Abstract

The effects of leaf-washing techniques for removal of surface contaminants were evaluated with regard to possible mineral losses that might affect orange-leaf analysis. Techniques used were: (1) nonwashed, (2) rubbing in detergent and rinsing, (3) rubbing in detergent, then dipping in 3% HCl and rinsing. Concentrations of N, P, K, Ca, and B in the leaves were not significantly affected by the washing procedures. Concentrations of Mg, Na, Cl, Zn, Mn, Cu, and Fe in or on the leaves were affected. No significant leaching losses of nutrients from the leaves were found due to washing treatments.
