Sjoerd W. Duiker

Professor Sjoerd W. Duiker is a faculty member in the Department of Plant Science within the College of Agricultural Sciences at Pennsylvania State University. His research focuses on soil management practices and their impacts on soil physical properties, crop production, and environmental sustainability. Based at 408 Ag Sci & Ind Bldg, University Park, PA, he maintains an active research program with recent publications spanning soil health indicators, cover crop systems, and tillage effects.

Dr. Duiker's research interests center on sustainable soil management, with specific expertise in no-till farming systems, cover crop implementation, soil compaction dynamics, and soil organic carbon sequestration. His work bridges agricultural practices with environmental outcomes, particularly examining how reduced tillage affects soil physical properties and crop nutritional quality. Recent investigations explore the connection between soil health and human health through compounds like ergothioneine, highlighting interdisciplinary impacts of agricultural management.

Analysis of his 15 most recent publications (2021-2024) reveals a strong focus on soil health indicators (particularly carbon and nitrogen cycling), cover crop performance across diverse environments, and method validation for soil assessment. His collaborative work spans multi-institutional networks like the Long-Term Agroecosystem Research (LTAR) network, with significant contributions to understanding tillage intensity effects on microbial communities and crop quality. Geographically, his research emphasizes Pennsylvania agriculture while contributing to continental-scale assessments.

Dr. Duiker actively engages with agricultural communities through outreach initiatives like the 'Soil Your Undies' challenge, which demonstrates soil biological activity through cotton decomposition. His work has been featured in university communications regarding sustainable agriculture innovations and climate change mitigation through reduced tillage practices.
