Abstract

Urban growers want to know about soil fertility and potential soil contamination. We investigated if a commonly used soil fertility test, the Mehlich-3 nutrient extraction, could be used for both of these purposes. The Mehlich-3 soil test has traditionally been used test to measure soil fertility (Mehlich Commun Soil Sci Plant Anal 15:1409–1416, 1984). It is routinely available at soil test laboratories and is typically not cost prohibitive. While it has been used to measure plant nutrients, it is relatively simple for laboratories to include Pb in the suite of elements that are analyzed. Our results indicate that the soil fertility test results can provide a soil test screening value for Pb. Using a routine extraction provides a cost effective and rapid way for urban farmers to assess whether their soil is contaminated, in addition to evaluating soil nutrient levels.
