His primary areas of investigation include Ecology, Ecosystem, Soil carbon, Carbon cycle and Nitrogen cycle. His work in Ecology addresses subjects such as Environmental chemistry, which are connected to disciplines such as Soil organic matter and Soil water. His Ecosystem research includes themes of Human impact on the nitrogen cycle, Ecology, Temperate climate and Biogeochemistry.
Alan R. Townsend interconnects Organic matter, Wet season, Tropical climate, Carbon sink and Carbon dioxide in the investigation of issues within Soil carbon. His Carbon cycle research is multidisciplinary, relying on both Spatial distribution and Terrestrial ecosystem. His biological study spans a wide range of topics, including Reactive nitrogen, Primary production and Nitrogen fixation.
Alan R. Townsend mostly deals with Ecology, Ecosystem, Soil water, Nutrient and Nitrogen cycle. His Ecosystem research focuses on Plant litter in particular. His research investigates the connection with Soil water and areas like Environmental chemistry which intersect with concerns in Soil chemistry.
His work focuses on many connections between Nutrient and other disciplines, such as Agronomy, that overlap with his field of interest in Nitrogen fixation, Oxisol, Wet season and Soil fertility. His work in Nitrogen cycle tackles topics such as Reactive nitrogen which are related to areas like Human impact on the nitrogen cycle. Alan R. Townsend combines subjects such as Soil organic matter, Organic matter, Carbon dioxide and Soil respiration with his study of Soil carbon.
Alan R. Townsend mainly focuses on Ecology, Ecosystem, Biodiversity, Biogeochemistry and Nutrient. His study in Ecosystem is interdisciplinary in nature, drawing from both Ecological succession, Nitrogen cycle and Litter. His Nitrogen cycle research integrates issues from Cycling, Nitrification, Tropical rainforest and Ecosystem model.
His research integrates issues of Agroforestry, Resource and Agriculture, Agricultural productivity, Food security in his study of Biodiversity. Alan R. Townsend works mostly in the field of Nutrient, limiting it down to topics relating to Agronomy and, in certain cases, Nitrogen fixation and Biogeochemical cycle, as a part of the same area of interest. His Plant litter research focuses on Organic matter and how it connects with Mineralization, Water content and Soil organic matter.
Alan R. Townsend mainly investigates Ecology, Ecosystem, Nitrogen cycle, Tropics and Niche. His research brings together the fields of Agronomy and Ecology. In his study, which falls under the umbrella issue of Ecosystem, Fossil fuel combustion is strongly linked to Biogeochemistry.
The various areas that Alan R. Townsend examines in his Nitrogen cycle study include Nitrification and Tropical rainforest. The study incorporates disciplines such as Biodiversity, Community structure, Community composition and Disturbance in addition to Niche. His Nutrient cycle research is multidisciplinary, incorporating perspectives in Soil water, Cycling, Species richness, δ15N and Carbon dioxide.
