Answer:
C. It can help conserve Earth's soil and water while increasing soil fertility.
Step-by-step explanation:
"Tilling increases soil erosion and reduces the amount of water that can be absorbed by the soil. This means tilling causes soil and water to be lost to the environment. As a result, farmers have to use more of these resources. No-till farming prevents these losses, so no-till farming can help conserve Earth's soil and water.
Tilling can also make the soil less fertile by removing some microbes and earthworms. No-till farming helps the soil keep the microbes and animals it needs to be productive. So, no-till farming also increases soil fertility."
