The cation exchange capacity (CEC) of a soil is a key factor to keep soil productive capacity and and to hold the cations added by fertility management in tropical soils. In the clayey oxisols in the Central Amazon the CEC is originally low and is basically due the organic matter charges. The CEC is reduced as consequence of organic matter degradation by inadequate land use systems. The objective of this study was to evaluate the application of different charcoal levels in the CEC in the clayey yellow latossol cultivated with banana. The experiment was carried out at the Research Station of Embrapa Amazônia Ocidental in Manaus – AM. The soil was classified as an clayey Typic Acrothox. The experiment was done using a design with completely randomized blocks with in a confounded factorial (3x3) scheme with 27 treatments. The factors tested were charcoal levels (0, ~13 and ~26T ha-1), phosphorus (167, 334 e 668 kg P2O5 ha-1) and nitrogen (0, 90e 180 kg N ha-1). The source of charcoal used were fine residues produced by canonization of local trees (~700 g C kg-1), super phosphate simple (20% de P2O5) and urea (42% de N). Soil samples were collected in triplicate at each treatment in the depth of 0 - 10 cm. The CEC was determinate using an indirect methods, in which the exchangeable bases were added to the exchange acidity extracted from soils samples. The results shows significance effects (p < 0.05 - Tukey Test) between the level 0 (without charcoal application) and level (13336 and 26672 L ha-1) and those levels do not shows differences between them. Those results shows the potential to use charcoal as soil conditioner to enhance CEC and soil fertility quality in the Oxisols. Another results about the possible influences of the enhance of CEC in the banana nutrition and production will be presented.
