Standardized methodology for determination of a plant soil substrate that reflects the electrical conductivity plants experience.
electrical conductivity, plant substrate
Electrical conductivity is commonly tested along with pH for plant substrates at time of use, as well throughout the growth cycle. Electrical conductivity of a sample is highly influenced by both the extent of dilution by water during sample preparation currently varying from "glistening to 1:1 or 1:1.5 volume to volume ratio. Specification of the method being used during testing is critical to interpretation of electrical conductivity (EC) results.
