Bench terraces are constructed at a slope gradient of

Correct option is C

• Slopes between 2-10% can be managed with simpler conservation methods like contour bunding or strip cropping.

• Slopes greater than 10% require bench terraces to control runoff and prevent soil loss.

• Slopes exceeding 33% may require additional reinforcement techniques such as stone walls or vegetative barriers to prevent terrace collapse.

1. Purpose:

   • Reduces soil erosion.

   • Enhances water conservation.

   • Converts steep land into arable land.

2. Types of Bench Terraces:

   • Level Bench Terrace – Used in areas with moderate rainfall for rice and vegetables.

   • Inward Sloping Bench Terrace – Used in high-rainfall areas to store water.

   • Outward Sloping Bench Terrace – Used in low-rainfall areas to drain excess water.

Crops Suitable for Bench Terraces:

1. • Rice, maize, pulses, vegetables, and fruits.
