ABSTRACT:
Polyacrylamide (PAM) has been shown to be very effective in controlling water erosion from furrow irrigation, but it has not been evaluated for its effectiveness in controlling wind erosion. Laboratory and field wind tunnel tests using several formulations and rates of PAM were conducted to determine its possible use for forming wind erosion-resistant surfaces (crusts). Tests showed that PAM is no more effective than natural rainfall for wind erosion control under general agricultural conditions.
