Excerpt from Fertilizers: The Source, Character and Composition of Natural, Home-Made and Manufactured Fertilizers, and Suggestions as to Their Use for Different Crops and Conditions
There is no question as to the desirability of the use of commercial fertilizers on most farms, though the methods now generally practiced are such as to indicate the very great need of a better understanding of what the functions of a fertilizer are, of the terms used to express their composition and value, of the kind that shall be used, and the time and method of application for the different crops under the varying conditions that exist.
In the preparation of this book, therefore, it has been the aim of the author to point out the underlying principles and to discuss, in the light of our present knowledge of the subject, some of the important problems connected with the use of fertilizer materials. The subject is a large one when considered in all its bearings, and much must necessarily be omitted in a book intended for the general reader as well as the student.
