Abstract

Soil chemists have centered their work for many years on ·two allied problems: first, to understand the mechanisms by which nutrients are sup­ plied to plants; second, to estimate the ability of a particular soil to supply a crop with its nutrients. The two aims go hand in hand. One man may follow both in a single piece of work. Or perhaps one man may study equilibria i n which pho sphate ion is adsorbed on ferric compounds, while a colleague devises a practical test for estimating the amount of such adsorption by shaking a soil with a fluoride solution, which breaks the link between iron and phosphate. T,his review deals with the principles of availability. How­ ever, many of the articles reviewed are partly or wholly concerned with the practical question, "How much of this element can a given soil supply?" Innumerable methods of extraction exist for answering this practical ques­ tion. While they do not constitute our subject, from time to time one of them will throw light on the underlying principles. The major principles of availability have already been set out in the An­ nual Reviews of Plant Physiology (1, pp. 1-6; 2). In the
