His main research concerns Agronomy, Lolium perenne, Trifolium repens, Nitrogen fixation and Ecosystem. His Lolium perenne research includes themes of Monoculture, Soil water, Soil fertility and Repens. His Trifolium repens research is classified as research in Botany.
The Terrestrial ecosystem research Ueli A. Hartwig does as part of his general Ecosystem study is frequently linked to other disciplines of science, such as Carbon sequestration, therefore creating a link between diverse domains of science. His Terrestrial ecosystem research is multidisciplinary, incorporating elements of Soil organic matter, Primary production and Biomass. His work carried out in the field of Perennial plant brings together such families of science as Nutrient, Nitrogen cycle, Carbon sink and Rhizobium leguminosarum.
Ueli A. Hartwig spends much of his time researching Agronomy, Trifolium repens, Lolium perenne, Nitrogen fixation and Botany. Ueli A. Hartwig has included themes like Nutrient, Ecosystem, Soil fertility and Horticulture in his Agronomy study. Ueli A. Hartwig has researched Ecosystem in several fields, including Biomass and Temperate climate.
His research integrates issues of Soil biology, Soil carbon, Soil water and Repens in his study of Trifolium repens. His biological study spans a wide range of topics, including Monoculture, Carbon dioxide, Human fertilization and Nitrate. His Botany research is multidisciplinary, relying on both Molecular biology, Nitrogenase, Nitrogen cycle and Rhizobia.
Agronomy, Lolium perenne, Trifolium repens, Soil water and Ecology are his primary areas of study. His Agronomy research incorporates elements of Arbuscular mycorrhiza and Biodiversity. His Lolium perenne research is multidisciplinary, incorporating perspectives in Denitrification and Carbon dioxide.
His Trifolium repens research incorporates themes from Monoculture and Nitrogen cycle. Ueli A. Hartwig works mostly in the field of Soil water, limiting it down to concerns involving Nitrogen fixation and, occasionally, Soil processes, Soil fertility and Botany. His Grassland, Ecosystem, Plant ecology and Species richness study in the realm of Ecology connects with subjects such as Altitude.
Ueli A. Hartwig focuses on Carbon dioxide, Lolium perenne, Ecosystem, Soil organic matter and pCO2. His Carbon dioxide study combines topics in areas such as Biomass and Perennial plant, Fertilizer, Agronomy. His study in the fields of Terrestrial ecosystem and Primary production under the domain of Ecosystem overlaps with other disciplines such as Carbon sequestration.
His study with Soil organic matter involves better knowledge in Ecology. His pCO2 research incorporates Denitrification, Environmental chemistry, Nitrous oxide, Botany and Nitrification.
