Question 1 of 20
1. Question
2 pointsWhich of the following is NOT correct regarding soils of India.
Correct
Answer: (c)
Justification:
Black soil is known for its self ploughing nature because it is a clayey soil and has much moisture in it. It also develops cracks during summers which exposes it to sunlight and water from rains. Thus it becomes easy to plough it.
The laterite soil is formed under conditions of high temperature and heavy rainfall with alternate wet and dry periods, which leads to leaching of soil, leaving only oxides of iron and aluminum. It lacks fertility due to a lower base-exchanging capacity and a lower content of nitrogen, phosphorus, and potassium. Humus content of the soil is removed fast by bacteria that thrives well in high temperature.
Arid soils generally are sandy in texture rich in calcium carbonates. Hence they have higher pH and are basic in nature. (Hence c is incorrect statement)
Usage of gypsum in alkaline soil helps in reduction in pH of soil. Major Benefits of Gypsum – 1. Source of calcium and sulfur for plant nutrition. 2. Improves acid soils and treats aluminum toxicity. 3. Improves soil structure. 4. Improves water infiltration. 5. Helps reduce runoff and erosion
