Answer 2

A "team of ICRISAT" scientists invented that ‘Countour bunding’ is a technique by which farmers can control soil erosion. It helps to maintain the moisture of the soil and brings a 20% increase in net income.

Explanation:

• “Countour bunding” is a technique that reduces soil erosion and water runoff. Andropogon and Vetiver are the grasses which help to protect soil erosion.
• Farmers use these grasses for crop production. It is a low-cost technique that increase the crop yield without expanding farmlands.
