Abstract
Summary: The citrus industry is widespread throughout the country with great economic and social importance for several states. In Pará crops characterized by low use of inputs and adoption of inadequate cultural practices. The study aimed to evaluate, by means of foliar diagnosis, the nutritional status of orchards of the micro Guama, under three soil management practices. Six representative orchards, all with plants of sweet orange 'Pera' (Citrus sinensis (L.) Osbeck) grafted on Rangpur lime (Citrus limonia Osbeck), taking into consideration three managements were selected. For all samples of leaves with fruit branches 2-4 cm in diameter in the different quadrants of plants and were collected in two seasons. The biggest nutritional limitations of the orchards were P, regardless of the time in low and medium levels of management, while limitations on K occurred mainly in low management, in both seasons. Regarding micronutrients, Zn, by deficiency in plants, introduced himself as the most limiting, followed by Mn, while for Fe it was found high and excessive level.
