This book covers nearly 4500 terms of interest to all scientists and researchers dealing with fertilizers. A comprehensive reference book, the Encyclopedia covers up-to-date information on fertilizers: behavior in soil, chemical and physical characteristics, physiological role in plant growth and soil fertility. Production methods for a wide range of fertilizers are also described. An editorial board has worked on revising the entries to the encyclopedia from 2005-2007 to ensure all necessary entries were included.
