Answer 1

For restoring soil fertility the suitable among them is rotation of crops.

Answer 2

D. Rotation of crops is suitable for restoring soil fertility.

Crop rotation:

• Crop rotation is the process of planting several crops in succession on the same piece of land in order to enhance soil health, maximize nutrient content, and reduce insect and weed load.
• Examples of this approach include rotating crops such as broccoli, winter wheat, and sweet corn, wheat, fallow ground, alfalfa, potatoes, grass seed, and tiny grains, among other combinations depending on a number of variables.
• A "method of cultivating different kinds of crops in repeated succession on the same land" is referred to as crop rotation.
• Crop rotation has a number of additional economic and environmental advantages.
• Crop rotation is also beneficial for long-term soil and farm management.

Terrace farming:

• A terrace is a section of sloped land that has been divided into a succession of progressively smaller flat surfaces or platforms that resemble steps in order to facilitate more efficient farming.
• Terracing is the name given to this style of landscaping.
• Soil erosion is significantly reduced by terraces because they lessen the volume and speed of water traveling across the soil surface.
• Thus, terracing allows for greater crop intensification than would otherwise be achievable.

Shifting agriculture on hill slopes:

• An agricultural practice known as shifting cultivation involves temporarily cultivating a parcel of land, abandoning it, and then shifting to another plot while the post-disturbance fallow vegetation is allowed to grow naturally.
