Rotating crops with legumes or grass pastures to improve soil fertility is referred to as lay farming.
In lay farming, certain crops, especially legumes or grass pastures, are alternated with other crops. This practice helps in replenishing the soil with nitrogen and other essential nutrients, ultimately improving its fertility. Legumes, for example, can fix nitrogen in the soil, reducing the need for chemical fertilizers.
The correct option is (D): Ley farming.
