Soil Tests - Electrical Conductivity & Organic Matter

TEST 1: Electrical Conductivity (EC) value provided by the lab, is a measurement that relates to the amount of salts in your soil sample (salinity). It is reported in deciSiemens per meter (dS/m) units. After you check out, you will receive an email confirmation with an order number. Please note this number on your soil sample submission. TEST 2: The Organic Matter (OM) is determined in the lab using the Loss on Ignition (LOI) method. It is reported in % of weight. Monitoring changes in soil organic matter should be of interest for all farmers wanting to improve crop productivity on their farms.
