Nat Rev Microbiol. The soil csOTUs exhibited low to medium degrees of co-occurrence in the soil network (Fig. Our results also showed that treatment with organic fertilizer significantly decreased contents of Cd, Pb and As in tea leaves (Fig 3). Figure S11. PubMed Central The soil particle density is lower for soils with high organic matter content and higher for soil with higher mineral content. The association of Firmicutes OTUs to organic plots that receive manure fertilizer was found earlier [36]. 2010;26:13940. PubMed Central S7) was congruent with a separation by management type in CAP analysis of soil and root communities. By continuing you agree to the use of cookies. Root microbiome is an important determinant for plant growth and health by assisting in nutrient uptake, supporting abiotic stress tolerance and protecting the host from pathogens [20, 22]. Figure S5. PubMed https://doi.org/10.1371/journal.pone.0217018.s001, https://doi.org/10.1371/journal.pone.0217018.s002. Despite this emphasis, a much wider range of soil and catchment health aspects are improved as soil carbon is increased. Microbial communities of root and soil clearly separated along axis 1 (Additionalfile1: Fig. Nov. In an inventory on available national datasets, seven member states of the European Union have available datasets on organic carbon. - Graphical overview of data analysis. as "a characteristic microbial community occupying a reasonably well-defined habitat which has distinct physio-chemical properties. These micro-aggregates and macro-aggregates are bound together by transient binding agents (polysaccharides derived from plants and microorganisms) and temporary binding agents (fungal hyphae, fine roots, bacterial cells) (Oades, 1989; Tisdall and Oades, 1982). The textural components of soil, including sand, silt, and clay might result in aggregates as a result of their clumping. S5). For this, we combined the TMM normalized CPM counts of bacteria and fungi into separate OTU tables for the soil and root communities. Google Scholar. Many of them are bacteria of which there are around 1,000 species upon human skin from nineteen phyla. David D. Myrold, Peter J. Bottomley, in Methods in Enzymology, 2011. 1) explain the clear separation by compartment in the ordination analyses (Additionalfile1: Fig. Anderson MJ. 2012). Organically managed plots are fertilized with cattle slurry, did not receive synthetic herbicides or pesticides, and are subjected to either intensive tillage (IT) or reduced tillage (RT). Whereas Degens et al. https://doi.org/10.1371/journal.pone.0217018.t002. The analysis was conducted with 104 permutations and considered significant at p<0.05. ScienceDirect is a registered trademark of Elsevier B.V. ScienceDirect is a registered trademark of Elsevier B.V. Nannipieri P, Ascher J, Ceccherini MT, Landi L, Pietramellara G, Renella G. Microbial diversity and soil functions. That's one reason we're working with microbes to find new ways to protect #crops from disease. Biological/biochemical indicators are under-represented but show great potential. The PCR condition was initiated denaturation with 5 min at 95C, followed by 35 cycles of 40 s at 95C, 40 s at 58C, 60 s at 72C and final elongation with 5 min at 72C. The four types of soil are: I love the note is quite interesting Cookies policy. With increased availability of chemical fertilizers since the late 1970s and rise of labor costs since the 1980s, the utilization of organic fertilizer has dramatically declined [26, 28]. The soil microbiome governs biogeochemical cycling of macronutrients, micronutrients and other elements vital for the growth of plants and animal life. Here, we investigated soil and wheat root microbial communities in a cropping system experiment consisting of conventional and organic managements, both with different tillage intensities. Therefore, it is essential to understand the impact of nitrogen fertilizers beyond their effects on crop yield in order to achieve a balance between benefits and harms in modern agricultural practices. The effects of plant roots are well studied; they bind soil particles and aggregates together providing an additional apparent cohesion against shearing (Stokes, Atger, Bengough, Fourcaud, & Sidle, 2009). Soil, the critical component of the interconnected ecosystem, is the most biodiverse habitat on Earth, and soil microbiomes play a major role in human health and well-being through ecosystem services such as nutrient cycling, pollutant The pore size in soil affects the ability of plants and organisms to access water, oxygen, and other gases and minerals. The tea orchards were typical red acidity soils in southern China. Discriminating the effects of agricultural land management practices on soil fungal communities. However, increasing use and misuse of antimicrobials in humans and animals in recent decades has