Soil carbon transformation and sequestration have received significant interest in recent years due to a growing need for quantitating its role mitigating climate change. Even though our understanding of the nature soil organic matter has recently been substantially revised, fundamental uncertainty remains about quantitative importance microbial necromass as part persistent matter. Addressing this hampered by absence assessments whether makes up majority soil. Direct quantitation is very...
Abstract All soils harbor microaggregates, i.e ., compound soil structures smaller than 250 µm. These microaggregates are composed of diverse mineral, organic and biotic materials that bound together during pedogenesis by various physical, chemical biological processes. Consequently, can withstand strong mechanical physicochemical stresses survive slaking in water, allowing them to persist for several decades. Together with the physiochemical heterogeneity their surfaces, three‐dimensional...
Black carbon (BC), the product of incomplete combustion fossil fuels and biomass (called elemental (EC) in atmospheric sciences), was quantified 12 different materials by 17 laboratories from disciplines, using seven methods. The were divided into three classes: (1) potentially interfering materials, (2) laboratory‐produced BC‐rich (3) BC‐containing environmental matrices (from soil, water, sediment, atmosphere). This is first comprehensive intercomparison this type (multimethod, multilab,...
Core Ideas A community effort is needed to move soil modeling forward. Establishing an international consortium key in this respect. There a need better integrate existing knowledge models. Integration of data and models challenge modeling. The remarkable complexity its importance wide range ecosystem services presents major challenges the processes. Although progress has occurred last decades, processes remain disjointed between disciplines or services, with considerable uncertainty...
Summary The great stability of black carbon (BC) in soils may not be solely attributable to its refractory structure but also poor accessibility when physically enveloped by soil particles. Our aim was elucidate the intensity physical entrapment BC within aggregates. For this purpose, A horizon a forest, and grassland soil, three under tillage, were sampled at experimental station Rotthalmünster, Germany. Black assessed water‐stable aggregates aggregate‐density fractions using benzene...
Recently, it has been suggested that soil organic C (SOC) does not always respond linearly to increasing input, thereby limiting the rate and efficiency of stabilization in soils. Therefore, we postulated when a is exposed broad range inputs through manure treatments, will show saturation behavior different SOC pools saturate at rates. To test this, were isolated by physical fractionation techniques from long‐term agricultural experiment Lethbridge, Canada. In this experiment, applied since...
Summary Crucial steps in geochemical cycles are many cases performed by more than one group of microorganisms, but the significance this functional redundancy with respect to ecosystem functioning is poorly understood. Ammonia‐oxidizing archaea (AOA) and their bacterial counterparts (AOB) a perfect system address question: although performing same transformation step, they belong well‐separated phylogenetic groups. Using pig manure amended different concentrations sulfadiazine (SDZ), an...
Abstract The temperature sensitivity of heterotrophic soil respiration is crucial for modeling carbon dynamics but it variable. Presently, however, most models employ a fixed value 1.5 or 2.0 the increase per 10°C in (Q10). Here we identified variability Q10 at regional scale (Rur catchment, Germany/Belgium/Netherlands). We divided study catchment into environmental classes (ESCs), which define as unique combinations land use, aggregated groups, and texture. took nine samples from each ESC...
Phosphorus availability may shape plant–microorganism–soil interactions in forest ecosystems. Our aim was to quantify the between soil P and nutrition strategies of European beech (Fagus sylvatica) forests. We assumed that plants microorganisms P-rich forests carry over mineral-bound into biogeochemical cycle (acquiring strategy). In contrast, P-poor ecosystems establish tight cycles sustain their demand (recycling tested if this conceptual model on supply-controlled consistent with data...
