From the Preface: "Judicious and efficient crop nutrition is possible only when functions in plants of different nutrients, their amounts and forms present in soil and reactions that they undergo in soils are well understood and the management practices are fine tuned to the crop plant needs. In most Indian and even foreign universities the knowledge on these three aspects is provided by three different departments, namely, plant physiology, soil science and agronomy and a large number of students don not take courses in all these three departments. This publication attempts to fill this gap and attempts to provide information on basic principles and their application in relation to crop nutrition. This book will be useful to the students, researchers and teachers in agronomy, soil science, plant physiology, microbiology, horticulture, vegetable science, floriculture, microbiology and agricultural extension and others interested in crop production.".…
