Agricultural chemistry is a subject presenting two quite
distinct lines of study. The study of soils and fertilizers, including the
relation of the plant to its soil food, is almost wholly inorganic and physical.
On the other hand, the study of plants and animals as living organisms is as
distinctly organic and physiological, embracing the greater part of what is
termed Biochemistry. This has led the author to prepare one part of a textbook
of General Agricultural Chemistry with this distinction in view, and to
designate it as Organic Agricultural Chemistry The Chemistry of Plants and
Animals.
