Soil Nutrient Cycling, Carbon Storage, and Microbial Interactions
This research community investigates how nitrogen, phosphorus, and carbon move through soil systems, how soil microbes and fungi mediate these cycles, and how these processes support crop yield, plant health, and global carbon sequestration.
The work centers on the dynamics of soil organic matter, specifically how nitrogen and phosphorus fertilization, biological fixation, and microbial activity influence nutrient availability and plant growth. Recurring themes include the role of arbuscular mycorrhizal fungi and bacterial communities in enhancing nutrient uptake, the mechanisms of soil carbon sequestration in grasslands and forests, and the impact of land use changes on soil health. The research frequently examines the interplay between abiotic stresses, such as climate change, and biotic factors, like the rhizosphere microbiome, to understand how to sustain agricultural productivity while managing environmental quality and greenhouse gas feedbacks.
The community is most heavily concentrated in phosphorus research, accounting for 10.9% of all tracked phosphorus papers, and nitrogen research, representing 4.3% of that element’s literature. It also contributes 1.8% of carbon research. Phosphorus is the element with both the highest share of this community’s output and the highest paper count within the group.
The community comprises 72,813 papers, with the highest publication volume in Plant and Soil, Soil Science Society of America Journal, and Communications in Soil Science and Plant Analysis.
Recent work continues to focus on the mechanisms of microbial phosphorus cycling, the impact of long-term fertilization on soil carbon storage, and the role of plant growth-promoting bacteria in climate-resilient agriculture.
