"Agricultural Nitrogen Use and Its Environmental Implications provides a comprehensive, interdisciplinary description of problems related to the efficient use of nitrogen in agriculture, in the overall context of the nitrogen cycle, its environmental and human health implications, as well as various approaches to improve N use efficiency. The book has been divided into six sections and targets graduates, postgraduates, research scholars and policy makers in agricultural and environmental sciences."
