Question

Which of the following affect the fertility of soil badly?

• A. Excessive use of fertilizers
• B. Composting
• C. Excessive use of pesticides
• D. Practice of growing the same crop over and over

Answer 1

Answer: (A), (C), (D)

Practice of growing the same crop over and over

While fertilizers and pesticides help increase yield by providing nutrients needed for plants and protecting crops from pests and insects, they are proven to be harmful to the soil and the crops when used excessively. The soil becomes less fertile and this leads to low yield of crops.

Growing the same crops over and over keeps draining the soil of nutrients, thus reducing its fertility.
