Degree of compaction and water retention of Latosol submitted to different soil management systems
01/Mar/1999
Soil compaction process studies have more recently involved some soil tests frequently used in soil mechanics. Seeking a better understanding of the application of the Proctor normal test for agricultural purposes, this study aimed to evaluate the soil compaction curve, obtained through this test, and the effect of the degree of compaction on the soil moisture characteristic curves. For the development of this study, a Dusky Red-Latosol (LR), a Red Yellow-Latosol (LV) and a Dark Red-Latosol (LE) submitted to annual […]
Chemistry and mineralogy of soils derived from the Bambuí Group in northern Minas Gerais state, Brazil
01/Dec/1998
Representative soil profiles from the Agroindustrial District of Jaíba in northern Minas Gerais State, Brazil, were morphologically described, sampled and chemically, physically and mineralogically analyzed, to obtain data which could contribute to their improved utilization. Although the parent material was almost the same (Bambuí group limestone), and the apparent physiographical homogeneity (flat relief and deciduous forest), the soils presented great morphological, chemical and mineralogical diversity. From a mineralogical standpoint, illite and kaolinite are common minerals, the latter found even in […]