increased both the diversity and prevalence of antimicrobial resistance in soils, particularly in areas affected by human and animal wastes, such as organic manures and reclaimed wastewater, and also by air transmission. Gajic et al. 2015M580560). Besides, the cell walls of microbes can also join particles. We have previously shown that long-term tea cultivation with nitrogen fertilizers altered the bacterial composition of soil and significantly decreased soil pH and microbial metabolic activity, resulting in a reduction of beneficial bacteria [1, 45]. The networks were constructed using the Fruchterman-Reingold layout with 104 permutations as implemented in the R package igraph [92]. The composition of the soil microbiome presents the major driver in shaping the bacterial and fungal communities associated with plant roots [20, 21]. Additionally, we tested for differential OTU abundance between one or more of the cropping systems of soil and root communities (same thresholded OTU tables) of both kingdoms using likelihood ratio tests (LRT) with the R package edgeR [41]. Wittwer RA, Dorn B, Jossi W, van der Heijden MGA. S5), the soil bacteria network comprised the highest number of significantly co-occurring OTUs, followed by intermediate and similar numbers in the soil fungi and root bacteria networks (Additionalfile1: Fig. For example, the interplay between oxygen diffusion and microbial respiration results in a gradient of oxygen concentrations within a soil aggregate, which in turn influence denitrification (Sexstone et al., 1985). Topsoil ranges from 0.5% to 3.0% organic carbon for most upland soils. These cropping systems are, namely, conventional (C)and organic (O)management types, with different tillage intensities (no-tillage(NT), reduced-tillage(RT), and intensive tillage(IT)). 4 And the organic fertilizer improved tea quality and decreased the level of heavy metals in rhizosphere soil. Trends Ecol Evol. 2015;17:392403. S1) to investigate the effects of management type and tillage intensity on microbial communities.The bacterial community profiling yielded a total of 639,440 high-quality IPCC. In: Rosenberg E, DeLong EF, Lory S, Stackebrandt E, Thompson F, editors. (1996) observed no difference between the hot-water extractable carbohydrate carbon content of aggregated and nonaggregated soils, indicating that microbial polysaccharides were not in this case the dominant mechanism controlling aggregation. - Mean relative abundances of cropping sensitive OTUs at phylum and OTU level, respectively. It is important to stress that co-occurrence networks visualize correlative relationships between taxa that include true ecological interactions (e.g., mutualism), but also non-random processes (e.g., niche-overlap), and therefore, do not necessarily reflect direct interactions between taxa [33, 69]. (A) Weighted unifrac heatmap; (B) Hierarchical clustering analysis; (C) Principal Component Analysis. Associations with rhizosphere bacteria can confer an adaptive advantage to plants. Sandy soil is light, dry, and warm that tends to be more acidic than other types of soil. 2015. However, little is known of their vertical responses to restoration process and their contributions to soil nutrient cycling in the subsurface profiles. Soil is one of the most important elements of an ecosystem as it contains both. However, excessive use of chemical fertilizers has led to several issues such as serious soil degradation, nitrogen leaching, soil compaction, reduction in soil organic matter, and loss of soil carbon. Hence, the different cropping practices affected species richness to smaller degree than community composition. Grazing management that exposes soil (through either excessive or insufficient recovery periods) can also cause losses of soil organic carbon. 439450), a comparison of national data with modelled data is performed. Shaded areas represent the network modules containing csOTUs as defined in Additionalfile1: Figure S14. FAO Forestry Paper 168 Rome. Figure S3. Reganold JP, Wachter JM. In many soils, intensive cultivation degrades soil structure, which is a measure of the stability of soil aggregates. For operational taxonomic unit (OTU) delineation the 16S rRNA gene sequences were trimmed to the fixed length of 360bp, sorted by abundance, de-replicated, and clustered to OTUs (97%, singletons removed) with UPARSE [79]. 