Consider the following statements            (a) Khadar are Black Soil            (b) Humus content is high in Black soil.            (c) Arid soil is sandy in texture            (d) Laterite soil develops in areas with high temperature and heavy rainfall.            Which of the statement(s) given above is/are correct?

The correct statements are:

(c) Arid soil is sandy in texture: This is true. Arid soils are found in desert areas, which are characterized by low rainfall and high evaporation rates. These conditions lead to a lack of vegetation and organic matter, resulting in a sandy texture.

(d) Laterite soil develops in areas with high temperature and heavy rainfall: This is also true. Laterite soils are typically found in tropical regions, which are characterized by high temperatures and heavy rainfall. The intense weathering in these regions leads to the leaching of silica and the enrichment of iron and aluminum oxides, giving the soil a reddish color.

(a) Khadar are Black Soil: This is incorrect. Khadar refers to the newer, younger alluvial soils found in the floodplains of rivers in India. They are rich in nutrients and are very fertile. Black soil, on the other hand, is rich in iron, lime, and aluminum but poor in nitrogen and phosphorus.

(b) Humus content is high in Black soil: This is incorrect. Black soil, also known as Regur soil, is not high in humus content. It is rich in calcium carbonate, magnesium, potash, and lime but poor in nitrogen and phosphorus.

So, the correct statements are (c) and (d).
