Identification and quantification of different chemical forms and binding environments of metals in environmental samples

Soil microorganisms that consume nitrogen when carbon is added, affecting plant nutrient availability

Framework suggesting that more labile plant material may be easier for soil microbes to assimilate and transform into microbial necromass, which can become more physically or chemically protected thro...

Associations between organic compounds and reactive minerals that can effectively protect organic compounds from microbial access and represent an important C storage mechanism in upland soil systems

The biological conversion of atmospheric nitrogen to ammonia, making lupine a high-nitrogen host plant

Net uptake rate (NUR) of nitrogen calculated from 15N tracer experiments measuring plant nitrogen acquisition

A measure directly related to the amount of energy required for microbial oxidation of a given compound, with higher NOSC values correlating to lower ΔGox and greater energy yield

Comparison of animal-driven nutrient inputs versus ecosystem uptake capacity to determine if nutrients are in surplus or deficit

Cellular uptake of nutrients by algal colonies from the surrounding water

Determination of ancient water salinity conditions using geochemical and paleontological indicators

Organic matter within the solid phase that can sorb metals and limit their mobility

Surface coatings of Si and organic matter that stabilize ferrihydrite nanoparticles against dissolution or transformation

Capacity of soil to oxidize phenolic compounds, measured using L-DOPA substrate and spectrophotometric detection of oxidation products

Process by which plants convert light energy to chemical energy, with formula 6CO2+6H2O → C6H12O6+6O2

Based on six membered planar hydrocarbon rings, such as benzene, coronene, or anthracene, known carcinogens that play a role in soot formation

Important biochemicals for regular bodily functions, primarily sourced from algae in aquatic systems

Sharp redox gradients that favor the generation of ROS, created by mixing between waters with largely different chemical compositions

Non-majority spatially heterogeneous soil volumes possessing conditions differing from the bulk matrix, where internal oxygen consumption exceeds the rate of oxygen supply

Weathered bedrock zone between soil and unweathered bedrock that retains original rock structure

The dissolution process of iron carbonate mineral (FeCO3) under varying geochemical conditions

The negative feedback system where increased atmospheric CO2 enhances silicate weathering rates, which removes CO2 from the atmosphere through carbonate precipitation
