Synopsis This is a unique, reader-friendly dictionary on soil fertility, fertiliser use and integrated nutrient management. It primarily focuses on the terms, topics and aspects of direct importance to present day agriculture. The dictionary covers not only fertilisers but all sources of plant nutrients (mineral, organic, bio). It also covers all plant nutrients (macro and micro) and provides a broad-based, inter-disciplinary coverage dealing with environmental aspects as well. Two unique features of this dictionary are that (i) in most cases actual examples are cited after explaining a term and (ii) in many cases, terms or processes are explained with the help of diagrams.
