报告人简介:

Robert Horton is a Distinguished Professor in the Agronomy Department at Iowa State University. His program addresses soil physical processes and soil physical properties, with a focus on coupled heat and mass transfer in soil. His fundamental work on coupled heat and mass transfer in soil has greatly enhanced understanding of the role of soils in the following topic areas: climatology (the importance of surface energy partitioning); water quality (the impacts of soil water and chemical movement); agricultural production (the impact of the soil environment on seed and root functions); ecosystem products and services (the impact of the soil environment on microbial function and gas exchange); and environmental investigations (thermal and mass flow methods for remediation of soil pollution).  His singular contributions include a comprehensive theory of coupled heat, water and chemical transfer in soil, quantifying in situ unsaturated soil hydraulic conductivity and dynamic subsurface water evaporation, and devising and validating a method to control fertilizer nitrogen leaching.  To reach these goals his program includes laboratory and field measurements, sensor development, theory development, and numerical modeling.

报告人简介:

Dr. Bradley Miller leads the Geospatial Laboratory for Soil Informatics, which is primarily focused on digital soil mapping. In a broader sense, Dr. Miller's research seeks to advance the quantitative evaluation of spatial variations in environmental processes that affect the distribution of soil properties, with special consideration for how those variations impact environmental quality and sustainable crop production. This work integrates geographic information science and soil science to develop, improve, and curate high-quality soil geodatabases. Quantitative spatial analysis of landscape structure (patterns) improves understanding of our natural environment. Using digital terrain analysis and other non-invasive data collection techniques, this research is producing more accurate and higher resolution soil maps. In turn, these maps improve land management decisions as well as crop and environmental modeling applications.
