Drip irrigation controls soil salinity under row crops

Blaine Hanson, Warren E. Bendixen

Abstract

Keeping soil salinity low in the root zone is crucial to growers of salt-sensitive crops. This study investigated patterns of soil salinity under surface and subsurface drip irrigation. High soil salinity occurred midway between drip laterals for both irrigation methods and above the drip tape for subsurface drip irrigation. Rainfall leached the salts from the zones of high salinity for both irrigation methods.
