Q. Consider the following statements:
- Latosols are the soils of humid tropical and equatorial regions
- Podzol soils are associated with the regions of cool humid climate with a fairly well-distributed rainfall
Which of the above statements is/are correct?
Answer:
Both 1 & 2
Notes: Both statements are correct:
- Latosols (also known as Oxisols) are indeed the soils of humid tropical and equatorial regions. They are highly weathered soils that have lost most of their soluble nutrients due to the intense leaching caused by heavy rainfall in these regions. These soils are often red or yellow in color and have a low fertility, making them less suitable for agriculture without proper management and fertilization.
- Podzol soils are associated with regions of cool humid climates with a fairly well-distributed rainfall. These soils are commonly found in boreal or taiga forest regions, where there is a cool climate and ample moisture. Podzol soils have distinctive horizons, with a leached, grayish-white or light-colored layer (the E horizon) on top of a darker-colored layer (the B horizon). The leaching process is influenced by the acidity of the soil, which is related to the presence of coniferous trees that produce acidic organic matter.
So, both statements are accurate descriptions of the respective soil types and their associated climates.
