    Just as plants and animals are classified, they can also be classified according to soil characteristics Scientists divide the earth's soil into 12 main categories However, due to many factors affecting soil development, it is sometimes difficult to maintain this division Soil taxonomy is still a relatively new field, and scientists are still exploring and studying Both ALFISOLS and andisols support the high yield of crops Eluvial soil is distributed in all continents except Antarctica, which is developed under the canopy of temperate deciduous forest, where the underlying clay is covered by deciduous leaves, and then the leaves decompose to produce fertile top layer On the other hand, the ash soil is developed in the area with high level of volcanic activity A high proportion of ash and other volcanic debris makes the soil suitable for carrying large amounts of water and nutrients Aridisols and entisols are two kinds of dry alkaline soils, which mainly exist in desert areas Although proper irrigation sometimes allows them to support crop growth, their natural state does not support a wide range of plant life Dry soil can be found on every continent except Europe The newly formed soil is most concentrated in the Sahara desert of North Africa, and there are some in other places It is developed when some elements in the original soil erode a lot and produce a new soil The water content of the two soils is very high: gelisols and histosols However, the water in the frozen soil thaws during the day and freezes at night, thus subjecting the soil to freezing agitation These soils are found in the upper regions of Canada and Russia, as well as in the high altitudes of the Himalayas Organic soil is full of water, which supports swamps, mainly in Canada and Northern Europe Although the incipient soil and Mollisols are not fully developed, there are some signs of mature soil, including basic stratification They consist of a dark surface layer and a fertile clay layer below This kind of soil exists in different climates around the world Soft soil has a more fertile surface, so it is the most suitable soil for planting all kinds of crops They naturally support wetlands in North America, Eastern Europe and Asia Although Oxisols and Spodosols support specific ecosystems, they are not suitable for growing crops Oxidized soil is mainly found in the rainforests of South America and sub Saharan Africa The ash soil mainly supports the evergreen forests in Canada and Northern Europe These two soils are highly developed and show many color changes due to centuries of erosion Old soils (Ultisols) and Vertisols, although they contain nutrients in the upper layer, are acidic and not fertile Mature soils support grasslands and forests, and many soils in Southeast Asia and the southeastern United States are of this type Although they are more fertile than older soils, they face other problems because of their tendency to expand and shrink precipitation This kind of soil makes it difficult for buildings and gardens to be afforested, because it will crack when it is dry.
