All organisms require nitrogen to live and grow. The movement of nitrogen between the atmosphere, biosphere, and geosphere in different forms is described by the nitrogen cycle. This book covers various aspects of the N-cycle such as chemistry, biology (enzymology, molecular biology), physics, applied aspects, and others.

"The impetus for this book comes from the members of Action 856 of ESF COST of the European Community under the title 'Denitrification in Agriculture, Air and Water Pollution' (http://www.cost856.de)."--P. xv
