Soil, Fertilizer & WateringCan recent sprays distort mango leaf-test results?
Yes, residues from nutrient sprays and some crop-protection materials can elevate measured elements and complicate interpretation. Report the product history and application dates to the laboratory before collecting samples. Do not assume washing at home will remove every contaminant or preserve a valid sample. Follow the laboratory's preparation and waiting instructions, and flag unexpected results that conflict with the tree's condition and prior analyses.
