Produktbeschreibung
Excerpt from Soils and Fertilizers In many of the high schools and other secondary schools into which instruction in agriculture was introduced a few years ago there has been such a development of the subject that one general text is no longer adequate. In these schools some of the more important phases of the subject now receive a degree of attention that calls for specialized texts. This is particularly true of the secondary agricultural schools and the normal schools. It was with the hope of meeting this need, and also of contributing to the demands of short courses in agriculture and of summer courses for teachers, that this book was written. The attempt has been made so to present the subject that the pupil who has no knowledge of chemistry or other natural science will be able to understand it. No chemical symbols or formulæ have been used. Use has been freely made of a limited number of names of chemical substances contained in commercial fertilizers which contribute to the nutrition of plants. These, however, are terms with which the pupil can familiarize himself as readily as with the geographical and other names that he has already mastered. Following each chapter are field and laboratory exercises, designed to illustrate in a concrete manner the teachings of the text. There are more of these than any one teacher will probably find it expedient to have his class perform, but the considerable number and variety of exercises will make it possible for any school to afford the necessary facilities for performing some of the demonstrations.
