Quast C, Pruesse E, Yilmaz P, Gerken J, Schweer T, Yarza P, et al. Briefly, the bacteria OTUs (bOTUs) and taxonomy tables were filtered to exclude OTUs classified as chloroplasts and mitochondria. S1) to investigate the effects of management type and tillage intensity on microbial communities. We visualized the significant (p < 0.05) OTU associations to one or more of the different cropping system from the indicator species analysis using bipartite networks. Similarly, we identified 62 and 36 csOTUs for root bacteria and fungi, corresponding to an effects size of 14.2 and 5.0%, respectively. Next, we explored the distribution patterns of csOTUs in meta co-occurrence patterns of bacteria and fungi in soil and root communities (Fig. For this, we combined the TMM normalized CPM counts of bacteria and fungi into separate OTU tables for the soil and root communities. 2006;72:7804–12. Figure S5. For instance, the high number of soil bacteria OTUs that were shared between the intensive tillage reflects the close clustering of these samples in the ordination. PERMANOVA confirmed the significant effect of cropping systems on both soil microbial communities (Additional file 1: Table S4). In: Innis M, Gelfland D, Sninsky J, White T, editors. Google Scholar. Appl Environ Microbiol. Article  Briefly, the FAST experiment comprises two replicates established beside each other on the same field. Dissimilarities in soil bacteria were generally driven by differences in tillage regimes, whereas management type, together with tillage, was influential for the soil fungi. Diversification is also a viable option to mitigate the risk of climate change. Similarly, management type presented the main driver in root communities (Fig. With the exception of five root bacteria OTUs, the majority of keystone OTUs was not sensitive to cropping practices (Table 1, Additional file 1: Table S5). Figure S9. 2011;21:2957–63. 2013;28:230–8. What is the difference between mixed farming and mixed cropping? It is essential that the program of feeds and fodder development should provide to the production and multiplication of seeds and planting materials of recommended fodder crops. The term cropping system refers to the crops, crop sequences and management techniques used on a particular agricultural field over a period of years. Appl Soil Ecol. Bipartite networks display cropping system specific OTUs in the soil and root bacterial and fungal communities as determined using indicator species analysis. Bommarco R, Kleijn D, Potts SG. 2003;54:655–70. Big data in smart farming - a review. Microbial community structure and its functional implications. QIIME allows analysis of high-throughput community sequencing data. and Figure S8. Nat Plants. Taxonomy assignment was performed using the SILVA database (v119; [82] with the RDP classifier as implemented in QIIME [83]. A single crop can’t suffice their family needs. The composition of the soil microbiome presents the major driver in shaping the bacterial and fungal communities associated with plant roots [20, 21]. 2012;17:478–86. Faria JC, Jelihovschi EG, Allaman Bezerra I. TukeyC: conventional Tukey test. 2011;27:863–4. 2004;5:515–25. S6) into the microbial networks, and we found them agglomerating according to management type and/or tillage intensity (Additional file 1: Fig. We discuss the cropping system effects on soil microbial communities and on microbial α-diversity in the Supplementary Discussion. Such information is relevant for implementing agricultural management strategies to promote specific microbes that contribute to soil fertility and plant health. - PCR cycling conditions. Changes in bacterial community structure of agricultural land due to long-term organic and chemical amendments. The bacterial community profiling yielded a total of 639,440 high-quality sequences (range 11,192–37,255; median 18,122; Additional file 2). - Abundant cropping sensitive fungi fOTUs in soil. We assume that the soil microbiome would exhibit the most pronounced differences in response to tillage or manure fertilization shortly after application and that such effects would gradually decline over the length of the growing season until a soil-type specific equilibrium is reached again after disturbance. Hello, I am Siddartha Reddy . For small farmers, it’s a huge boon to do mixed farming and mixed cropping. - Taxonomic profiles at phylum level. Difference Between a Donkey, Ass and Mule. - Separate co-occurrence networks of bacteria and fungi in soil and root samples. A full-factorial design would formally require an “O-NT” treatment instead of an “O-RT” treatment. Appl Environ Microbiol. All statistical analyses were conducted in R v3.3.0 [85]. One crop should require less and others the more. Agler MT, Ruhe J, Kroll S, Morhenn C, Kim ST, Weigel D, et al. Mercado Vergnes D, Renard ME, Duveiller E, Maraite H. Identification of Alternaria spp. Keeping in mind the mixed crops are sown in a single hole. Plant Dis. What is Ghana Jeevamrutham and how to make it? 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].

