Sandy and rocky soil is often found in the drier regions of the western United States, such as deserts and arid landscapes. These soils have low moisture retention and organic matter, making them less fertile and more prone to erosion.
The Piedmont zone of the Western Ghats typically has red soil, which is a type of laterite soil. This type of soil is rich in iron and aluminum oxides, making it well-drained but nutrient-poor. Red soil is commonly found in regions with high rainfall and warm temperatures, such as the Western Ghats.
In Jharkhand, the types of soil found include red sandy soil, red and yellow soil, laterite soil, and alluvial soil. Red sandy soil is predominant in the western part of the state, while red and yellow soil is found in the central and eastern regions. Laterite soil occurs in the southern part, and alluvial soil can be found along river banks.
Nutrient-rich soil is usually found in regions with a mix of decomposed organic matter like forests, grasslands, and wetlands. This type of soil is often found in areas that have a high level of biodiversity and microbial activity, which helps break down organic matter and enrich the soil with nutrients.
The parent material is usually found in the C horizon of a soil profile. This horizon is located below the A and B horizons and consists of partially weathered rock or unconsolidated material from which the soil has developed.
Laterite soil is found in the western coastal region due to the warm and wet tropical climate, which accelerates the process of leaching and weathering of rocks. The heavy rainfall and high temperatures in the region contribute to the formation of laterite soil by promoting the breakdown of parent rocks rich in iron and aluminum.
