Description :
A soil test determines the soil’s nutrient supplying capacity by mixing soil during the analysis with a very strong extracting solution (often an acid or a combination of acids). The soil reacts with the extracting solution, releasing some of the nutrients. As soil supplies most of the mineral nutrition for higher plants through the plant’s root system, the extracted nutrient concentration is evaluated based on research that relates plant utilization to soil nutrient concentration.
