Abstract
  • Accumulation of excessive salt in irrigated soils can reduce crop yields, reduce the effectiveness of irrigation, ruin soil structure, and affect other soil properties. This publication is designed to help you evaluate the kind and amount of salts present in soils and to select management alternatives. This publication describes the soil tests commonly used in evaluating salt-affected soils in the western U.S. and gives general guidelines for test interpretation. It will help you do the following: • Understand how sodium, calcium, and magnesium affect soil structure • Request appropriate soil analyses from commercial laboratories • Interpret soil test data • Choose appropriate practices for maintaining productivity in salt-affected soils, including: – Leaching – Amendments (kind and rate) – Crop selection – Cultural practices (e.g., tillage and bed shaping to improve seed germination) • Estimate costs and benefits of management practices
  • Published November 2007. Reviewed July 2013. Please look for up-to-date information in the OSU Extension Service Catalog: http://extension.oregonstate.edu/catalog
