Improving soil C projections is of a high priority for Earth system modeling in the future IPCC and other assessments. To achieve this goal, we suggest that (1) model structures should reflect real\uffe2\uff80\uff90world processes, (2) parameters should be calibrated to match model outputs with observations, and (3) external forcing variables should accurately prescribe the environmental conditions that soils experience. First, most soil C cycle models simulate C input from litter production and C release through decomposition. The latter process has traditionally been represented by first\uffe2\uff80\uff90order decay functions, regulated primarily by temperature, moisture, litter quality, and soil texture. While this formulation well captures macroscopic soil organic C (SOC) dynamics, better understanding is needed of their underlying mechanisms as related to microbial processes, depth\uffe2\uff80\uff90dependent environmental controls, and other processes that strongly affect soil C dynamics. Second, incomplete use of observations in model parameterization is a major cause of bias in soil C projections from ESMs. Optimal parameter calibration with both pool\uffe2\uff80\uff90 and flux\uffe2\uff80\uff90based data sets through data assimilation is among the highest priorities for near\uffe2\uff80\uff90term research to reduce biases among ESMs. Third, external variables are represented inconsistently among ESMs, leading to differences in modeled soil C dynamics. We recommend the implementation of traceability analyses to identify how external variables and model parameterizations influence SOC dynamics in different ESMs. Overall, projections of the terrestrial C sink can be substantially improved when reliable data sets are available to select the most representative model structure, constrain parameters, and prescribe forcing fields.</p>", "keywords": ["550", "LAND MODELS", "Oceanography", "HETEROTROPHIC RESPIRATION", "01 natural sciences", "Atmospheric Sciences", "LITTER DECOMPOSITION", "ORGANIC-CARBON", "Geoinformatics", "GLOBAL CLIMATE-CHANGE", "DATA-ASSIMILATION", "Meteorology & Atmospheric Sciences", "TEMPERATURE SENSITIVITY", "CMIP5", "MICROBIAL MODELS", "0105 earth and related environmental sciences", "2.

However,  how biocrusts change soil organic C decomposition and what factors drive  the effect in response to climate warming remains largely unknown at a  continental scale. 2. We measured microbial respiration and its  temperature sensitivity (Q10) in bare soil lacking biocrusts and two  universal biocrusted soils (cyanobacterial- and moss-crusted soil) from 43  sites across a precipitation gradient from 39 mm to 443 mm to evaluate the  relative effects of biocrusts on Q10 and the driving forces in northern  China\u2019s dryland. 3. Microbial respiration increased and Q10 decreased with  increasing precipitation in bare soil, cyanobacterial- and moss-crusted  soil. Biocrusts positively affected microbial respiration, with a more  substantial magnitude by moss crusts than cyanobacterial crusts. Biocrusts  negatively impacted Q10, and the magnitudes were similar between moss and  cyanobacterial crusts. Most importantly, the relative effects of biocrusts  on microbial respiration and Q10 increased with decreasing precipitation.  4. The positive effects of biocrusts on soil organic C content and  microbial biomass carbon were positively correlated with the level of  increased microbial respiration. Contrastingly, the magnitude of reduced  Q10 was attributed to the biocrusts\u2019 positive effects on soil organic C  quality and adverse effects on the ratio of fungal to bacterial PLFAs (F:  B). 5. Our study provides strong evidence that biocrusts decrease the  temperature sensitivity of microbial respiration in northern China\u2019s  dryland.

The results highlight the importance of local soil conditions and warming-induced changes therein for future climatic impacts on respiration.</p", "keywords": ["0301 basic medicine", "Ecosystem respiration", "tundra", "Time Factors", "ecosystem respiration", "550", "Datasets as Topic", "Global Warming", "climate warming", "Soil", "Soil Microbiology", "0303 health sciences", "CLIMATE-CHANGE", "Arctic Regions", "Temperature", "Hydrogen-Ion Concentration", "Plants", "Settore BIOS-01/C - Botanica ambientale e applicata", "Multidisciplinary Sciences", "Biologie et autres sciences connexes", "climate change", "Science & Technology - Other Topics", "Seasons", "Warming", "DECOMPOSITION", "570", "Climatologie et m\u00e9t\u00e9orologie", "General Science & Technology", "Nitrogen", "Cell Respiration", "Article", "Carbon Cycle", "03 medical and health sciences", "TEMPERATURE SENSITIVITY", "CYCLE", "Tundra", "METAANALYSIS", "Ecosystem", "Science & Technology", "organic carbon", "COMPONENTS", "15.

