The electrical conductivity (EC) unit is commonly employed for analyzing fertilizer component concentrations in hydroponic growth’s nutrient solution or root zone. This involves measuring the electrical conductivity of a solution to determine the cumulative ions necessary for plants (e.g., NO3-, Fe3+) and ballast components (e.g., Na+). The EC value is usually expressed in either millisimens (mS/cm) or microsimens (µS/cm).
