Brazil Determination of leaf sampling techniques to assess the nutritional status of Barbados cherry (Malpighia emarginata D.C.). Abstract — Introduction. Research on the mineral nutrition of Barbados cherry is scarce. Leaf sampling techniques for this crop are unknown. Leaf analysis, associated with the deter-mination of the nutrient availability in the soil, can provide reliable orientation for the estab-lishment of fertilizer programs. For a correct interpretation of the nutritional status, it is impor-tant (1) to evaluate the seasonal variation of nutrient contents in the leaves, (2) to determin
