Handbook of Plant Nutrition

Allen V. Barkeris a professor at the University of Massachusetts, Amherst, where he has taught subjects of organic farming, soil fertility, and plant nutrition for 50 years. His research has addressed nitrogen nutrition of crops with emphasis on ammonium nutrition and on the interactions of nitrogen with other elements in affecting crop growth and nutrient accumulation. He is a member of editorial boards of several journals that publish articles on plant nutrition. He wrote Science and Technology of Organic Farming, which is also published by CRC Press, and with David J. Pilbeam edited the First Edition of Handbook of Plant Nutrition. David J. Pilbeamhas over 30 years' experience of research and teaching on plant nutrition and physiology at the University of Leeds, UK. He has published particularly on the physiology of uptake and assimilation of inorganic nitrogen by plants but also on the accumulation of other elements. As well as research on the physiological aspects of plant nutrition, David has published on more agronomic aspects of plant growth and nutrition, including work on intercropping, novel crops, and agroforestry. Together with Allen Barker, David edited the First Edition of Handbook of Plant Nutrition in 2007. He is currently a member of the editorial board of Journal of Plant Nutrition.
