A field experiment was carried out in a Yellow Oxisol to investigate the effects of biosolids application on soil chemical properties and on banana leaf's nutrient concentration during the first cropping cycle. Soil analysis (pH, organic matter, resin P, exchangeable Ca and K, available B, DTPA-extracted micronutrients, and heavy metals) and index-leaf analysis (B, Cu, Fe, Mn, Zn, Cd, Cr, Ni, and Pb) were evaluated. Biosolids can completely substitute mineral N and P fertilizer to banana growth. Soil exchangeable K and leaf-K concentration must be monitored in order to avoid K deficiency in banana plants. No risk of heavy metal (Cr, Ni, Pb, and Cd) concentration increase in the index leaf was observed when biosolids were applied at the recommended N rate.
