DOWNLOAD EBOOKCycling of Mineral Nutrients in Agricultural Ecosystems contains the papers presented in the first international environmental symposium of the Royal Netherlands Land Development Society held at Amsterdam on 1976. The symposium is cosponsored by the International Association for Ecology and Elsevier Scientific Publishing Company. This compilation reflects the exchange of information and ideas by specialists and participants of the symposium. The book is comprised of nine chapters, which cover the following concepts of nutrient cycling in agricultural ecosystems: principles and control of nutrient cycling; description and classification of agro-ecosystems; nutrient cycling data from different countries; and general discussion on nutrient balances, changes in soil pools, manipulations, and future researches. This book also offers potential background and perspectives for further studies on nutrient cycling in agro-ecosystems, presenting a view on what directions future research should take. This volume will be an invaluable reference source for environmental science students and professionals. Research workers in agriculture and other environmental disciplines will also find this book useful.
