Two common bean cultivars were grown on soil samples of an Oxisol (LR) and Alfisol (PVp), with and without fertilizer, subjected to 3 levels of compaction, and confined in 3,8 liter pots. The objective was to observe the diferential behavior of a bean cultivar considered tolerant and another sensible to the Al and the low P level in the soil. The harvested data permit to verify that the tolerant cultivar presents a greater root and a smaler shoot development (in weight), with the tendency to a preferential accumulation of P, K, Mg, Zn and Fe by the roots and of Ca and Mg by the top, independent of soil type, fertility and compaction level. Besides this presents a greater sensibility to compaction on substract with a higher fertility level, when considered the accumulation of dry matter of the shoot.
