| Landscapes formed on Barreiras Formation sediments occupy signifi cant area on Brazilian territory. Many of these landscapes have highly intensive agricultural use, dueto favorable climate and topography. The objective of this study was to characterize and to compare soil profi les situated on non-dissected coastal plains from southern Bahia to Alagoas, occurring under natural vegetation (forest) and agricultural use. Seven soil profi leswere analyzed and data from six soil profi les obtained in other works were incorporated. Particle size distribution, organic C (OC), Al, Ca, Mg, Al+H, K, Na, P, Fe, Ti and Si were determined. Clay mineralogy was analyzed by X-ray diffraction. Soil profi les occur on fl at relief, have yellow color, weak small to medium... |
