Soil and Container Media Electrical Conductivity Interpretations

E. A. Hanlon, B. L. McNeal, and G. Kidder

This document is about interpreting electrical conductivity (EC) measurements in soils and container media to manage soluble salts from fertilizers, irrigation water, and storm events. It explains how excessive salts affect plant growth, provides guidelines for testing and interpreting EC values, and offers practical recommendations for leaching salts and preventing salt accumulation in landscapes, crops, and containerized plants.
