Estimated Soluble Salts (ECe)

EC (Water 1:5)

Summary

This method measures the electrical conductivity (ECe) in the liquid from a slurry of manure, using 1 part sample and 5 parts deionized water. The electrical conductivity of the extract is reported. The method has a detection limit of approximately 0.1 dS/m (mmhos/cm).

Sample amount requested:  30 g

Questions concerning limited sample size can be answered by the UC Davis Analytical Laboratory.
