| 1 | New approaches for evaluation of soil health, sensitivity and resistance to degradation显示文摘Assessment of soil health requires complexevaluation of properties and functions responsible for abroad range of ecosystem services. Numerous soil qualityindices (SQI) have been suggested for the evaluation ofspecific groups of soil functions, but comparison of variousSQI is impossible because they are based on a combinationof specific soil properties. To avoid this problem, wesuggest an SQI-area approach based on the comparison ofthe areas on a radar diagram of a combination of chemical,biological and physical properties. The new approach isindependent of the SQI principle and allows rapid andsimple comparison of parameter groups and soils. Anotherapproach analyzing the resistance and sensitivity ofproperties to degradation is suggested for a detailedevaluation of soil health. The resistance and sensitivityof soil properties are determined through comparison withthe decrease of soil organic carbon (SOC) as a universalparameter responsible for many functions. The SQI-areaand resistance/sensitivity approaches were tested based on quences after the ab and on ment of agricultural soils. Both the SQI-area and the resistance/sensitivity approaches areuseful for basic and applied research, and for decisionmakersto evaluate land-use practices and measure thedegree of soil degradation. | Yakov KUZYAKOV Anna GUNINA Kazem ZAMANIAN Jing TIAN Yu LUO Xingliang XU Anna YUDINA Humberto APONTE Hattan ALHARBI Lilit OVSEPYAN Irina KURGANOVA Tida GE Thomas GUILLAUME | 2020 | Frontiers of Agricultural Science and Engineering2020，7，3： | 6 |

| 12 | Microplastics affect activity and spatial distribution of C,N, and P hydrolases in rice rhizosphere显示文摘Microplastics provide a new ecological niche for microorganisms,and the accumulation levels of microplastics(MPs)in terrestrial ecosystems are higher than those in marine ecosystems.Here,we applied the zymography to investigate how MPs–polyethylene[PE],and polyvinyl chloride[PVC])at two levels(0.01%and 1%soil weight)impacted the spatial distribution of soil hydrolases,nutrient availability,and rice growth in paddy soil.MPs increased the above-ground biomass by 13.0%–15.5%and decreased the below-ground biomass by 8.0%–15.1%.Addition of 0.01%and 1%MPs reduced soil NH4+content by 18.3%–63.2%and 52.2%–80.2%,respectively.The average activities of N-and P-hydrolases increased by 0.8%–4.8%and 1.9%–6.3%with addition of MPs,respectively.The nutrient uptake by rice plants and the enzyme activities in hotspots increased with MP content in soil.The accumulation of MPs in paddy soil could provide an ecological niche that facilitates microbial survival,alters the spatial distribution of soil hydrolases,and decreases nutrient availability. | Yaoyao Tong Jina Ding Mouliang Xiao Muhammad Shahbaz Zhenke Zhu Ming Chen Yakov Kuzyakov Yangwu Deng Jianping Chen Tida Ge | 2023 | Soil Ecology Letters2023，5，3： | 0 |
| 13 | Distribution of microplastics in soil aggregates after film mulching显示文摘Microplastic distribution is non-homogeneous in agricultural soil following plastic film degradation.However,the distribution of microplastics by shape and particle size in different soil aggregates remains unknown.To elucidate the distribution of microplastic shapes and particle sizes in soil aggregates with increasing years of film mulching,four paired fields with film mulching(FM)and no mulching(NM)were examined at 1,5,10,and 20 years after continuous mulching.An increase in soil aggregates of 0.053–0.25 mm diameter was observed;however,soil organic carbon content decreased after long-term FM.Microplastics primarily combined with 0.053–2 mm soil aggregates.Specifically,long-term FM was associated with dominance of film-and fiber-shaped microplastics in soil aggregates of 0.25–2 mm and 0.053–0.25 mm diameter,respectively.Fiber-and granule-shaped microplastics of 0.25–1 mm diameter primarily combined with 0.053–0.25 and 0.25–2 mm soil aggregates,respectively.Film-shaped microplastics of diameter>1 mm and diameter 0.05–0.25 mm primarily combined with 0.25–2 mm soil aggregates.Therefore,distribution of microplastics in soil aggregates can be used to monitor soil health and quality,greatly enhancing our understanding of the risk posed by microplastics to the environment. | Yuhuai Liu Yingying Zhong Can Hu Mouliang Xiao Fan Ding Yongxiang Yu Huaiying Yao Zhenke Zhu Jianping Chen Tida Ge Jina Ding | 2023 | Soil Ecology Letters2023，5，3： | 0 |
