This test covers (almost) everything! We recommend this to everyone from commercial crop producers to home gardeners … anyone who needs to know what’s in their soil! This test measures pH, buffer pH, sum of cations (CEC), base saturation (%), soluble salts, organic matter, nitrate-nitrogen, phosphorus, potassium, calcium, magnesium, sodium, sulfur, zinc, iron, manganese and copper.