Environmental impact of different agricultural management practices: conventional vs. organic agriculture. Agroforestry is a land use management system in which trees or shrubs are grown around or among crops or pastureland. PLoS Biol. - Abundant cropping sensitive fungi fOTUs in soil. FEMS Microbiol Ecol. This finding suggests the hypothesis that manure application to soil may introduce taxa to the root microbiome with keystone function. If a farmer is dependent on the single crop which is water-intensive and rains don’t make in time. If there are heavy rains then one crop will survive and the same applies during drought condition. In general, arable management affects community composition and diversity; although such effects may depend on the microbial kingdom being studied and the different farming systems being compared [14, 15]. The networks were constructed using the Fruchterman-Reingold layout with 104 permutations as implemented in the R package igraph [92]. Goat Feed – What to feed and How much to feed? Ihrmark K, Bödeker ITM, Cruz-Martinez K, Friberg H, Kubartova A, Schenck J, et al. Supplementary Figures: Figure S1. Manage cookies/Do not sell my data we use in the preference centre. All networks were visualized with the Fruchterman-Reingold layout with 104 permutations in igraph. Root and soil-specific OTUs were colored in green and brown, respectively, and non-differentially abundant OTUs are in gray (likelihood ratio test, p < 0.05, FDR corrected). An amendment to this paper has been published and can be accessed via the original article. The whole produce for that season is lost. 1). 2012;10:538–50. Figure S6. Figure S9. 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. The FAST experiment compares the 4 main cropping systems C-IT, C-NT, O-IT, O-RT. Choosing crops in such a way that one requires a lot of sunlight and others should be using less. 2015;112:E911–20. Schmieder R, Edwards R. Quality control and preprocessing of metagenomic datasets. Canonical analysis of principal coordinates: a useful method of constrained ordination for ecology. (3) How do cropping practices impact co-occurrence patterns of soil- and root-associated microbes? Haney CH, Samuel BS, Bush J, Ausubel FM. FEMS Microbiol Ecol. Front Microbiol. We visualized and quantified the differences between microbial communities (β-diversity) using unconstrained principal coordinate analysis (PCoA) and permutational multivariate analysis of variance (PERMANOVA) on Bray-Curtis dissimilarities. The Farming System and Tillage experiment (FAST) was established in 2009 near Zürich to address this for the main arable cropping systems in Switzerland (Additional file 1: Fig. For example, the effect of tillage intensity in the soil communities was apparent with a discrete module (M1) in the soil network, containing csOTUs specific to intensive tillage practices. The SILVA ribosomal RNA gene database project: improved data processing and web-based tools. Cropping System Definitions The term cropping system refers to the crops and crop sequences and the management techniques used on a par-ticular field over a period of years. ) was plotted as a function of their degree of co-occurrence. 2015;1:1–9. Figure S2. Busby PE, Soman C, Wagner MR, Friesen ML, Kremer J, Bennett A, et al. Pimentel D, Harvey C, Resosudarmo P, Sinclair K, Kurz D, McNair M, et al. and Figure S8. Hence, the possible introduction of microbes from manure and their particular influence on root microbiome functioning presents a high research priority. The challenge of food security. Proc Natl Acad Sci. In some places, the rainy season is long enough to grow two crops: either two main crops, or one main crop followed by a cover crop. Sequential Cropping involves growing two crops in the same field, one after the other in the same year. A PDF containing supplementary methods, results, discussion, references, figures and tables. In contrast, the csOTUs in the root microbiome—in particular the ones that were sensitive to organic farming—included members with high degrees of co-occurrence (see keystones below). Plant host and soil origin influence fungal and bacterial assemblages in the roots of woody plants. Consequently, network connectivity (measured by average number of connections per OTU) was higher in the soil bacteria and soil fungi networks than the root bacteria network. 7.3.5 Sequence Cropping/Double Cropping. We then constructed meta-networks to visualize correlations between bacteria and fungi in the soil and root communities. Weed management in sequential cropping is a little different from those in intercropping systems. S13). Springer Nature. The Supplementary Methods contain the details about the chemical soil analysis, PCR setup, library preparation and sequencing. A number of recent microbial community surveys have described the root microbiomes of Arabidopsis thaliana [23, 24], clover [25], maize [26], rice [27], sugarcane [28], and grapevine [29] and reported significant effects of soil type on root microbiome composition. 