HIS monograph deals in considerable detail with a soil problem which, in recent years, is becoming of the utmost importance to vast agricultural areas. Dr. Kelley's researches are exhaustive and they provide a basis for dealing with the alkali soil problem which has heretofore been lacking. The book covers the problem and its solutions in terms of ion exchange — a field in which Dr. Kelley is renowned — and comparisons are drawn to the condition as it exists in the western United States and in Russia where much work has been done on the same subject. Entirely new material and a completely up to date approach to the subject is found in the rather^ detailed consideration of: (a) the effects of spJuBle sal^Mon» the soil itself and the resulting consequences Oikifjhè grbtvtnlof crops.
AND
RECLAMATION
(b) the relation of irrigation to alkali soils, especially in regard to the spread of alkali in soils. (c) the relation between the kind of salts that accumulate in alkali soils in their effect on the natural transformations to which alkali soils are subjected. (d) the various means by which alkali soils of different types can be effectively reclaimed and . . . (e) the methods of farm management by which the farmer may take full advantage of the new knowledge on the subject to the end that the reclamation can be made permanent. Chapter 7 gives a full account of how to make practical use of the ideas in new knowledge set forth in this book. Furthermore, the basic researches of Hilgard and Gedroyz are discussed in great detail and all the pertinent evidence is presented and evaluated. This monograph will be essential to all soil chemists, agricultural chemists and agronomists and should rightly take its place beside the author's previous work "Cation Exchange in Soils." 1951, ACS Monograph, 168 pages, $5.00
