Conteúdo: | Agricultural production in the 1ropics is frequent1y limited by low soil fertility. Many 1ropical soils are relatively poor in soil organic matter (SOM), as well as frequently have low cation exchange capacity (CEC), low pH, low calcium (Ca), and phosphorus (P) contents. The existence of an anthropgenic enriched dark soil horizons ( Amazonian Dark Earth (ADE) shows that infertile soils may be 1ransformed to permanent fertile and productive soils. The ADE's fertility is most likely linked to an anthropogenic accumulation of P, Ca (from bane apatite) and black carbon that retain those added nutrients. The objective of this study was evaluate the efIect of levels of charcoal residues applied combined with a source of mineral phosphorus and nitrogen in the production and nutrition of banana plants in an yellow Oxisol in the Central Amazon. The experiment is being carried at Experimental Research Station of Embrapa in Manaus - Brazil. The experimental design is a confounded factorial with three factors (charcoal, phosphorus and nitrogen) in three levels, each treatment is composed with six plants. The charcoal and fertilizer are applied annually. The parameters measured are nutrient in the banana leaves and soil chemical and physical parameters to monitot the banana nutrition and soil fertility. The harvest and weight of banana bunchs are dane weekly. The results show significant differences in the soil fertility paramaters evalutead.
