Mineral salts in soil comprise the most important ingredient of nutrition for plants. The variety of mineral salts which plants require for growth are taken up from the soil, or in the case of some aquatic plants, from the surrounding water.

The whole subject matter has been divided into 10 chapters, which includes historical background, proceeding from an account of experimental materials and methods to a description of the physico-chemical process by which ions move in non-living systems. A summary of the effects of various external and inherent factors on the course of absorption is followed by a consideration of the relationship between uptake and metabolism. The location of accumulation mechanisms in cells is discussed in detail, and this leads to an account of salt absorption and transport in vascular plants. Finally, there is a brief description of the soil as a source of mineral nutrients and a discussion of the physiology of salt tolerance.

It is hoped that the book will be quite useful for the Under graduate and Post-graduate students of Agricultural Universities, Students of Botany, Plant Science, Teachers, Scientists and Research workers in the field of Mineral Nutrition.