1996). If soil and root microbial communities are closely linked, root microbial communities may also be affected by agronomic practices [30]. In turn, one type of AgNPs prepared with the use of tannic acid (TA) increased bacterial load and activity. Glomalin also contributes to aggregate stabilization by sloughing off hyphae onto the surrounding SOM, binding to clays, and providing a hydrophobic coating (Wright and Upadhyaya, 1999). However, the full range of microbes Several rhizosphere organisms that foster aggregate formation through production of exopolysaccharides (EPS) have been identified and linked to improved soil structure of root-associated soil (Gouzou et al. Soil density usually depends on the soil texture and structure and the composition of the soil. Organic agriculture in the twenty-first century. The R script and all necessary input files are provided as Additionalfile5. Additionally, the growth of fungal hyphae has been observed to influence soil structure by aligning clay particles along hyphae, due to the stress exerted on soil particles during growth, possibly even forming microaggregates (Rillig & Mummey, 2006). In terms of synthetic fibers, it has been widely reported in geotechnical engineering that the addition of fibers increases soil strength (i.e., compressive, shear or tensile strength at failure) and increases strain to failure (i.e., increased ductile behavior) (e.g., Michalowski & ermk, 2003; Ranjan, Vasan, & Charan, 1996; Santoni, Tingle, & Webster, 2001). They also found a correlation between SOM and aggregate stability due to the cementing action of humus and other microbial by-products in cultivated and forested soils. 5). The importance of the microbiome of the plant holobiont. 2014;9:e108555. Estimates of -diversity (observed OTU richness) were calculated at each rarefaction level in QIIME (Additionalfile1: Fig. There is a growing consensus that the stability of soil microbial communities contributes to sustaining various ecological processes, including nutrient cycling (Pressler et al., 2020), soil organic carbon reservoirs and degradation (Wu et (2004) proposed that clay particles adhere to and encrust decomposing fragments of organic material in soil to form stable microaggregates, within less stable macroaggregates. Science. 15B, C) but, in none of the WSA classes was the carbon content in the silt+clay (s+c) fraction significantly affected (Fig. Peter Sale, Murray Hart, in Advances in Agronomy, 2021. Soil biota includes earthworms, nematodes, protozoa, fungi, bacteria and different arthropods.. Detritus resulting from plant senescence is the major source of soil Previous studies have verified the heavy metal polluted soil would affect the microbial community structure, microbial biomass and microbial residues [3739]. Front Microbiol. Carbonate minerals are the dominant form of soil carbon in desert climates. 2006. Cropping systems, including crop diversification, crop rotation and intercropping, and related agronomic practices used in agriculture impact soil health and quality from various spatial and temporal aspects (Vukicevich et al., 2016).Cropping systems were initially designed to maximize yield from agro-systems, but modern agriculture has become increasingly concerned Cite this article, A Correction to this article was published on 17 May 2020, A Correction to this article was published on 24 April 2018. Microbial taxa that frequently co-occur with other taxa in microbial co-occurrence networks are thought to be ecologically important and potentially play a key role within the microbiome [37, 38]. Together these comprise the soil food web, with the living component sustained by the biotic material component. These findings are intriguing; however, more research is needed to conclusively determine the primary function of these extracellular compounds. 31701329, 81573530), Fujian-Taiwan Joint Innovative Center for Germplasm Resources and Cultivation of Crop (Fujian 2011 Program, No.2015-75, China), the Natural Science Foundation of Fujian Province (No. There is a growing consensus that the stability of soil microbial communities contributes to sustaining various ecological processes, including nutrient cycling (Pressler et al., 2020), soil organic carbon reservoirs and degradation (Wu et They therefore have the textural requirements to respond to the structure-developing processes associated with biological activity. In addition, while long-term application of chemical fertilizers could lead to serious soil acidification, nutritional imbalance, and deterioration of the rhizosphere micro-ecological environment, further increased the activity of heavy metal ions in soil. 2010;91:46073. Plant host and soil origin influence fungal and bacterial assemblages in the roots of woody plants. [5] The balance of soil carbon is held in peat and wetlands (150 GtC), and in plant litter at the soil surface (50 GtC). The future research should focus the potential mechanism of intrinsic linkages between microbial community and heavy metal under the organic fertilizer treatments. Fungal Ecol. Rillig and Mummey (2006) outline three categories of mechanisms by which fungi (focused on arbuscular mycorrhizal fungi, AMF) can contribute to soil aggregate stability: (i) biophysical, (ii) biochemical, and (iii) biological mechanisms. Berlin-Heidelberg: Springer-Verlag; 2014. p. 79105. For