Allen Barker

Allen Barker is a Professor in the Department of Plant and Soil Sciences at the Stockbridge School of Agriculture, University of Massachusetts Amherst. He has been a faculty member since 1962, progressing to full Professor in 1976, and has held significant administrative roles including Head of Department and Graduate Program Director. His work bridges teaching, research, and extension in plant and soil sciences.

His research interests focus on:

• Plant and soil nutrition
• Soil fertility and nutrient cycling
• Organic farming systems and fertilization
• Phytoremediation of heavy metals (e.g., zinc, arsenic)
• Sustainable horticultural and agricultural practices
• Linkages between soil nutrients and human health

The recent articles (2006–2014) reflect a strong trend in sustainable nutrient management, particularly in organic systems, with emphasis on zinc and phosphorus dynamics, compost evaluation, and the use of plants like Indian mustard and fescue for soil remediation. His work integrates laboratory and field studies with practical applications in agriculture and environmental protection.

His scientific awards include:

• Environmental Quality Research Award (1975)
• Marion Meadows Award (1977)
• Outstanding Teacher, Food and Natural Resources (1992–1993)
• Outstanding Professor, Stockbridge School (1997)
• Hewlitt Fellow (2000)
• Outstanding Associate Editor, ASA (2012)

He has advised graduate students and coordinated the Honors program for over four decades. His extensive service includes editorial roles and leadership in professional societies such as the American Society of Agronomy and Soil Science Society of America. He has also authored the comprehensive Handbook of Plant Nutrition and a book on organic farming.

Allen Barker has led or contributed to research teams focusing on nutrient management and soil health, often collaborating across disciplines and institutions. His lab has explored compost efficacy, nutrient loading, and sustainable ornamental crop production, contributing to both academic knowledge and practical agricultural solutions.
