Soil Science

Laterite soils are typically red due to iron oxides (1) and are suitable for crops like cashew nuts and tapioca (4). They are generally poor in nitrogen and potash (making 2 incorrect) and are found in tropical regions with high rainfall, not Rajasthan (making 3 incorrect).

Black soil is best suited for growing cotton.

Tea and coffee plantations require well-drained, slightly acidic, and nutrient-rich soil, which is typically found in hilly or mountainous regions.

Black soil, also known as regur soil, has high clay content and is known for its self-ploughing property, where it swells when wet and develops deep cracks when dry.

Lateritic soil is formed in tropical regions with high temperatures and heavy rainfall, which leads to intense leaching of silica and leaves behind iron and aluminum oxides.

Red soil is widely distributed across several states in India, including significant portions of Andhra Pradesh, Karnataka, and Tamil Nadu, due to the weathering of ancient crystalline rocks.

Cotton plant is grown in black soil and at places with warm climate, as it needs higher temperature for growth and good yield.

The big pieces of the soil in the ploughed field are known as crumbs.

Laterite soil is found in regions with high rainfall and temperature, such as the Western Ghats in Maharashtra, Kerala, and Karnataka.

It helps open pores so that water percolates out, evaporates and cools the water inside.
