibitive. It has been widely adopted in the western United States and other areas of the world and has conserved millions of tons of topsoil on the furrow-irrigated fields.
