When one kind of plant grows in soil, it uses up certain nutrients. Other kinds of plants use up other types of nutrients.

In nature, the many different kinds of plants balance each other out. But on a farm, usually only one kind of crop is grown. Growing this same crop again and again can make the soil infertile, meaning nothing will grow there.

What might fix this problem?

1 - Plow the soil

2 - Spray pesticides on the soil

3 - Leave the field bare for a few years and don't allow any plants to grow on it

4 - Grow a different crop on the soil every year
