ARCOVERDE, S. N. S.; CORTEZ, J. W.; OLSZEVSKI, N.; SALVIANO, A. M.; GIONGO, V.The inadequate agricultural management in the semiarid region of northeastern Brazil, associated with the fragility of most soils, has caused degradation of the quality of this resource. This study aimed to evaluate the quality of Quartzipsamments under different uses through the multivariate analysis of chemical and physical attributes. Five areas were selected: four of them with agricultural use (onion, banan...

LOURENTE, E. R. P.; SILVA, E. F. da; MERCANTE, F. M.; SERRA, A. P.; PEIXOTO, P. P. P.; FERREIRA, R. C. F.; ENSINAS, S. C.; NETO NETO, A. L.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 ...

FEITOZA, J. R.; MENDES, A. M. S.; OLSZEVSKI, N.; CUNHA, T. J. F.; CORTEZ, J. W.; GIONGO, V.The purpose of this study was to evaluate the effects of organic farming of wine grapes under physical and chemical characteristics of Ultisol Brazil?s northeastern semiarid region. The samples of soil were collected from the row and interrow of the farming and from the fallow area, at the depths of 0.0-0.10, 0.10- 0.20, 0.20-0.30 and 0.30-0.60 m. The samples were collected at six and twelve months after the cu...
