Question

Which of the following is a disadvantage of tilling?

• A. It allows the roots to penetrate deep into the soil.
• B. It helps in the growth of microbes and earthworms present in the soil.
• C. It loosens the soil making it prone to erosion during floods.
• D. It brings nutrient rich soil to the top.

Answer 1

The correct option is C

It loosens the soil making it prone to erosion during floods.

Despite all the advantages of tilling, it poses one demerit i.e. it makes the top soil loose. Thus, making it prone to erosion by floods or air (if the soil lacks sufficient moisture, it can be eroded by winds also).
