The value of wastewater for crop production has been recognized in arid and semi-arid regions of the world including India. Effluent is an important source of irrigation water as well as a source of plant nutrients such as Nitrogen (N), Phosphorus (P), Potassium (K) and trace elements like Sodium (Na), Calcium (Ca) and Magnesium (Mg). Effluent irrigation can eliminate water shortage; reduce the need for chemical fertilizer and enhance the soil fertility. This book is a comprehensive output by authors to analyse "Environment Impact and Assessment Studies of Paper Industry Pollution" and also provides an artistic output with new approaches to use industrial waste water in controlled conditions for crop production in water deficit areas as well as in polluted sites. This book is profusely illustrated with clear diagrams, graphs and in-silico analysis with suggested readings. This comprehensive text has the potential to satisfy the needs of academicians as well as researchers of this concerned field.
