WebSoils form naturally by weathering; if protected from erosion, sound management can maintain or enhance their nutrient levels and textural characteristics. Rates of soil erosion … WebThe central concept of Oxisols is that of soils of the tropical and subtropical regions. They have gentle slopes on surfaces of great age. They are mixtures of quartz, kaolin, free oxides, and organic matter. For the most part they are nearly featureless soils without clearly marked horizons.

WebOXISOLS, ULTISOLS, AND VERTISOLS The low latitudes are dominated by three soil orders: Oxisols, Ultisols, and Vertisols. These soils have developed over long time spans in an environment with warm soil temperatures and plentiful soil water either in a wet season or throughout the year. WebThe oxisols are the highly weathered soils of the tropics. like the ultisols, but they have lost most of the weatherable materials. Silicates are usually present as quartz, and the dominant colloids are Fe,Al oxides and hydroxides. The latter material is called laterite and the soils have been classically known as lateritic soils. See some OXISOLS
