Soil Biogeochemistry of Nitrogen, Phosphorus, and Carbon Cycles
This community investigates the transformation, removal, and recovery of nitrogen, phosphorus, and carbon within soil and aquatic systems to manage agricultural productivity and water quality.
The research focuses on the biogeochemical cycling of nutrients, specifically the mechanisms of nitrogen fixation, denitrification, and phosphorus availability in soils. A significant portion of the work addresses the removal of excess nitrogen and phosphorus from wastewater and sewage sludge to prevent eutrophication, utilizing methods such as constructed wetlands and microbial community manipulation. The community also examines the role of soil organic matter and microbial communities in carbon sequestration and greenhouse gas emissions, including nitrous oxide and carbon dioxide. Key materials and processes include biochar application, phosphate adsorption, and the interaction between fertilizer use efficiency and soil health.
The largest share of the community's output is found in phosphorus research, accounting for 30.1% of all phosphorus research, and 32,000 papers here. Nitrogen research contributes 18.2% of its element-specific output, with 25,670 papers.
The community comprises 104,995 papers, published primarily in Water Research, Bioresource Technology, and the Journal of Water Process Engineering.
Recent work continues to focus on optimizing nutrient removal technologies, such as anammox processes and constructed wetlands, while also exploring the impact of long-term fertilization on soil carbon storage and the role of microbial communities in denitrification pathways.
