All the richness of the soil is used. For Exercise 3, here is a simple: Organic farming means crops growing with natural fertilizers instead of chemical ones. Yhe natural fertilizer which is natural waste from animals does good to soil. It makes the soil richer in minerals while chemical fertilizers damage the soil, leaving chemicals fertilizers in the ground for a long time and killing both helpful and harmful bacteria and pests. Organic farmers keep the soil rich and healthy by changing plants every two or three years, planting different crops in different layers and planting grass between crops to prevent wind or water from carrying away the soil.
