Mineralogy and chemistry of the lowland soil and its sensibilities in the process of lands falls in community Divino Espírito Santo (Amazonas, Brazil)

The study about the mineralogical and chemical lowland soils generate information to compose a current survey about the susceptibility of lowland soil to process Fallen Lands. With this purpose we studied five profiles the banks of the Solimões River, located in the municipality of Iranduba (AM). The information obtained allowed to determine the Neosoil Fluvic the study area has favorable conditions for cultivation with an average pH of 6.2, with high levels of Ca, Mg, K, P, micronutrients and zero Al content, with high levels of C and M. O. in the first layer and a decrease in depth. Thus, Neosoil Fluvic was characterized as Tb eutrophic, with base saturation above 50%, with good CTC. The mineralogy was homogeneous in all profiles, with a predominance of primary minerals: Quartz, Albite and rutile, with low proportions of clay minerals Muscovite, Kaolinite, Muscovite-Illite interstratified and Illite.
