1Nutrient availability and leaching in an archaeological Anthrosol and a Ferralsol of the Central Amazon basin: fertilizer, manure and charcoal amendments显示文摘Johannes Lehmann Jose Pereira da Silva Christoph Steiner Thomas Nehls Wolfgang Zech Bruno Glaser 2003Plant and Soil2003,,2:8
2Community assemblage of free-living diazotrophs along the elevational gradient of Mount Gongga显示文摘Mountain systems are unique for studying the responses of species distribution and diversity to environmental changes along elevational gradients.It is well known that free-living diazotrophic microorganisms are important to nitrogen cycling in mountain systems.However,the elevational patterns of free-living diazotrophs and the underlying ecological processes in controlling their turnover along broader gradients are less well documented.Here,we investigated the pattern of diazotrophic diversity along the elevational gradient(1800 m-4100 m)in Mount Gongga of China.The results showed that the α-diversity of diazotrophs did not change with the elevation from 1800 m to 2800 m,but decreased at elevations above 3000 m.Such diversity pattern was driven mainly by soil total carbon,nitrogen,and plant richness.Various diazotrophic taxa showed differential abundance-elevation relationships.Ecological processes determining diazotrophic community assemblage shift along the elevations.Deterministic processes were relatively stronger at both low and high elevations,whereas stochastic processes were stronger at the middle elevation.This study also suggested a strong relationship among aboveground plants and diazotrophs,highlighting their potential interactions,even for free-living diazotrophs.Yansu Wang Chaonan Li Zehao Shen Junpeng Rui Decai Jin Jiabao Li Xiangzhen Li 2019Soil Ecology Letters2019,1,3:8
3Soil microbial carbon pump:Mechanism and appraisal显示文摘The soil microbial carbon pump(MCP)conceptualizes a sequestration mechanism based on the process of microbial production of a set of new organic compounds,which carry the carbon from plant,through microbial anabolism,and enter into soil where it can be stabilized by the entombing effect.Understanding soil MCP and its related entombing effect is essential to the stewardship of ecosystem services,provided by microbial necromass in the formation and stabilization of soil organic matter as well as its resilience and vulnerability to global change.The mechanism and appraisal of soil MCP,however,remain to be elucidated.This lack of knowledge hampers the improvement of climate models and the development of land use policies.Here,I overview available knowledge to provide insights on the nature of the soil MCP in the context of two main aspects,i.e.,internal features and external constraints that mechanistically influence the soil MCP operation and ultimately influence microbial necromass dynamics.The approach of biomarker amino sugars for investigation of microbial necromass and the methodological limitations are discussed.Finally,I am eager to call new investigations to obtain empirical data in soil microbial necromass research area,which urgently awaits synthesized quantitative and modeling studies to relate to soil carbon cycling and climate change.Chao Liang 2020Soil Ecology Letters2020,2,4:8
4Dynamic changes in soil chemical properties and microbial community structure in response to different nitrogen fertilizers in an acidified celery soil显示文摘To determine the effects of different kinds of nitrogen fertilizer,especially high-efficiency slowrelease fertilizers,on soil pH,nitrogen(N)and microbial community structures in an acidic celery soil,four treatments(CK,no N fertilizer;NR,urea;PE,calcium cyanamide fertilizer;and SK,controlled-release N fertilizer)were applied,and soil pH,total soil N,inorganic N,and soil microbial biomass C were analyzed.Phospholipid fatty acids(PLFAs)were extracted and detected using the MIDI Sherlock microbial identification system.The PE treatment significantly improved soil pH,from 4.80 to>6.00,during the whole growth period of the celery,and resulted in the highest celery yield among the four treatments.After 14 d application of calcium cyanamide,the soil nitrate content significantly decreased,but the ammonium content significantly increased.The PE treatment also significantly increased soil microbial biomass C during the whole celery growth period.Canonical variate analysis of the PLFA data indicated that the soil microbial community structure in the CK treatment was significantly different from those in the N applied treatments after 49 d fertilization.However,there was a significant difference(P<0.05)in soil microbial community structure between the PE treatment and the other three treatments at the end of the experiment.Calcium cyanamide is a good choice for farmers to use on acidic celery land because it supplies sufficient N,and increases soil pH,microbial biomass and the yield of celery.Yuping Wu Jiangxing Wu Yongjun Ma Ying Lian Hui Sun Danchao Xie Yaying Li Philip C.Brookes Huaiying Yao 2019Soil Ecology Letters2019,1,3:7
