QUANTITATIVE SPRAY DEPOSITION ANALYSIS USING A LITHIUM SALT.
Lithium can be used as a tracer to evaluate spray deposits on crop foliage. In multiple tests, solutions of lithium sulfate and water were sprayed on crop leaves. The leaves were washed with deionized water and the wash water analyzed for lithium by atomic absorption spectrophotometry. A quantitative estimate of spray solution applied to the leaf was then established and verified.
