What are the types of soils?
What will be an ideal response?
Answer: Soil types relate to the different soil-forming factors in different locations. Forest soils usually contain less organic matter but more clay-enriched B horizons than do grassland soils. Desert soils contain the least organic matter of all soils and clay accumulates slowly in the B horizon because of limited chemical weathering. Desert soils and grassland soils in relatively dry areas contain calcite in the B horizon. Rainforest soils are very strongly weathered and usually infertile because of a nearly complete dissolution or organic matter and mineral nutrients. Highly weathered tropical soils are the source of bauxite, which is mined to produce aluminum. Wetland soils are composed primarily of organic matter. Immature soils, with only faintly developed horizons, form where there has been insufficient time for significant weathering. Most immature soils indicate unstable landscapes or areas too cold for weathering reactions to occur effectively.
