John Havlin

John Havlin is a Professor at North Carolina State University specializing in Soil Fertility, with research focused on nutrient management, precision agriculture, and GIS applications for sustainable crop production and environmental stewardship.

Research Interests: Dr. Havlin's work centers on Soil Science and Precision Agriculture, with specific expertise in nutrient management for vineyards and row crops, phosphorus dynamics in waste-amended soils, and spatial analysis of soil-crop systems using Geographic Information Systems. He has pioneered interdisciplinary programs integrating research, extension, and academic training to address agricultural and environmental challenges through precision agriculture methodologies.

Publication Trends: His recent publications (2013-2022) demonstrate sustained focus on long-term nutrient management effects across diverse cropping systems including corn, wheat, soybean, sorghum, and grapes. Key themes include nitrogen and phosphorus fertilization impacts, evapotranspiration measurement techniques, and spatial variability analysis using GIS, all contributing to sustainable agricultural practices and environmental protection.

Labs and Teams: Professor Havlin provides leadership in developing interdisciplinary research, extension, and academic programs in precision agriculture, directing initiatives that apply GIS-based problem-solving to production agriculture, environmental management, and natural resource conservation challenges.
