Antonio Mallarino

Dr. Antonio Mallarino is a professor of agronomy and nutrient management research and an extension specialist at Iowa State University. His programs focus on agronomic and environmental issues of nutrient management with emphasis on phosphorus, potassium, lime, and micronutrients. Issues addressed include soil and plant-tissue sampling and testing, fertilizer and manure placement methods to increase nutrient use efficiency and crop yield, use of variable-rate technology, and phosphorous management impacts on water quality. Dr. Mallarino was a prominent member of the team that developed the Iowa Phosphorus Index and is a member of the science team of the Iowa Nutrient Export Reduction Strategy contributing about phosphorus management and water quality. He has calibrated several soil and plant tissue test methods and developed interpretations for Iowa soils.

Dr. Mallarino has been faculty in charge of the Iowa State University Soil and Plant Analysis Laboratory, represents the Iowa Experiment Station at the regional or national committee's Soil Testing and Plant Analysis for the North Central Region (NCERA-13) and Minimizing P Losses From Agriculture (SERA-17/IEG), has served in the oversight committee for the North American Proficiency Testing Program, and has served as Associate Editor of Agronomy Journal and Soil Science Society of America Journal. He is Fellow of the American Society of Agronomy (ASA) and the Soil Science Society of America (SSSA), and, among other awards, received the W.L. Nelson Award for Diagnosis of Yield-Limiting Factors (ASA) and the SSSA Applied Research Award. He has published numerous peer-reviewed scientific articles and technical or extension articles, and has mentored 40 graduate students.
