Fertilizers and the Environment (Grades 6-8)

The amount of land available for agriculture consists of only 1/32 of the surface of the earth. The final lesson in a five-part agriculture series encourages applying the previous lessons to a global perspective on organic farming. Class members analyze the limited resources available, the growing demand, and the importance of food productivity. Scholars also recognize the difference between organic and commercial fertilizers and the role of nutrients in the environment.
