FAQ (Frequently Asked Questions)

What is the difference between the Bulk EC and PWEC (Pore water EC) readings? PWEC is the agricultural standard reading and a measurement for the electrical conductivity of water in the pores of your soil; Bulk EC is the electrical conductivity of the bulk soil (Soil, Air, Water).
