ResumoWe aimed assess the soil fertility and nutritional status of pear orange plants in different orchards in the State of the Amazonas.The most soils showed: i) acidic pH and with high levels of Al; ii) low content of organic matter and base saturation; iii) low levels of P; K, Ca, Mn, Zn and B. The plants were deficient in Ca (86%), K (62%), S (52%), Mn (100%), Zn (86%), B (80%) and with excess of N (81%) and P (51%).We conclude that there is an urgent need to adjust the soil fertility in orange orchards aims to increase fruit yield and quality.
