Electrical Conductivity
Electrical conductivity, commonly abbreviated EC, measures how readily a solution conducts electricity and is used as an indicator of dissolved salts. In mango growing it can help assess irrigation water, soil extracts, or container media. The sampling and extraction method matter, so readings from different methods are not automatically comparable. EC does not identify which salts are present or measure pH. Investigate high readings alongside water quality, fertilizer use, drainage, and symptoms instead of adding more fertilizer to every pale tree.
