A new approach to the nutritional status of manganese in oil palm plants cultivated in the eastern Amazon

Little is understood about the nutritional status of manganese (Mn) in oil palm (Elaeis guineensis Jacq.), further research needed to provide technological support for greater productivity, especially on dynamics accumulation, recycling, immobilization and export. Thus, objective this work was evaluate immobilization, exportation efficiency Mn use plants at different ages. The experiment carried out a completely randomized design, with seven treatments (plant age: 2, 3, 4, 5, 6, 7, 8 years planting) four replicates. leaflets male inflorescence were, vegetative reproductive organs highest concentration, respectively. accumulation nutrient tree crown predominated stipe through all years. bunch exported amount Mn, older plants. immobilizes recycles, more than exports, large Mn. increased as function age crops organs. In conclusion, demand altered age, altering recycling
