Increasing nitrogen (N) deposition or fertilization has been found to significantly affect carbon (C) cycling. However, a comprehensive understanding of how different C chemical components plant, litter, and soil would respond external N addition is still lacking. We compiled data 1,160 observations from 52 individual studies conducted meta-analysis effects on 18 variables related compositions in terrestrial ecosystems. Results showed that plant lignin (+7.13%), protein (+25.94%), (+7.30%)...
The impact of biochar application on crop yield has always been a topic concern. However, most current research focuses the short-term effects growth. Investigating long-term in increasing yields is crucial for food security and sustainable agricultural development. To address this issue, study performed coupling meta-analysis structural equation model (SEM) based establishment dataset containing 981 sets observations. results demonstrated that significantly durably boosted yield, also shown...
Updating and refining the N2O emission factors (N2O-EFs) are vital to reduce uncertainty in estimates of direct emissions. Based on a database with 1151 field measurements across China, N2O-EFs were established via three approaches including maximum likelihood method, linear regression an intercept set 0 using 70% observations. The remaining 30% observations then used evaluate predicted N2O-EFs. third method had highest R2 0.39 best model efficiency 0.38 no significant bias, showing...
Despite research into the response of ammonia (NH3 ) volatilization in farmland to various meteorological factors, potential impact future climate change on NH3 is not fully understood. Based a database consisting 1063 observations across China, nonlinear models considering crop type, meteorological, soil and management variables were established via four machine learning methods, including support vector machine, multi-layer perceptron, gradient boosting random forest (RF). The RF model had...
Alterations in aboveground plant litter inputs due to global climate change can strongly soil nitrogen (N) cycling, which will influence processes and functions. However, a comprehensive evaluation for the effects of altered on N cycling is not available. We evaluated these using meta-analysis based 1829 observations from 119 studies across different ecosystems including forests, shrublands grasslands. Results showed that addition significantly increased pools total (TN), dissolved organic...
Abstract Biochar soil amendment ( BSA ) had been advocated as a promising approach to mitigate greenhouse gas GHG emissions in agriculture. However, the net mitigation potential of remained unquantified with regard manufacturing process and field application. Carbon footprint CF was employed assess mitigating by estimating all direct indirect full life cycles crop production including application biochar. Data were obtained from 7 sites (4 for paddy rice 3 maize production) under single at...
Abstract The regulation of soil water retention by biochar amendment has been concerned especially in cropland ecosystem. However, the quantification biochar's effects on hydrological properties and crop use efficiency (WUE) is still limited, factors driving effect need to be investigated. Based a database with 681 observations, meta‐analysis structural equation model (SEM) were employed reveal how affects supply capacity WUE. results showed that application increased available content (AWC)...
Nitrogen (N) deposition has increased significantly globally since the industrial revolution. Previous studies on response of gaseous emissions to N have shown controversial results, pointing system-specific effect addition. Here we conducted an addition experiment in a temperate natural forest northeastern China test how potential changes alter soil N2O emission and its sources from nitrification denitrification. Soil was measured using closed chamber method separate incubation acetylene...
Abstract Increasing atmospheric reactive nitrogen (N) deposition due to human activities could change N cycling in terrestrial ecosystems. However, the differences between fates of deposited and are still not fully understood. Here, we investigated , respectively, via application 15 NH 4 NO 3 a temperate forest ecosystem. Results showed that at 410 days after tracer application, most was immobilized litter layer (50 ± 2%), while considerable amount penetrated into 0–5 cm mineral soil (42...
Anthropogenic nitrogen (N) deposition substantially alters N cycling in terrestrial ecosystems because of its effects on soil physicochemical properties and microbes. Responses transformation processes to consecutive additions are unclear, pointing a lack systematic understanding under long-term addition. This work combines 15N tracing laboratory incubation with the FLUAZ model study potential gross N-cycling temperate forest ecosystem eastern Asia after 6 years at rate 50 kg ha−1 year−1....
Paddy rice cultivation is a vital food source but also significant contributor to greenhouse gas (GHG) emissions, particularly methane. Management measures such as improved water management and fertilization are being pursued sustain production while cutting down the emissions. However, climate change may pose further challenges for sustainable agriculture by either impacting or GHG Based on database consisting of 1216 observations across China, we established machine learning models...
SUMMARY There is limited information about the influences of long-term fertilizer management on methane (CH 4 ) and nitrous oxide (N 2 O) emissions from double-cropping paddy fields in Southern China. Therefore, objective present study was to characterize changes CH N O related different treatments based a field experiment. The experiment initiated 1986 consisted five treatments: unfertilized (CK), mineral alone (MF), rice residues plus (RF), low manure rate (M1 + F), high (M2 F)....