It quantifies the effect of change from annual to perennial crops and the subsequent temporal changes in SOC stocks during the perennial crop cycle. It also presents an empirical model to estimate changes in the SOC content under crops as a function of time, land use, and site characteristics. We used a harmonized global dataset containing paired\uffe2\uff80\uff90comparison empirical values of SOC and different types of perennial crops (perennial grasses, palms, and woody plants) with different end uses: bioenergy, food, other bio\uffe2\uff80\uff90products, and short rotation coppice. Salient outcomes include: a 20\uffe2\uff80\uff90year period encompassing a change from annual to perennial crops led to an average 20% increase in SOC at 0\uffe2\uff80\uff9330\uffc2\uffa0cm (6.0\uffc2\uffa0\uffc2\uffb1\uffc2\uffa04.6\uffc2\uffa0Mg/ha gain) and a total 10% increase over the 0\uffe2\uff80\uff93100\uffc2\uffa0cm soil profile (5.7\uffc2\uffa0\uffc2\uffb1\uffc2\uffa010.9\uffc2\uffa0Mg/ha). A change from natural pasture to perennial crop decreased SOC stocks by 1% over 0\uffe2\uff80\uff9330\uffc2\uffa0cm (\uffe2\uff88\uff922.5\uffc2\uffa0\uffc2\uffb1\uffc2\uffa04.2\uffc2\uffa0Mg/ha) and 10% over 0\uffe2\uff80\uff93100\uffc2\uffa0cm (\uffe2\uff88\uff9213.6\uffc2\uffa0\uffc2\uffb1\uffc2\uffa08.9\uffc2\uffa0Mg/ha). The effect of a land use change from forest to perennial crops did not show significant impacts, probably due to the limited number of plots; but the data indicated that while a 2% increase in SOC was observed at 0\uffe2\uff80\uff9330\uffc2\uffa0cm (16.81\uffc2\uffa0\uffc2\uffb1\uffc2\uffa055.1\uffc2\uffa0Mg/ha), a decrease in 24% was observed at 30\uffe2\uff80\uff93100\uffc2\uffa0cm (\uffe2\uff88\uff9240.1\uffc2\uffa0\uffc2\uffb1\uffc2\uffa016.8\uffc2\uffa0Mg/ha). Perennial crops generally accumulate SOC through time, especially woody crops; and temperature was the main driver explaining differences in SOC dynamics, followed by crop age, soil bulk density, clay content, and depth. We present empirical evidence showing that the FAO perennialization strategy is reasonable, underscoring the role of perennial crops as a useful component of climate change mitigation strategies.</p", "keywords": ["MISCANTHUS", "QH301 Biology", "Carbon Dynamics in Peatland Ecosystems", "SEQUESTRATION", "01 natural sciences", "630", "BIOMASS", "862695", "Agricultural and Biological Sciences", "Soil", "NE/M021327/1", "woody crops", "Soil water", "SDG 13 - Climate Action", "Development and Impacts of Bioenergy Crops", "STOCKS", "NE/N017854/1", "SDG 15 - Life on Land", "General Environmental Science", "agriculture", "2.

Geothermally active areas in Iceland provided wide, continuous and stable gradients of\u00a0soil temperatures\u00a0to test this hypothesis. In order to characterize the stoichiometric demands of microbes from these subarctic soils, we incubated soils from ambient temperatures after the factorial addition of C, N and P substrates separately and in combination. In a second experiment, soils that had been exposed to different\u00a0in situ\u00a0warming intensities (+0, +0.5, +1.8, +3.4, +8.7, +15.9\u00a0\u00b0C above ambient) for seven years were incubated after the combined addition of C, N and P to evaluate the capacity of soil microbes to store and immobilize C and N at the different warming scenarios. The seven years of chronic soil warming triggered large and proportional soil C and N losses (4.1\u00a0\u00b1\u00a00.5% \u00b0C\u22121\u00a0of the stocks in unwarmed soils) from the upper 10\u202fcm of soil, with a predominant depletion of the physically accessible organic substrates that were weakly sorbed in\u00a0soil minerals\u00a0up to 8.7\u202f\u00b0C warming. Soil microbes met the increasing respiratory demands under conditions of low C accessibility at the expenses of a reduction of the standing biomass in warmer soils. This together with the strict microbial C:N stoichiometric demands also constrained their capacity of N retention, and increased the vulnerability of soil to N losses. Our findings suggest a strong control of\u00a0microbial physiology and C:N stoichiometric needs on the retention of soil N and on the resilience of soil C stocks from high-latitudes to warming, particularly during periods of vegetation dormancy and low C inputs.", "keywords": ["0301 basic medicine", "Microbial carbon and nutrients limitation", "Microbial biomass", "TERM", "03 medical and health sciences", "FOREST SOIL", "Temperature increase", "ORGANIC-CARBON", "Substrate induced respiration", "SDG 13 - Climate Action", "TEMPERATURE SENSITIVITY", "CYCLE", "106026 Ecosystem research", "METAANALYSIS", "2.
