EFFECTS OF LEACHING SOLUTION PROPERTIES AND VOLUME ON TRANSPORT OF METALS AND CATIONS FROM A RIVIERA FINE SAND

摘要

A column leaching study was conducted using a Riviera fine sand(Loamy, siliceous, hyperthermic, Arenic Glossaqualf), sampled at 30 cm increments to 150 cm depth, from a commercial grapefruit grove to vealuate the effects of leaching solution properties on the leaching of Zn, Cu, Mn, Fe, Ca, and Mg in seven pore volumes of leachate. The concentration of Cu in the leachate was highest in the surface horizon (0-30 cm), indicating its limited transport down the soil profile. The concentration of Zn was significantly greater in the 30-60 cm depth sample than at the other depths.
