Study on interpreting water quality analysis reports

A water source is suitable for irrigation when individual parameters are below thresholds that would negatively impact plant growth and quality or compromise irrigation systems.

The quality of irrigation water is crucial to develop nutrient programs that are compatible with the crops' needs.

The first step to a good interpretation is properly collecting samples. In brief, collect the sample close to the source; let the water run for a few minutes before pouring into the container; use a clean container; be consistent in how you collect samples; and send the sample(s) immediately. 

A summary of the interpretation for each parameter is included in this article. All the parameters, except pH, below the threshold are optimum for irrigation. When any element is above the optimum level, adjust the nutrient program. If plant essential elements are above the levels required by the crop, then select and apply fertilizers that do not have such an element. In extreme cases, revere osmosis or blending with other water sources might be required.
