Maintaining soil health is fundamental to successful crop production and ecosystem sustainability. To enable effective management soil health must first be measured and then monitored and so the authors review and evaluate how soil organisms can be used to fulfil this role. This book is essential for all soil scientists and consultants. It is of particular relevance to those involved in soil health monitoring and maintenance as well as those undertaking soil remediation. It is also important reading for agronomists, ecologists and environmentalists. This book is a comprehensive and effective resource for all those working to sustain healthy soils.

The objective of this volume is to present a full and critical spectral data coverage of the entire major fields relating to tetraphenyl and analogous porphyrins, their precursors, catabolic derivatives, and related systems electronically.The porphyrins are an important class of naturally occurring macro cyclic compounds that play a very important role in the metabolism of living organisms. They have a universal biological distribution and were involved in the oldest metabolic phenomena on earth. Without porphyrins and their relative compounds, life as we know it would be impossible and therefore the knowledge of these systems and their excited states is essential in understanding a wide variety of biological processes, including oxygen binding, electron transfer, catalysis and the initial photochemical step in photosynthesis.

Nuclear Magnetic Resonance (NMR) is based on the fact that certain nuclei exhibit a magnetic moment, orient by a magnetic field, and absorb characteristic frequencies in the radiofrequency part of the spectrum.
