Abstract : Nutrients are sprayed on the leaves to correct nutritional deficiencies of fruit crops. However, when dealing with leaf chemical analysis, one has to wash the leaves with a detergent and chloridric acid solution. This paper evaluates the effect of washing leaves using different concentrations of detergent and chloridric acid on the zinc contents in a mango orchard previously sprayed with this micronutrient.