5Seasonal changes of soil erosion and its spatial distribution on a long gentle hillslope in the Chinese Mollisol region显示文摘Understanding seasonal soil erosion and deposition rates and their spatial distribution along sloping farmlands are necessary for erosion prediction technology and implementing effective soil conservation practices.To date seasonal change of soil erosion and soil redistribution on long gentle hillsiopes are not fully quantified due to the variable erosive forces in different seasons.A multi-tracer method using rare earth elements(REE)was employed to discriminate seasonal changes of soil erosion and its spatial distribution on a sloping farmland driven by snowmelt runoff,wind force and rainfall-runoff.A long-slope runoff plot with 5 m wide and 320 m long located in the typical Mollisol region of China was divided into eight segments,each of which was 40 m long and tagged with one of eight REE oxides.The spot method of a partial-area tagging scheme was employed and a grid-based layout was used for REE application.Results showed that annual soil erosion rate was 3251.01 km^(-2)for the whole runoff plot,in which snowmelt runoff erosion contributed 537.3 t km^(-2),wind erosion 363.11 km-2 and rainfall-runoff erosion 2350.6 t km^(-2).Surface runoff is the main external erosive force of hillslope soil erosion,accounting for 88.8%of the total annual soil loss.Furthermore,for the eight slope segments of the 320-m long hillslope,the sediment transport ratios of each slope segment caused by snowmelt runoff and rainfall-runoff erosion were more than 23.5%and 34.7%,respectively.The results will enrich the understanding of seasonal soil erosion on long hillsiopes.Lei Wang Fenli Zheng Gang Liu Xunchang J.Zhang Glenn V.Wilson Hongqiang Shi Xujun Liu 2021International Soil and Water Conservation Research2021,9,3:6
6High manure load reduces bacterial diversity and network complexity in a paddy soil under crop rotations显示文摘Long-term application of chemical fertilizers causes soil degradation and nitrogen(N)loss,but these effects could be alleviated by organic fertilizers.In addition,crop rotation is a feasible practice to increase soil fertility,soil quality and crop yields comparing with monocultural cropping patterns.However,questions remain concerning how the soil microbiome responds to different manure application rates under crop rotations.Here,we collected soil samples from a rice-rape system to investigate the response of the soil microbiome to nine years of pig manure application at different rates(CK:0 kg ha^(-1),M1:1930 kg ha^(-1),M2:3860 kg ha^(-1) and M3:5790 kg ha^(-1)).Our results revealed that the bacterialα-diversity(Chao1 and Shannon index)in the rape season increased first and then decreased with increasing manure application rates,and a high manure load tended to decrease the bacterialα-diversity in the rice season.Long-term manure application enriched some copiotrophic bacteria,such as Proteobacteria and Actinobacteria,while it decreased the relative abundance of Nitrospirae.Redundancy analysis(RDA)and the Mantel test indicated that soil pH,TC,TN,AP,C/P and N/P ratios were the main factors influencing bacterial communities.Moreover,network analysis showed that a low manure application rate shaped a complexly connected and stable bacterial community,while higher manure application rate decreased the stability of the bacterial network.These findings improve our understanding of bacterial responses to longterm manure application under crop rotations and their relationships with soil factors,especially in the context of increasing fertilizer inputs.Haiyang Liu Xing Huang Wenfeng Tan Hongjie Di Jianming Xu Yong Li 2020Soil Ecology Letters2020,2,2:6

