Question

9. Why should we grow cover crops after a crop has been harvested?
o. Why is soil a valuable natural resource?​

Answer 1

Answer:

For the first question:

There should always be cover crops even after a crop has been harvested. Cover crops are almost like a backup plan in case the main crops get attacked by bugs or crows, the rain isn't too good, or other problems. Cover crops can replace the ruined crops and keep a famer's business going, and can provide food for the family.

Now here is the answer to the second question:

Soil is a very valuable natural resource because it helps crops grow healthy and well. Soil has special nutrients in the soil that the crops use as energy and food. Sometimes, if there isn't enough nutrients in the soil, farmers use fertilizer. Although it is an effective way, it can also be harmful to rivers and streams.

I hope this helps!
