The purpose of this research was to assess the effects of replacement of native ?Cerrado? vegetation (NV) into croplands on soil chemical, physical and microbial properties. This research was carried out on a farm under Rhodic Hapludox soil with different types of agricultural managements systems, and it was used a NV to compare the systems. The experimental design was set up in completely randomized with five treatments and five repetitions. The treatments adopted were several agricultural management systems as follow; NV; CS_Crop system; LS_Livestock system; ICLS-4_Integrated crop-livestock system with four years of implementation; ICLS-8_Integrated crop-livestock system with eight years of implementation. It was assessed some chemical, physical, and microbial parameters in the soil, as soil pH, P content, exchangeable cations, cation exchange capacity, base saturation, cations saturation, soil organic carbon (SOC), soil bulk density (SBD), aggregate stability, microbial biomass carbon (MBC), basal breathing, and microbial quotient. The replacement of NV to ICLS decreased SOC, MBC, soil aggregate stability and increase of SBD. The ICLS improved ?Cerrado? soil fertility over time adoption. This integrated system increased the quantity of exchangeable K+ and P content in ?Cerrado? soil. The ICLS-8 showed soil environment nearby the NV. Even the difficulty in obtaining the same physical and microbial condition of NV, the results of this research point out quite important observations, because just no-till system is not enough to obtain improvement of soil quality and the ICLS can return the soil properties close to native ?Cerrado? vegetation.

Soil acidity is a major yield-limiting factors for bean production in the tropical regions. Using soil acidity?tolerant genotypes is an important strategy in improving bean yields and reducing cost of production. A greenhouse experiment was conducted with the objective of evaluating 20 dry bean genotypes for their tolerance to soil acidity constraints. An Inceptisol soil was amended with dolomitic lime (2 g dolomitic lime kg?1 soil) to achieve low acidity (pH = 5.9) and without lime (zero lime kg?1 soil,) to achieve high acidity (pH = 4.8) levels to evaluate bean genotypes. At both acidity levels, genotypes differed significantly in shoot dry weight and grain yield. Shoot dry weight and grain yield were significantly decreased at the high acidity level compared to the low acidity level. Grain yield was more sensitive to soil acidity than shoot dry weight. Hence, grain yield was used in determination of tolerance index (GTI) to differentiate the range of soil acidity tolerance among bean genotypes. Based on a GTI value, 55% of the genotypes were classified as tolerant, 40% classified as moderately tolerant, and the remaining were grouped as susceptible to soil acidity. The genotype CNFC 10410 was most tolerant and genotype CNFP 10120 was most susceptible to soil acidity. Number of pods and grain harvest index were significantly and positively associated with grain yield. The improvement in grain yield in low acidity may be related to reduction of toxic levels of soil aluminum (Al3+) and hydrogen (H+) ions by lime addition. At harvest, soil extractable phosphorus (P) and potassium (K) increased with the reduction of soil acidity, and this might have contributed to the better nutrition of beans and lead to higher growth.
