A farmer clears an area of all grass and bushes to create a dirt field to plant crops. Three years later, the farmer notices that the nutrient-rich topsoil is no longer in the field. Which solution could help the farmer keep nutrient-rich topsoil in the field so that healthy crops can grow?

• Use specialized machines to plant seeds without disturbing nearby soil.

• Dig deep ditches around the outside of the field to catch rainwater that flows over the soil.

• Harvest crops in the field early before their roots use nutrients in the soil.

• Plant less crops in the field to decrease the number of insects that live in the soil.
