In agriculture, a soil test is the analysis of a soil sample to determine the nutrient and contaminated content, composition and other characteristics such as acidity or pH level. A soil test can determine the fertility, or predicted growth potential of the soil which indicates nutrient deficiencies, potential toxicity from excessive fertility and inhibitions from the presence of non-essential trace elements. The test is used to mimic the function of the roots to assimilate minerals. The expected growth rate is modeled by the Law of the Maximum.