example, we now know that a spoonful of agricultural soil contains 30,000 taxonomic varieties of microbes. Nevertheless, this study demonstrates that the CAST model is very powerful to predict the dynamics of soil aggregation and concurrent SOM change in response to changes in land use and soil management. A microorganism, or microbe, is an organism of microscopic size, which may exist in its single-celled form or as a colony of cells.. Soils containing greater than 1218% organic carbon are generally classified as organic soils. - Abundant cropping sensitive fungi fOTUs in soil. The proportion of soil organic matter that is protected increases with increasing clay concentrations in the soil (Golchin et al., 1994). Maize, tomato, and wheat actually decreased aggregate stability, while growth of perennial ryegrass and alfalfa tended to increase it. Natural variations in soil carbon occur as a result of climate, organisms, parent material, time, and relief. [25][26] Tropical deforestation represents nearly 25 percent of total anthropogenic GHG emissions worldwide. Image Source: Professor Patricia Shapley, University of Illinois. Soil color is determined primarily by the organic composition of the soil. (R 159 kb). Consistent with the -diversity analyses (Additionalfile1: Fig. AN was determined using the alkaline hydrolyzable method. Introduction. However, compared with plant, animal and human health, the importance of the soil microbiome and soil health has received less attention among one health researchers until now 7,8,9. Matson P, Parton W, Power A, Swift M. Agricultural intensification and ecosystem properties. In roots, we observed that organic csOTUs exhibited higher degrees of co-occurrence than conventional csOTUs. Plant roots and soil present different microbial habitats with specific sets of microbes (Fig. In order to prevent food shortage worldwide and maximize crop yield, large amounts of chemical fertilizers have been applied to arable fields over the past few decades [2930]. The concept of physical protection emphasizes the importance of aggregation in the processes of SOC stabilization and turnover (Christensen, 2001). The Supplementary Results comprise the global taxonomic profiles of soil and root bacterial and fungal communities and the taxonomic patterns of csOTUs. Yes https://doi.org/10.1186/s40168-017-0389-9, DOI: https://doi.org/10.1186/s40168-017-0389-9. We observed a significantly higher bacterial composition and Chao1 indices with samples from the organic fertilizer treatment group compared to samples from the chemical fertilizer treatment group. 15. The FAST experiment compares the 4 main cropping systems C-IT, C-NT, O-IT, O-RT. Wolfert S, Ge L, Verdouw C, Bogaardt MJ. FEMS Microbiol Ecol. As studies on agriculture and geology have increased, the soil is now considered a complex, dynamic, biogeochemical system that is vital to the life cycles of various land vegetation and soil-inhabiting organisms. Soil biota has the diverse and abundant intrinsic resistome. Table 2 summarized the chemical properties of soil from tea orchards treated with either organic or chemical fertilizers. Google Scholar. A growing body of research is highlighting the impacts root-associated microbial communities can have on plant health and development. In the root microbiome, we found that the management type was the most influential factor for the root bacteria, while tillage intensity explained most of the variation in the root fungi. Faust K, Raes J. Microbial interactions: from networks to models. Probing the active fraction of soil microbiomes using BONCAT-FACS. The unseen majority: soil microbes as drivers of plant diversity and productivity in terrestrial ecosystems. Sustainable agriculture is an important global issue. 2mm: >2mm; 250m: 250m2mm; 53m: 53250m. Click through the PLOS taxonomy to find articles in your field. Separate CAP ordinations using Bray-Curtis distance were performed for bacteria and fungi, both in roots and soil. The use of organic fertilizer could alleviate soil acidification, resulting in increased plant yields [14]. The cation exchange capacity of the soil is taken as an indicator of soil fertility, nutrient retention, and the ability of soil to protect groundwater from cation contamination. At the same time, non-rhizosphere soils were also collected from the organic (CKOrgS) and chemical (CKNorS) fertilizer treated tea orchards. Nat. Thangavel Ramesh, Oliver W. Freeman II, in Advances in Agronomy, 2019. These included: the total number of network nodes (representing OTUs), total number of edges (connections between nodes representing positive, significant correlations between OTUs), and degrees of co-occurrence (number of direct correlations to a node). Because of these concerns, there is a growing demand for development of organic agriculture. West Africa has experienced significant loss