8Assessing soil thickness in a black soil watershed in northeast China using random forest and field observations显示文摘Soil thickness determines the soil productivity in the black soil region of northeast China,which is important for national food security.Existing information on the spatial variation of black soil thickness is inadequate.In this paper,we propose a model framework for spatial estimation of the black soil thickness at the watershed scale by integrating field observations,unmanned aerial vehicle variations of topography,and satellite variations of vegetation with the aid of random forest.We sampled 141 sample profiles over a watershed and identified the black soil thickness based on indices of the mollic epipedon.Topographic variables were derived from a digital elevation model and vegetation variables were derived from Landsat 8 imagery.Random forest was used to determine the relationship between black soil thickness and environmental variables.The resulting model explained 61%of the black soil thickness spatial variation,which was more than twice that of traditional interpolation methods(ordinary kriging,universal kriging and inverse distance weighting).Topographic variables contributed the most toward explaining the thickness,followed by vegetation indices.The black soil thickness over the watershed had a clear catenary soil pattern,with thickest black soil in the low depositional areas and thinnest at the higher elevations that drain into the low areas.The proposed model framework will improve estimates of soil thickness in the region of our study.Shuai Zhang Gang Liu Shuli Chen Craig Rasmussen Baoyuan Liu 2021International Soil and Water Conservation Research2021,9,1:5

10Soil fungal community is more sensitive to nitrogen deposition than increased rainfall in a mixed deciduous forest of China显示文摘Nitrogen(N)deposition and intensified rainfall can strongly affect soil microbial community,but compared with available studies on bacteria,those on soil fungi are quite limited.Here we carried out a field experiment in a mixed deciduous forest of China to study the influences of increased N deposition and rainfall on soil fungi by using quantitative PCR and high-throughput sequencing method.The results demonstrated that(1)N addition significantly increased fungal abundance and alpha diversity(richness,Shannon index and Invsimpson index),changed fungal community composition at OTU level,and marginally increased the relative abundance of Ascomycota and Zygomycota,while water addition showed no remarkable effects on fungal abundance,biodiversity and community composition.(2)N addition significantly increased the richness of saprotrophic fungi and pathogenic fungi,and the relative abundance of saprotrophic fungi,but water addition only slightly increased the abundance of pathogenic fungi.(3)Fungal composition dissimilarity closely correlated with the disparity of soil parameters as a whole.Soil NH_(4)^(+)-N exhibited strong positive correlation with the richness of pathogenic fungi and mycorrhizal fungi,while both soil moisture and NH_(4)^(+)-N tightly correlated with soil fungal abundance and alpha diversity indices.We concluded that in this N-limited but non-water-limited forest ecosystem,N deposition posed stronger effects on soil fungi than increased rainfall,partially mediated by changes in soil properties.Aihua Zhao Lei Liu Baodong Chen Wei Fu Wei Xie Tianle Xu Wei Zhang Qing Ye Haiyan Feng Shenglei Fu 2020Soil Ecology Letters2020,2,1:5
11The soil configuration on granite residuals affects Benggang erosion by altering the soil water regime on the slope显示文摘A permanent collapsing gully,locally called Benggang,formed on slopes with deep granite red soil and is a type of unique gully erosion widely prevalent in southern China.Three different soil configurations(SC),ie,red-transition-sandy(SC I,the transition is the soil layer between the red soil and the sandy soil layer),transition-sandy(SC II)or sandy(SC III)are usually present in the soil profile of the Benggang slope.However,little attention has been paid to impacts of SCs on the triggering of Benggang erosion.In this study,we aimed to explore the relationships between soil water content(SWC)and triggering of Benggang erosion under different SC conditions.The soil properties of different soil layers were measured and the SWC at depths of 20,40,60,and 80 cm were monitored at 5-min intervals along a typical Benggang(SC I)during 2016-2018.The SWC of Benggang slopes with different SCs were simulated by VADOSE/W model.Results showed that the red soil layer had a higher water retention capacity and shear strength than the sandy soil layer.Even if the SWC is higher(e.g.,0.42 cm^(3)/cm^(3))at red soil layer or transition layer,the corresponding shear strength is greater than that of sandy soil layer with a lower SWC(e.g.,032 cm^(3)/cm^(3)).Relationships between shear strength and SWC of different soil layers indicate that Benggang erosion is triggered by an increase in the SWC in the deep sandy layer.Results also showed that differences exist in the SWC distribution among the different SCs.The SWC is higher in topsoil than in deeper soil in SC I and SC II,while in SC III,the opposite trend is observed.These results revealed that the presence of the red soil or transition layer can reduce the infiltration of rainwater into the deep sandy layer,thus can reduce the possibility of collapse.Our results show that the SC affects the stability of the headwall,and results provide great significances to guide the mitigation of Benggang erosion.Xiaoqian Duan Yusong Deng Yu Tao Yangbo He Lirong Lin Jiazhou Chen 2021International Soil and Water Conservation Research2021,9,3:4
