Abstract: One hundred ninety-five soil horizons from 50 benchmark soil profiles in California were analyzed for total aluminum, magnesium, manganese, nickel, cobalt, copper, iron, molybdenum, and zinc by acid decomposition, resin column separation, and colorimetric methods. Half of the soil series contain low and possibly deficient levels of one or more of the following essential elements: cobalt, copper, molybdenum, manganese, and zinc. Four soil series profiles identified with alkali basins contain relatively high, and probably toxic, levels of molybdenum.
