Donald E. Todd spends much of his time researching Soil water, Ecology, Environmental chemistry, Agronomy and Nutrient. His Soil water research is multidisciplinary, incorporating elements of Watershed and Ecosystem. His Watershed research integrates issues from Soil science, Water potential and Precipitation.
His work on Throughfall, Organic matter, Soil contamination and Terrestrial ecosystem as part of his general Ecology study is frequently connected to Mercury, thereby bridging the divide between different branches of science. His Environmental chemistry study integrates concerns from other disciplines, such as Soil organic matter, Soil carbon, Humus and Soil chemistry. In the field of Agronomy, his study on Growing season overlaps with subjects such as Nyssa sylvatica.
Donald E. Todd focuses on Soil water, Hydrology, Nutrient, Throughfall and Precipitation. His studies link Environmental chemistry with Soil water. His Environmental chemistry research is multidisciplinary, incorporating perspectives in Acid rain, Soil chemistry and Soil horizon.
Many of his research projects under Hydrology are closely connected to Ridge with Ridge, tying the diverse disciplines of science together. His Nutrient study combines topics in areas such as Forestry, Agronomy and Animal science. His Precipitation study combines topics from a wide range of disciplines, such as Canopy, Understory, Water potential and Phenology.
His primary areas of investigation include Soil water, Hydrology, Ecology, Nutrient and Soil carbon. His research integrates issues of Environmental chemistry and Organic matter in his study of Soil water. The various areas that Donald E. Todd examines in his Environmental chemistry study include Soil contamination and Terrestrial ecosystem.
His studies deal with areas such as Carbon dioxide and Precipitation as well as Hydrology. His studies examine the connections between Nutrient and genetics, as well as such issues in Animal science, with regards to Soil fertility. His study in Soil carbon is interdisciplinary in nature, drawing from both Soil organic matter, Isotope analysis, Litter and Soil horizon.
The scientist’s investigation covers issues in Soil water, Environmental chemistry, Ecosystem, Vegetation and Potassium. He integrates Soil water and Spatial distribution in his studies. Spatial distribution is integrated with Mercury, Terrestrial ecosystem, Trace element, Soil contamination and Ecology in his study.
In his works, he conducts interdisciplinary research on Mercury and Organic matter. His work carried out in the field of Vegetation brings together such families of science as Soil science, Detritus, Leaching and Deciduous. His Carbon dioxide research incorporates themes from Hydrology, Climate change, Atmospheric sciences and Soil respiration.