2013;8:e56329. But in the Mixed crop, the risk is very low. In anyway its a win-win situation for the farmer. Cookies policy. Ordination analyses were performed using the R package phyloseq [87]. The cropping pattern is determined by rainfall, climate, temperature, soil type and technology; thus it changes over space and time. While cropping pattern refers to the yearly sequence and spatial arrangement of crops or of crops and fallow in a particular land area; Cropping system refers to cropping pattern as well as its interaction with resources; technology, environment etc . X-axis reports average OTU abundance (as counts per million, CPM), and Y-axis log2-fold change (root relative to soil). Soil Biol Biochem. 2012;6:343–51. Mixed cropping is a proven age-old technique that is risk-proof. The libraries were sequenced on the MiSeq Instrument (Illumina, San Diego, USA) using a 600-cycle v3 Sequencing kit, paired-end 2 × 300 cycle sequencing mode at the Functional Genomics Center Zurich (www.fgcz.ch). Mol Ecol. Estimates of α-diversity (observed OTU richness) were calculated at each rarefaction level in QIIME (Additional file 1: Fig. 4c), revealing that the different cropping practices do not target specific microbial lineages. 2014;9:1177–94. S14). Depending on their family needs the crops are grown. New Phytol. ISME J. Crops are carefully chosen in order to help each other. Geographic patterns of co-occurrence network topological features for soil microbiota at continental scale in eastern China. Ziemer CJ. The system is characterized by a typical farm type or household livelihood pattern, and significant sub-types are described where appropriate. The association of Firmicutes OTUs to organic plots that receive manure fertilizer was found earlier [36]. CAS  2016;97:188–98. All samples in this study were collected from the Farming Systems and Tillage (FAST) experiment near Zürich, Switzerland (47° 26′ 20″ N 8° 31′ 40″ E). 2010;91:460–73. (PDF 2862 kb), An XLSX table contains the experimental design (Sample ID, sample type and cropping system), chemical soil data and sequencing information (barcodes and sequence counts). Hence, the different cropping practices affected species richness to smaller degree than community composition. Supplementary Tables: Table S1. We identified cropping sensitive csOTUs in both soil and root microbial communities (Additional file 1: Fig. Table S3. We calculated the network properties mentioned above, and additionally, to explore community structure within the soil and root meta-networks, we identified network modules. The entire root systems were first lyophilized for 48 h and then ground to a fine powder in a ball mill. McMurdie PJ, Holmes S. Phyloseq: an R package for reproducible interactive analysis and graphics of microbiome census data. Cropping Systems 2.1 Mixed cropping Mixed cropping is the practice of growing more than one crop in a field at a given time. In summary, while tillage-driven differences were seen in the soil bacterial community, the management type appeared to be the main driving factor in root bacteria. Lastly, we explored the extent to which management types and tillage regimes impacted co-occurrence patterns in microbial communities. Plant roots and soil present different microbial habitats with specific sets of microbes (Fig. Mixed cropping is a very old cropping formula against crop failure due to abnormal weather conditions. Transforming Triple Cropping System to Four Crops Pattern: An Approach of Enhancing System Productivity through Intensifying Land Use System in Bangladesh. However, there are few agricultural experiments comparing conventional and organic farming practices [16] and fewer that compare different management types and tillage intensities [17]. 2014;80:574–85. This work was supported by a grant from the Swiss National Science Foundation SNSF (grant PDFMP3_137136) awarded to MVDH and Bernhard Schmid (University of Zurich, Switzerland). S3). It was recently shown that soils under conventional and organic management harbor distinct microbial networks in each farming system [38]. Figure S2. For the in-depth assessment of soil and root bacterial and fungal communities, we performed Spearman rank correlations between all pairs of bacteria and all pairs of fungi OTUs within the soil and root communities separately. - Rarefaction curves. Such experiments would include, e.g., the quantification of cropping-induced microbiome differences of soil and root samples in time series throughout the growing season or manure application tests that uncouple nutritional from microbial components (e.g., applications of nutrient-free microbial extracts from slurry or extracts with inactivated slurry microbiota).

