Abstract

This report presents data showing depletion of zinc and copper and accumulation of molybdenum and boron in four soils during a five-year (1958 to 1963) lysimeter experiment at Riverside. For each element the net change in the soil was calculated as the amount added in the irrigation water minus the amount removed in crops and leachate (drainage water). The lysimeter tanks, which were 4 ft in diameter and 6 ft deep were filled with soil during the winter of 1957–58. Six tanks were used for each soil to provide three treatments, including ammonium sulfate, calcium nitrate, and aqua ammonia as nitrogen sources, and two replications. Phosphorus as dicalcium phosphate was added to all tanks.
