Total Dissolved Solids (TDS) & Methods to Reduce Them
Total Dissolved Solids (TDS) & Methods to Reduce Them

“,Total dissolved solids, (,TDS,) is the term used to describe the inorganic salts and small amounts of organic matter present in solution in water.” The principal constituents are usually calcium, magnesium, sodium, and potassium cations and carbonate, hydrogencarbonate, chloride, sulfate, and nitrate anions.

Interpreting Irrigation Water Tests

Total Dissolved Solids, (,TDS,) ,TDS, is a measure of all of the dissolved substances in water. ,TDS, and conductivity levels in water are typically closely correlated and a conversion factor of approximately 640 is often used to predict ,TDS, from conductivity which is easier to measure. The formula is ,TDS, (mg/L) = 640 * EC (mmhos/cm).