12Soil erosion assessment by RUSLE with improved P factor and its validation:Case study on mountainous and hilly areas of Hubei Province,China显示文摘The Revised Universal Soil Loss Equation(RUSLE)is widely used to estimate regional soil erosion.However,quantitative impacts of soil and water conservation(SWC)measures on conservation practice factor(P)of the RUSLE remain largely unclear,especially for the mountainous and hilly areas.In this study,we improved the RUSLE by considering quantitative impacts of different SWC measures on the P factor value.The improved RUSLE was validated against the long-term(2000-2015)soil erosion monitoring data obtained from 96 runoff plots(15—35°)in mountainous and hilly areas of Hubei Province,China;the result presented a high accuracy with the determination coefficient of 0.89.Based on the erosion monitoring data of 2018 and 2019,the Root Mean Square Error of the result by the improved RUSLE was 28.0%smaller than that by the original RUSLE with decrement of 19.6%—24.0%in the average P factor values,indicating that the soil erosion modelling accuracy was significantly enhanced by the improved RUSLE.Relatively low P factor values appeared for farmlands with tillage measures(P<0.53),grasslands with engineering measures(P<0.23),woodlands with biological measures(P<0.28),and other land use types with biological measures(P<0.51).The soil erosion modulus showed a downward trend with the corresponding values of 1681.21,1673.14,1594.70,1482.40 and 1437.50 t km^(-2)a-1 in 2000,2005,2010,2015 and 2019,respectively.The applicability of the improved RUSLE was verified by the measurements in typical mountainous and hilly areas of Hubei Province,China,and arrangements of SWC measures of this area were proposed.Pei Tian Zhanliang Zhu Qimeng Yue Yi He Zhaoyi Zhang Fanghua Hao Wenzhao Guo Lin Chen Muxing Liu 2021International Soil and Water Conservation Research2021,9,3:4
13Soil biofilms:microbial interactions,challenges,and advanced techniques for ex-situ characterization显示文摘Soil is inhabited by a myriad of microorganisms,many of which can form supracellular structures,called biofilms,comprised of surface-associated microbial cells embedded in hydrated extracellular polymeric substance that facilitates adhesion and survival.Biofilms enable intensive inter-and intra-species interactions that can increase the degradation efficiency of soil organic matter and materials commonly regarded as toxins.Here,we first discuss organization,dynamics and properties of soil biofilms in the context of traditional approaches to probe the soil microbiome.Social interactions among bacteria,such as cooperation and competition,are discussed.We also summarize different biofilm cultivation devices in combination with optics and fluorescence microscopes as well as sequencing techniques for the study of soil biofilms.Microfluidic platforms,which can be applied to mimic the complex soil environment and study microbial behaviors at the microscale with highthroughput screening and novel measurements,are also highlighted.This review aims to highlight soil biofilm research in order to expand the current limited knowledge about soil microbiomes which until now has mostly ignored biofilms as a dominant growth form.Peng Cai Xiaojie Sun Yichao Wu Chunhui Gao Monika Mortimer Patricia A.Holden Marc Redmile-Gordon Qiaoyun Huang 2019Soil Ecology Letters2019,1,3:4
14Loss of soil microbial diversity exacerbates spread of antibiotic resistance显示文摘Loss of biodiversity is a major threat to the ecosystem processes upon which society depends.Natural ecosystems differ in their resistance to invasion by alien species,and this resistance can depend on the diversity in the system.Little is known,however,about the barriers that microbial diversity provides against microbial invasion.The increasing prevalence of antibioticresistant bacteria is a serious threat to public health in the 21st century.We explored the consequences of the reduction in soil microbial diversity for the dissemination of antibiotic resistance.The relationship between this diversity and the invasion of antibiotic resistance was investigated using a dilution-to-extinction approach coupled with high-capacity quantitative PCR.Microbial diversity was negatively correlated with the abundance of antibiotic-resistance genes,and this correlation was maintained after accounting for other potential drivers such as incubation time and microbial abundance.Our results demonstrate that high microbial diversity can act as a biological barrier resist the spread of antibiotic resistance.These results fill a critical gap in our understanding of the role of soil microbial diversity in the health of ecosystems.Qing-Lin Chen Xin-Li An Bang-Xiao Zheng Michael Gillings Josep Penuelas Li Cui Jian-Qiang Su Yong-Guan Zhu 2019Soil Ecology Letters2019,1,1:4
