SoilDevelop uder tropical and subtropical regions
Answers
Explanation:
The term ‘tropical soils’ is not as geographically inclusive as might be inferred from the name. From a pedological point of view, the term traditionally does not include all soils occurring in tropical environments, soils of low‐latitude deserts typically being excluded, as are some pedogenically young (poorly developed) soils. The inclusive and exclusive terminologies are somewhat inconsistent and their applications depend of specific reference points, most commonly referring to extreme degrees of biochemical weathering for prolonged periods of time. Tropical soils are thus defined principally by climate and stage of genetic development with particular examples dependent upon parent material and topography. Identification of tropical soils is partially dependent on the classification system and its interpretation of the convergence of the factors of soil formation that come together to produce mantles of intensely weathered materials
Tropical soils are formed in areas with high annual temperature and rainfall. Even though the savanna and the tropical rainforestes are VASTLY different in organisms and extent, they both have a climate that results in deep, highly weathered soils. The intense weathering causes these soils to be nutrient poor and low in organic matter.
CLIMATE
The savannas are grasslands that have several months of dryness, followed by a rainy season. A majority of the soils in this area are Alfisols and Ultisols. These soils are very old and low in fertility, but since there is a dry season, more of the nutrients can stay in place.