of forest that contains high levels of soil organic carbon. Root microbiomes of plants grown in the same soil differ between plant species and between genotypes within a species. Can rDNA analyses of diverse fungal communities in soil and roots detect effects of environmental manipulations--a case study from tallgrass prairie. c Qualitative taxonomic composition of cropping sensitive modules is reported as proportional OTUs numbers per class (bacteria) and phylum (fungi) and compared to the overall taxonomic distribution in the entire dataset (column all). Root exudates are another source of soil carbon. PLoS One. Effect of Tillage on Soil Aggregation of Four Indiana Soils after 5 Yearsa. Our motivation was to expand on these efforts by examining cropping system effects on root microbes and by also including the effect of tillage into the experimental design. Soil contains a vast diversity of microorganisms that can directly or indirectly modulate soil processes and terrestrial ecosystems. 2013;10:9968. [29], who reported that the NPK chemical fertilizers caused a significant decrease in bacterial diversity. Figure S4. The rhizosphere and non-rhizosphere soils of tea trees were taken from each experimental plot by a 5-point sampling method. 3.3) (Redmile-Gordon et al., 2020; Santos et al., 2020). 2015;18:133851. Tea polyphenols and caffeine contents were determined using a Waters HPLC system (C18 column: Inertsil ODS-SP, 4.6 250 mm, 5 m). Moreover, plant and human microbiomes are linked to each other: since the gut and the soil microbiome share similar bacteria phyla and since microbes from fruits, salads and vegetables join the human gut microbiome, the plant microbiome can affect the gut microbiome and thereby human health (Fig 2). By using this website, you agree to our Bipartite networks display cropping system specific OTUs in the soil and root bacterial and fungal communities as determined using indicator species analysis. Organic materials, such as humic matter and polysaccharides (plants, microbes), and impermanent bonding agents (fungi) help in stabilizing macro-aggregates. In this study, we found that the use of organic fertilizer significantly increased the amino acids content of tea (Fig 1). The FLASH method [20] was used to merge paired-end reads. 2008;40:1294305. All authors read and approved the final manuscript. Science. S1) to investigate the effects of management type and tillage intensity on microbial communities. Rhizosphere-mediated impacts on aggregate stability in bulk soil accrue over time and have been related to plant parameters such as total root biomass or root length (Rillig et al. - Defining cropping sensitive bacteria and fungi in soil and root samples. J Environ Manag. The roots were rinsed with tap water to remove soil debris, dried by blotting with sterile paper, and stored at 80C until DNA extraction. The gap between observations and model results points the way forward to develop further the detailed process descriptions in the CAST modeling approach, for example, to consider primary microaggregation directly from basic soil texture units. The shared number of exclusive OTUs between OrgS and NorS were 1022 (60.19%). Moreover, the structure of the soil is the determining factor for several important natural processes such as biogeochemical cycling, erosion resistance, carbon storage, and water inflow rate (Wright and Upadhyaya, 1998; Rillig and Steinberg, 2002; Saia et al., 2020). Yeoh YK, Paungfoo-Lonhienne C, Dennis PG, Robinson N, Ragan MA, Schmidt S, et al. Human activities are increasing antibiotic resistome at the global scale. Dormaar (1984) observed a reduction in carbohydrate content with decreasing aggregate size. Sci Rep. 2017;7 https://doi.org/10.1038/srep41911. Soil quality is one of the three components of environmental quality, besides water and air quality (Andrews et al., 2002).Water and air quality are defined mainly by their degree of pollution that impacts directly on human and animal consumption and health, or on natural ecosystems (Carter et al., 1997, Davidson, 2000).In contrast, soil quality A new method for non parametric multivariate analysis of variance. Data Availability: All relevant data are within the manuscript and its Supporting Information files. The government of Tanzaniatogether with the Food and Agriculture Organization of the United Nations[28] and the financial support of the government of Finlandhave implemented a forest soil carbon monitoring program[29] to estimate soil carbon stock, using both survey and modelling-based methods. We tested the effects of sample type and cropping system on observed species richness for each kingdom individually. Previous studies have attempted to understand the principles underlying the rhizosphere ecology and interactions between plants and PGPMs using ribosomal RNA The use of organic fertilizers can