معرفی
Dr. Marshall D McDaniel is an Associate Professor in the Department of Agronomy at Iowa State University, specializing in soil-plant interactions and sustainable agriculture. His research focuses on soil health, cover crops, nutrient management, and agroecological systems. He leads the McDaniel Lab, which explores regenerative farming practices and their impacts on soil microbiology and crop yields. Dr. McDaniel collaborates with multiple graduate students and researchers, including Summer J. Bjorn, Reid Barker, and Malcolm St. Cyr. His work integrates field studies, spatial modeling, and interdisciplinary approaches to address agricultural challenges like nitrogen dynamics and tile drainage impacts on water quality. He also contributes to initiatives like the Iowa State University Long-Term Agroecological Research (LTAR) Experiment. His research spans topics from crop rotation effects on soil carbon to the role of anaerobic digestate in enhancing soil organic matter.
Education and affiliations include roles in the Sustainable Agriculture and Environmental Science interdepartmental programs. He advises students on projects such as cereal rye cover crop BMPs and soil health principles. Publications highlight his expertise in soil greenhouse gas emissions, microbial biomass, and decomposition dynamics. Dr. McDaniel’s lab website (https://www.soil-plant.com/) and McDaniel Lab site provide further details on ongoing projects and outreach efforts.
Key research projects include evaluating cover crops’ effects on corn yield drag, developing spatial models for nutrient management, and investigating soil health practices’ double-impact on water quality. His work emphasizes translating scientific findings into actionable strategies for farmers, such as DIY soil health assessments and optimizing nitrogen rates for maize.
