Learn about salinity and related concepts

Learn about salt in the root zone

Where to go for more information

Much of the material in this module is based on information in Chapters IV and IX of a literature-review document prepared earlier as a companion to the present document. You can find a copy of the literature review on the same CD-ROM disk that houses this document.

The following reference books also provide valuable information about salinity in the root zone:

  • Ayers, R.S., and D.W. Westcot. 1985. Water Quality for Agriculture. FAO Irrigation and Drainage Paper 29, Rev. 1. Food and Agriculture Organization.
  • Hanson, B., S.R. Grattan and A. Fulton. 1993. Agricultural Salinity and Drainage: A Handbook for Water Managers. Water Management Series publication number 93-01, University of California, Davis.
  • Tanji, K.K., editor. 1990. Agricultural Salinity Assessment and Management. ASCE Manual No 71, American Society of Civil Engineers.
