In order to reach high productivity, banana crops must be cultivated in places with favorable climatic factors that present soil with good chemical and physical properties. The present work has the objective to evaluate the chemical and physical properties of soil cultivated with Prata dwarf banana crops (AAB) in three levels of productivity. A total of 96 commercial banana crops were selected in the North of Minas Gerais. The banana crops were divided in three levels of productivity: low productivity (< 25 t ha-1 year-1), average productivity (25 the 32 t ha-1 year-1) and high productivity (> 32 t ha-1 year-1). In each selected banana crop, soil samples were collected for chemical and physical analyses. Leaf samples of each banana crop were collected in 20 plants. In the foliares samples were determined the N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn proportions. It was verified that the content of Ca, K, P, organic matter, the values of electric conductivity, CTC, the percentage of saturation per bases (V%), and the amount of clay and silte present were significantly greater in the banana crops of high productivity soil. It was verified that in the banana crops of high productivity soil the amounts of Ca, K and Mg corresponded to 82%, 5% and 13% of the base saturation, respectively. There was no difference among the foliar contents of nutrients in the three banana crops levels of productivity.