| 14 | Legacy effect of elevated CO_(2) and N fertilization on mineralization and retention of rice (Oryza sativa L.) rhizodeposit-C in paddy soil aggregates显示文摘Rhizodeposits in rice paddy soil are important in global C sequestration and cycling.This study explored the effects of elevated CO_(2) and N fertilization during the rice growing season on the subsequent mineralization and retention of rhizodeposit-C in soil aggregates after harvest.Rice(Oryza sativa L.)was labeled with ^(13)CO_(2) under ambient(400 ppm)and elevated(800 ppm)CO_(2) concentrations with and without N fertilization.After harvest,soil with labeled rhizodeposits was collected,separated into three aggregate size fractions,and flood-incubated for 100 d.The initial rhizodeposit-^(13)C content of N-fertilized microaggregates was less than 65%of that of non-fertilized microaggregates.During the incubation of microaggregates separated from N-fertilized soils,3%–9%and 9%–16%more proportion of rhizodeposit-^(13)C was mineralized to ^(13)CO_(2),and incorporated into the microbial biomass,respectively,while less was allocated to soil organic carbon than in the non-fertilized soils.Elevated CO_(2) increased the rhizodeposit-^(13)C content of all aggregate fractions by 10%–80%,while it reduced cumulative ^(13)CO_(2) emission and the bioavailable C pool size of rhizodeposit-C,especially in N-fertilized soil,except for the silt-clay fraction.It also resulted in up to 23%less rhizodeposit-C incorporated into the microbial biomass of the three soil aggregates,and up to 23%more incorporated into soil organic carbon.These results were relatively weak in the silt-clay fraction.Elevated CO_(2) and N fertilizer applied in rice growing season had a legacy effect on subsequent mineralization and retention of rhizodeposits in paddy soils after harvest,the extent of which varied among the soil aggregates. | Yuhong Li Hongzhao Yuan Anlei Chen Mouliang Xiao Yangwu Deng Rongzhong Ye Zhenke Zhu Kazuyuki Inubushi Jinshui Wu Tida Ge | 2022 | Soil Ecology Letters2022，4，1： | 0 |
| 15 | Effect of N and P fertilization on the allocation and fixation of photosynthesized carbon in paddy soil显示文摘Potted rice seedlings independently treated with N,P,and NP were continuously^(13)CO_(2) labeled to investigated the influence of N and P application on the contribution of photosynthesized C to the rhizosphere versus bulk soil and particulate organic matter(POM)versus mineral fraction(MIN).N and NP enhanced net assimilated^(13)C on day 14(D14),with maximum C assimilation occurring on day 22(D22)under NP.Aboveground biomass retained more^(13)C than belowground biomass for all treatments.^(13)C incorporation into the rhizosphere exceeded that in bulk soil,with the maximum(6-10%)found under N addition.Newly assimilated^(13)incorporated into POM increased in the rhizosphere under N and NP conditions,whereas MIN remained largely unaffected.^(13)C-MBC proportion in the total microbial biomass C(MBC)pool revealed that N and NP stimulated microbial activity to a greater degree than P.The main portion of^(13)C in the rhizosphere and bulk soil was found in POM on D14,which decreased over time due to microbial utilization.Contrastingly,root-derived ^(13)C in the MIN remained unchanged between sampling days,which indicates that the stabilization of rhizodeposits in this fraction might be the potential mechanism underlying SOM sequestration in paddy soils. | Mostafa Zhran Tida Ge Yaoyao Tong Zhenke Zhu Yangwu Deng Ahmed Fahmy Ming Chen Tin Mar Lynn Jinshui Wu Anna Gunina | 2021 | Ecosystem Health and Sustainability2021，7，1： | 0 |
| 16 | Experimental strategies to measure the microbial uptake and mineralization kinetics of dissolved organic carbon in soil显示文摘Soil organic matter turnover rates are typically estimated from mass loss of the material over time or from on rates of carbon dioxide production.In the study,we investigated a new way to characterize the concentration-dependent kinetics of amino acids used by measuring microbial uptake and mineralization of ^(14)C-alanine.We measured the depletion from soil solution after additions ^(14)C-alanine.The microbial uptake of ^(14)C-alanine from soil solution was concentration-dependent and kinetic analysis indicated the operation of at least three distinct alanine transport systems of differing affinities.Most of the ^(14)C-alanine depletion from the soil solution occurred rapidly within the first 10-30 min of the incubation after 10μM to 1 mM substrate additions.At alanine concentrations less than 250μM,the kinetic parameters for K_(m) and V_(max) of the higher-affinity transporter were 60.0μM and 1.32μmol g^(-1) DW soil h^(-1),respectively.The mineralization of alanine was determined and the half-time values for the rapid mineralization process were 45 min to 1.5 h after the addition at alanine concentrations below 1 mM.The time delay after its uptake into microbial biomass suggested that alanine uptake and subsequent respiration were uncoupled pattern.The microbial N uptake rate was calculated by microbial mineralization,and an estimated K_(m) value of 1731.7±274.6μM and V_(max )value of 486.0±38.5μmol kg^(-1)DW soil h^(-1).This study provides an alternative approach for measuring the rate of turnover of compounds that turnover very rapidly in soil. | Baozhen Li Tida Ge Paul W.Hill Davey L.Jones Zhenke Zhu Mostafa Zhran Jinshui Wu | 2020 | Soil Ecology Letters2020，2，3： | 0 |
