What is Arenosols soil?
Arenosols are sandy-textured soils that lack any significant soil profile development. They exhibit only a partially formed surface horizon (uppermost layer) that is low in humus, and they are bereft of subsurface clay accumulation.
How are Arenosols formed?
These Arenosols are zonal soils; they result from intense and prolonged dissociation of weatherable minerals and translocation of the weathering products. Figure 2shows an Albic Arenosol developed in sandstone weathering in Queensland, Australia.
Where is latosol soil found?
tropical rainforests
Latosols, also known as tropical red earth, are soils found under tropical rainforests which have a relatively high content of iron and aluminium oxides. They are typically classified as oxisols (USDA soil taxonomy) or ferralsols (World Reference Base for Soil Resources).
Is Vertisols good for agriculture?
The natural vegetation is a function of the soil climate. Most Vertisols are well suited for mechanized farming if there is plenty of rainfall or irrigation water and if suitable management practices are followed.
What is the meaning of latosol?
Definition of latosol : a leached red and yellow tropical soil.
What type of soil is Vertisols?
clay soils
Vertisols are churning heavy clay soils with a high proportion of swelling clays. These soils form deep wide cracks from the surface downward when they dry out, which happens in most years. The name Vertisols (from L. vertere, to turn) refers to the constant internal turnover of soil material.
What is latosol soil?

How are latosol soils formed?
Laterisation is the dominant process in forming latosols. Laterisation is a combination of deep leaching and chemical weathering. These combine to dissolve all mineral except iron and aluminium. If soil erosion removes the loose topsoil, iron and aluminium is exposed.
Which crops grow in red soil?
The lowermost area of red soil is dark in color and very fertile, while the upper layer is sandy and porous. Thus, proper use of fertilizers and irrigation yields high production of cotton, wheat, rice, pulses, millets, tobacco, oil seeds, potatoes, and fruits.
