Pot trials with fertilized and non fertilized soil samples of the A horizon from an Oxisol (LR) and an Alfisol (PVp) , confined in 3,8 liter pots, and cropped with two common bean cultivars, were conducted in greenhouse. The soil samples were subjected to compaction forces, and mantained with a soil water tension between 100 and 300 mbars . The beans were harvested at the flowering stage and at 67 days after emergency (maturity). It could be verified a diferential variation in dry matter production due to the genotype, the cultural stage, fertility and compaction levels of the soils. In general, at the end stage of the culture, the dry matter accumulation is related with the soil macroporosity. It seems to exist an ideal zone for maximal accumulation, below and above of which, there is a tendency to decrease. The major influence of the compaction occured on the fertilized pots. In the above ground part occured the general tendency of increase on the Mg concentration (up to 26.3%), besides on Ca and N, and the decrease on the K level. In the roots the tendency was of increase on the Mg and the K, and reduce on the N concentrations. At the end stage it could be verified a general tendency in increase on accumulation of Mg and the decrease on K an( N in the drave ground part, and the decrease on and the Ca, P and N in the roots, considering the Oxisol. In the Alfisol, it could be verified a general tendency in increase on the accumulation of Mg and N, besides the decrease on K In the shoots, and the decrease on Ca and K in the roots.
