Consider the following statement:
1. Black soil is known for its porosity.
2. Black soil can produce high agricultural yields.
3. Chernozem is a type of black soil found in Ukraine.
Which of the statements given above is/are correct?
(a) 1 and 2 only
(b) 2 and 3 only
(c) 3 only
(d) 1, 2 and 3
Explanation Statement 1 is correct: Black soil, also known as Regur soil, is known for its porosity, which allows air and water to pass through it easily. The soil has a high clay content that expands when wet and contracts when dry, providing good aeration and facilitating water retention. This makes it beneficial for agricultural purposes.
Statement 2 is correct: Black soil is very fertile, especially for crops like cotton, groundnut, and soybean, due to its rich mineral content and moisture retention abilities. It is well-suited for agriculture, leading to high crop yields.
Statement 3 is correct: Chernozem is a type of black soil found primarily in regions like Ukraine, Russia, and parts of Canada. Chernozem is known for its high organic matter content and fertility, making it one of the most productive soils for agriculture.