Defining the core Arabidopsis thaliana root microbiome. How many tilapia can go in a 100 gallon tank? In both soil and root meta-networks, we identified modules containing high proportions of OTUs responding similarly to different cropping practices (Fig. To date, the effects of agricultural practices on root microbial communities remain still poorly understood, owing to contrasting reports and the use of low-resolution fingerprinting methods [31]. Chaparro JM, Badri DV, Vivanco JM. - Defining modules in root and soil networks. PubMed  (XLSX 278 kb), A zip archive comprising the command line code and necessary input files needed to replicate bioinformatic analysis. Although inference of ecological function from OTU data must be interpreted cautiously, we inspected the csOTUs for taxa with known functions of potential importance in agriculture. We see support for this idea as there is a marked impact of organic management on the root bacteria and not on soil (Figs. 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). Hartmann M, Widmer F. Community structure analyses are more sensitive to differences in soil bacterial communities than anonymous diversity indices. Current cropping systems in the American heartland have developed within a specific set of social, economic, and ecological conditions. 1999;96:5995–6000. Changes in soil microbial community structure with tillage under long-term wheat- fallow management. Crops are chosen in Mixed cropping such a way that no crop competes for resources like sunlight, nutrients, water, root pattern, crop duration. For example, in combination with reference stocks of microbial isolates, plant growth experiments can be conducted in which the presence/absence or relative abundance of keystone taxa identified by network analysis can be manipulated and the effects on plant growth and development can be scored [65]. The first replicate started in summer 2009 (FAST I) and the second in summer 2010 (FAST II), following a staggered start design. ‘Cropping pattern’ and ‘cropping system’ are two terms used interchangeably; however these are two different concepts. For this, we randomly selected one file containing α-diversity estimations at 11,000 (bacteria) and 9000 (fungi) sequences per sample from QIIME. We also mapped the csOTUs (as defined in Additional file 1: Fig. A mix of crops with a short duration and a long duration. Members of the soil and root microbiome interact directly and indirectly with each other, and a tool for better understanding of these potential interactions is co-occurrence network analysis [32, 33]. The roots were rinsed with tap water to remove soil debris, dried by blotting with sterile paper, and stored at − 80 °C until DNA extraction. Terms and Conditions, The legumes will not only provide nutritious fodder for sheep without adversely affecting the grain yield but will also improve the soil fertility through nitrogen fixation which in turn will be available to the grain crop. Nucleic Acids Res. Trends Plant Sci. While the identified csOTUs responded to specific cropping systems, they did not exhibit a particular taxonomic pattern with cropping system (Additional file 1: Figs. Lentendu G, Wubet T, Chatzinotas A, Wilhelm C, Buscot F, Schlegel M. Effects of long-term differential fertilization on eukaryotic microbial communities in an arable soil: a multiple barcoding approach. Ernest SKM, Brown JH. We first constructed separate co-occurrence networks for soil and root bacterial and fungal communities and determined their properties (see the “Methods” section). Inter-cropping is a system where two or more crops are grown in proximity. Google Scholar. Chaudhry V, Rehman A, Mishra A, Chauhan PS, Nautiyal CS. Finally, we defined the OTUs that were supported by both methods as cropping sensitive OTUs (hereafter: csOTUs). The cropping systems are referred to as organic with intensive tillage (O-IT) and organic with reduced tillage (O-RT). Faust K, Raes J. Microbial interactions: from networks to models. These examples could suggest that less intensive tillage systems may favor potentially pathogenic taxa. Barberan A, Bates ST, Casamayor EO, Fierer N. Using network analysis to explore co-occurrence patterns in soil microbial communities. Crop and varietal diversification of the rice based cropping systems may improve the productivity and profitability of the systems. Klaus Schlaeppi. S10). 1997;277:494–9. Mixed cropping obviously reduces pest infestation. We constructed two types of co-occurrence networks. Soil and roots harbor specific sets of microbes. 2012;64:450–60. PubMed  The type of sensitivity of these module members to the specific cropping systems (Fig. The formula is simple and based on a lot of common sense involved. Plant Pathol. Article  ISME J. Responses of soil fungi to 5-year conservation tillage treatments in the drylands of northern China. Monocropping reduces soil fertility and destroys the structure of the soil. However, the effects of management types and different tillage intensities on belowground microbial communities at the site have not been explored. The rhizosphere microbiome and plant health. A balance of nutrient availability is maintained. Martin M. Cutadapt removes adapter sequences from high-throughput sequencing reads. It is possible that the higher abundance of these OTUs is a direct result of manure application, as bacteria from these families have previously been isolated from cattle manure [59] or reported in such community surveys [60] and are also common in waste products of other livestock [61].
