705 MANURE
pH 1:5 pH (Water 1:5)
Determination of manure pH.
Summary: This method determines the pH of the liquid from a slurry of manure, using 1 part sample and 5 parts deionized water. The method is generally reproducible within 0.2 pH units.

715 ESTIMATED SOLUBLE SALTS (ECe)
EC (Water 1:5)
Determination of manure ECe.
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).
