Sloping seedbeds—to minimize the soil salinity hazard to germinating seeds—have been designed to permit conversion to normal flat-topped beds after the seedlings are established.

Sled designed for forming sloping beds was built by co-operator James Simons of Brawley, Imperial County.

The study reported above is part of the research being conducted by the Salinity Laboratory, United States Department of Agriculture, Riverside, California, and the University of California.
