This book is a treatment of the proper and judicious use of fertilizers with emphasis for semi-arid and arid regions in the world. Enough background information is given on soil chemical processes and plant nutrition to provide the reader with the understanding of the rates of plant food needed and allows for the proper selection for fertilizer materials and methods of application.

The publication is most complete on those subjects important to low or erratic rainfall areas. Conciseness has been achieved by eliminating soil fertility considerations which are not pertinnent to arid and semi-arid regions.The following are discussed: (a) nitrogen, (b) phosphorus, (c) potassium, (d) secondary and micronutrients, (e) special fertilization practices and multinutrient fertilizers, and (f) determining fertilizer requirements.
