Fertile Soils Grow More
When a crop is harvested, it takes from the soil the nutrients that helped it grow and that give it taste and color and healthfulness for humans and animals. Unless those nutrients are replaced, the size and quality of successive crops will fall – just when world population is rising and people everywhere insist on more and better food. To satisfy all those people, each acre of land must produce more, and that means increased and more balanced use of fertilizer.