enhance crop yield and soil properties while restraining pests and diseases. https://doi.org/10.1371/journal.pone.0217018.g005. Bioinformatics. For each remaining sequences, the RDP classifier (Version 2.2) algorithm [23] was used to annotate taxonomic information via the GreenGen database [24]. Magdoff F. Concept, components, and strategies of soil health in agroecosystems.. volume6, Articlenumber:14 (2018) The libraries were sequenced on the MiSeq Instrument (Illumina, San Diego, USA) using a 600-cycle v3 Sequencing kit, paired-end 2300cycle sequencing mode at the Functional Genomics Center Zurich (www.fgcz.ch). The most abundantly identified bacteria phyla were assigned to the Actinobacteria, Chloroflexi, Proteobacteria, and Acidobacteria phyla. The gases found in soil include carbon dioxide, oxygen, and nitrogen. For example, Christensen (1992) found high organic matter in 0.251mm fractions. Sugiyama A, Vivanco JM, Jayanty SS, Manter DK. This pathogen of wheat causes Fusarium head blight disease, which is responsible for wheat yield losses worldwide [62]. Kshipra Gautam, Santanu Dasgupta, in Microalgae, 2021. Soil samples were collected from the rhizosphere of fields treated with organic fertilizer (OrgS) or chemical fertilizer (NorS) fon June 4, 2018. Wittwer et al. The scientific study of microorganisms began with their observation under the microscope in the 1670s by Anton van 2013;31:81421. The inorganic part of the soil is composed of rocks that are slowly broken down into smaller particles that might vary in size. Glomalin-related soil protein has been correlated with soil aggregate stability for AMF amended soils (e.g., Rillig, 2004; Wright & Upadhyaya, 1996, 1998) and is thought to act as a glue-like substance. Functions of Soil. Article Notably, the most influential cropping factors driving differences in soil communities were not necessarily the most influential in root communities. Aside from the environmental benefits of organic agriculture [13] and less intensive tillage regimes [10], there is still debate about the effects of these cropping practices on belowground microbial communities. Also, the microbial extracellular polysaccharides increase inter-particle cohesion and bind soil particles (Liu et al., 2005). Soil aggregation and development of soil structure play a crucial role in determining soil functions and ecosystem services in Earth's Critical Zone. Key Laboratory for Genetics, Breeding and Multiple Utilization of Crops, Ministry of Education / College of Crop Science, Fujian Agriculture and Forestry University, Fuzhou, China. The physical characteristics of an ecosystem have dramatic impacts on its succession in response to environmental perturbations ().System fluidity (connectivity) is expected to be a major factor in natural systems ranging from fluidic ecosystems (e.g., groundwater, rivers, ocean, lakes, wetlands, wastewater treatment plants, bioreactors, intestinal tract) to low or Conversely, root fungal communities did not strongly respond to management type induced changes in soil and instead were determined by changes in the tillage intensity. Table S5. Discover a faster, simpler path to publishing in a high-quality journal. 10.13140/RG.2.2.34636.00644. Comparing aggregate stability for soils inoculated with fungi with those inoculated with liquid media in which the microorganisms were grown, demonstrated that the binding agents remain in close association with the hyphae and are not excreted into the liquid/soil media (Aspiras, Allen, Harris, & Chesters, 1971). Jumpponen A, Johnson LC. The structure of glomalin has not been characterized so the true function of the glycoprotein remains unresolved and is an active area of research. Abarenkov K, Henrik Nilsson R, Larsson K-H, Alexander I, Eberhardt U, Erland S, et al. The root fungi network comprised the fewest OTUs and was the least complex. We thank Dr. Lucy Poveda from the Functional Genomics Centre Zurich for technical support in MiSeq sequencing and Dr. Diane Brge from Agroscope for performing the physical and chemical analyses of the soil samples. Soil Forming Processes. Correlation detection strategies in microbial data sets vary widely in sensitivity and precision. PERMANOVA also confirmed a general effect of cropping system, but no pairwise differences on community dissimilarity were found. Ernest SKM, Brown JH. N. Li, S.A. Banwart, in Advances in Agronomy, 2017. [25] and is available under the study accession PRJEB15152 (Sample: SAMEA54297418). Treatment with organic fertilizer resulted in significantly lower contents (P < 0.05) of cuprum (Cu), plumbum (Pb) and cadmium (Cd) in rhizosphere soils compared to the chemical fertilizer treatment group. Inductively coupled plasma mass spectrometry No, Is the Subject Area "Rhizosphere" applicable to this article? Introduction. Irshad Mahmood, in Microbiomes and Plant Health, 2021.
