A Guide to Interpreting Irrigation Water Analysis

While a few aspects of irrigation water quality have a direct impact on plants, the primary goal of water analysis is to judge the effect of the water on the soil, and ultimately on the plants grown on the soil. As such, much of the interpretation of the water analysis is based on a prediction of the consequences for the soil. The interpretation of the test results is, in many cases, dependent on the intended use of the water. Some plant species and production systems may have much different requirements or tolerances. The interpretation guide lists some of these conditions and will help you evaluate your results.
