Early mankind experimented with human and animal wastes, seaweed, ashes, menhaden
(a fish used by coastal Native Americans), and other substances to fertilize crops and
increase yields. Over time such trial-and-error attempts to boost yields gave way to the
focused application of science and technology. Chemical engineers have applied their
expertise to chemically synthesize fertilizers, herbicides, and pesticides that promote crop
growth and protect crops from weeds, insects, and other pests. Today, the use of these
products is more important than ever to meet the needs of an ever-expanding population.