15Acid leaching of heavy metals from contaminated soil collected from Jeddah,Saudi Arabia:kinetic and thermodynamics studies显示文摘Urban soils polluted with heavy metals are of increasing concern because it is greatly affecting human health and the ecological systems.Hence,it is mandatory to understand the reasons behind this pollution and remediate the contaminated solid.The removal of heavy metals from contaminated soil samples collected from the vicinity of the sewage lake in Jeddah,Saudi Arabia,was explored.The leaching process was studied kinetically and thermodynamically for better understanding of the remediation process.The results showed that the soil samples were slightly basic in nature,and tend to be more neutral away from the main contaminated sewage lake area.The total metal content in the soil samples was measured using the aqua regia extractions by ICPOES and the results showed that many of the heavy metals present have significant concentrations above the tolerable limits.In general,the metal concentrations at different sites indicated that the heavy metal pollution is mainly due to the sewage discharge to the lake.The results showed excellent correlation between the concentrations of Co,As,and Hg with the distance from the main contaminated area.The leaching of Co,As,and Hg using 1.0 M hydrochloric acid from the soil was studied kinetically at different temperatures and the experimental results were fitted using different kinetics models.The experimental data were best described with two-constant rate and Elovich equation kinetic models.Also,the thermodynamic study showed that the leaching process was spontaneous,endothermic and accompanied with increase in the entropy.In general,the polluted soil could be remediated successfully from the heavy metals using the acid leaching procedure in a short period of time.Shorouq I.Alghanmi Amani F.Al Sulami Tahani A.El-Zayat Basma G.Alhogbi Mohamed Abdel Salam 2015International Soil and Water Conservation Research2015,3,3:4

19Duration and intensity of rainfall events with the same erosivity change sediment yield and runoff rates显示文摘The effect of different rainfall patterns on surface runoff,infiltration and thus soil losses and sediment concentrations are still in the focus of current research.In most simulated rainfall experiments,pre-cipitation is applied at a fixed intensity for a fixed time.However,the impact of rainfall patterns on soil erosion processes may be different varying the rainfall duration and intensity that produces an event with similar rainfall erosivity values.Twenty-five rainfall events were applied on micro-scale runoff plots in a soil covered with corn straw to evaluate the sediment yield and runoff rates.The different rainfall types were composed by association of duration(Dur)and intensity(IP)with the same erosivity value.The Dur varied from 38 to 106 min and the IP varied from 75.0 to 44.6 mm h^(-1).The sediment yield varied from 1.89±1.26 g m^(-2) to 4.02±2.66 g m^(-2) and runoff ranged from 16.9±8.74 mm to 32.63±10.67 mm with highest rates occurring with high intensity and low duration.The highest rainfall intensity provides the maximum sediment yield(0.138 g m^(-2) min^(-1))and runoff rates(0.87 mm min^(-1)).The time to start surface runoff varied from 14 to 19.2 min and it was longer in treatments with longer durations and low precipitation intensity.No difference was found in the amount of sediments applying rain with the same erosivity and different associations of duration and intensity.However,the intensity and duration of the rain,with the same erosivity,altered the amount and time of runoff.In rainfall experiments with con-stant intensity and fixed time,the erosion rates depend on the duration of the applied rain.Therefore,the results of this study can contribute to the development of new perspectives in the design of water erosion experiments with simulated rain considering the duration,intensity and also the association of these variables to produce rainfall that delivery the same soil erosion capacity.Wilk Sampaio de Almeida Steffen Seitz Luiz Fernando Coutinho de Oliveira Daniel Fonseca de Carvalho 2021International Soil and Water Conservation Research2021,9,1:4
