Elsevier Scientific Publishing Company, Amsterdam -- Printed in The Netherlands Book Reviews SOIL WATER ASSESSMENT BY THE NEUTRON METHOD Soil Water A s s e s s m e n t by the N e u t r o n Method. E.L. Greacen (Editor). CSIRO,
East Melbourne, Vict., Australia. 140 pp. $12.00. The book originates from a series of papers, for a workshop on the subject in Australia. It is meant to tell what can be achieved with the neutron m e t h o d but it gives also what precautions must be taken to obtain good results. In ten chapters written by different authors subjects like application fields, theory, instrument design, accuracy, calibration, site selection, data acquisition and health and safety measures are treated. The text is straightforward and concise. Most chapters give a number of data, figures and photographs and are followed by a list of references. The total c o n t e n t reflects the Australian experience with the neutron m e t h o d . It has been applied in water balance studies in the determination of soil water storage and depletion, in soil-plant-water studies and for the determination of soil hydraulic properties and water movement. A subject index, rather u n c o m m o n for a book of this size, does not only help the reader to find the subjects he is interested in, but is also a prove of the care with which the book is prepared.

IRRIGATION SCHEDULING Irrigation Scheduling for Water and Energy Conservation in the 80's. Pro-
ceedings, Irrigation Scheduling Conference, Chicago, Illinois, Dec. 14--15, 1981. ASAE Publication 23-31, American Society of Agricultural Engineers, 1981. 231 pp., US$19.50. ISBN The American Society of Agricultural Engineers (ASAE) hosted a state-ofthe-art conference on irrigation scheduling preceding their annual winter meeting in December, 1981. This state-of-the-art effort was subdivided into three major topic areas: (1) techniques, sofware and strategies for irrigation scheduling; (2) methods and equipment for irrigation scheduling; and (3) application of irrigation scheduling.
