Soil salinity refers to the concentration of soluble salts present in the soil. These salts accumulate over time through various natural and human- induced processes, and when present in high concentrations, they can severely impact agricultural productivity and plant health.

The primary measurement used to assess soil salinity is Electrical Conductivity (EC), typically expressed in deciSiemens per meter (dS/m). This measurement works because dissolved salts increase the soil's ability to conduct electrical current; the more salts present, the higher the conductivity reading. Understanding where your soil falls on the salinity spectrum is crucial for effective management. Here's the standard classification system adapted from the NRCS Soil Survey Handbook:
