Answer 2

Terrace farming is the best method for preventing soil erosion in an agricultural area.

Explanation:

• Therefore, the correct choice of the asked question is Option (D).

• Terrace farming is a method in which steps called terraces are built on mountain and hill slopes.

• Terrace farming helps in preventing soil erosion. When there occurs rainfall, the soil nutrients and the plants that are washed away by the rainfall falls or flows to the next terrace instead of getting washed away somewhere else. This way soil erosion gets prevented.

• Terrace farming is mainly used to grow crops like vegetables, fruits, cereals, wheat, rice, pulses, maize, paddy, medicinal plants, etc.

• Terrace farming is practiced in states such as Haryana, Uttaranchal, Meghalaya, Himachal Pradesh, Punjab and also in plains of Uttar Pradesh.
