The ecological clusters of soil organisms drive the ecosystem multifunctionality under long-term fertilization

Environment International, Journal Year: 2022, Volume and Issue: 161, P. 107133 - 107133

Published: Feb. 8, 2022

Long-term fertilization is known to impact the biodiversity and community structures of soil organisms, which are responsible for multiple ecosystem functions (multifunctionality). However relationship between alterations organisms multifunctionality remains unclear, especially in case long-term fertilization. To explore contribution organismal multifunctionality, we took samples from a nearly 25-year field experiment. Organic matter significantly improved multifunctionality. Ecosystem was found be closely linked communities within major ecological clustering (Module 1) according trophic co-occurrence network, rather than entire organisms. This indicated that clusters network were critical maintaining The application organic could enrich specialized increase interactions cluster. As result, our findings emphasize role controlling after fertilization, presenting novel perspective on link

Influence of Agricultural Practices on Bacterial Community of Cultivated Soils

Agriculture, Journal Year: 2022, Volume and Issue: 12(3), P. 371 - 371

Published: March 6, 2022

Bacterial communities play an important role in maintaining stable functioning of soil ecosystems, participating decomposition plant residues, accumulation organic matter, formation aggregates and the cycle nutrients. For agroecosystems, diversity microbiocenosis is especially critical because they are essentially less dependent on external control. The agricultural practices used today (plowing, application synthetic fertilizers) can negatively affect richness bacterial communities. solution to this problem may be alternative farming methods preserve structural functional (reduced tillage, conservation no farming). Data composition for further forecasting impact agriculture development effective preserving increasing fertility. This review presents results recent studies Attention mainly paid effects applying inorganic fertilizers structure microbiocenosis; influence system (different cultivation, traditional systems); cover crops crop rotation microbial community soils.

Response of soil microbiota to various soil management practices in 100-year-old agriculture field and identification of potential bacterial ecological indicator

Ecological Indicators, Journal Year: 2024, Volume and Issue: 158, P. 111545 - 111545

Published: Jan. 1, 2024

The study aimed to comprehensively investigate the structural dynamics of a soil microbial community within 100-year agricultural field experiment. experimental design encompasses three distinct management practices, namely monoculture, five–year rotation, and random each with or without incorporation legumes manure. Soil communities were determined by Next-Generation Sequencing (Illumina MiSeq analysis) both V3 V4 hypervariable regions 16S rRNA gene for bacteria Archaea, as well ITS1 fungi. In all soils, dominant bacterial phyla Proteobacteria, Actinobacteria, Acidobacteria, Chloroflexi, orders Actinomycetales, Rhizobiales, Acidimicrobiales, Sphingomonadales. However, fungal Ascomycota, Basidiomycota, Zygomycota, Pleosporales, Eurotiales, Hypocreales, Mortierellales. Compared fallow land, affected soil, reducing ratio oligotrophs (e.g. Acidobacteria Armatimonadetes) copiotrophs (Actinobacteria Gemmatimonadetes). Moreover, contributed an increased number plant growth-promoting groups (PGPB), antagonistic many (e.g., Fusarium spp.) pathogens Bukholderiales, Xanthomonadales). generally in study, there no significant differences between monoculture crop rotations. two taxa can be considered potential indicators "healthy soil": nitrifying Nitrospira spp. whose abundance was strongly dependent on nitrogen, potassium, phosphorus, organic carbon, pH, PGP fungi genus Mortierellla which depended mainly nitrogen pH. Finally, most abundant especially rotation legumes, while soils did not favour these microorganisms. conclusion, various practices affect microbiota thus their ability support land productivity.

Quantitative assessment of the potential for soil improvement by planting Miscanthus on saline‐alkaline soil and the underlying microbial mechanism

Published: May 3, 2021

Abstract Phytoremediation using Miscanthus is a valuable technique for the restoration of saline‐alkaline soil, but potential not quantified. To assess this potential, 5 years field experiment was conducted on soils with three genotypes and an unplanted control. The bulk soil (0–20‐cm depth) physicochemical properties were measured annually from 2015 to 2018, while bacterial fungal community structures rhizosphere investigated by high‐throughput sequencing after under (2018). results showed that cultivation reduced salinization improved fertility site. Specifically, compared blank control, five‐years (mean different pooled) decreased pH 0.33 units (8.78–8.45) electrical conductivity 23.4 μS/cm (226.7–203.3 μS/cm), as well increasing organic matter content 18.9 34.9 g/kg total potassium 15.2 18.0 g/kg. In addition, improvement more pronounced longer duration growth. remediates altering microbial compositional abundance rather than its diversity. due enrichment beneficial bacteria leading desalinization (e.g., Gemmatimonadaceae), litter decomposition Chitinophagaceae), plant growth promotion Micrococcaceae), reduction harmful fungi Pleosporales Chitinophagaceae).
