“…Most of the studies analysing fungal communities in agricultural soils found Sordariomycetes as the dominant class, followed by other classes of Ascomycota, like Dothideomycetes and Eurotiomycetes. Agaricomycetes often account for much less than 10% of relative abundance (Balami et al, 2021 ; Clocchiatti et al, 2021 ; Dang et al, 2018 ; Fraç et al, 2018 ; Klaubauf et al, 2010 ; Naumova et al, 2022 ). The soil amendment with wood‐based materials, such as beech, seems to lead to an increase in Agaricomycetes (Clocchiatti et al, 2023 ; Malewski et al, 2023 ).…”

Microbial diversity profoundly influences soil ecosystem functions, making it vital to monitor community dynamics to comprehend its structure. Our study focused on six agrosystems in Madeira Archipelago, analysing bacteria, archaea, fungi and AMF through classical microbiology and molecular techniques. Despite distinct edaphoclimatic conditions and management practices, bacterial structures exhibited similarities, with Alphaproteobacteria at 18%–20%, Bacilli at 11%–18% and Clostridia at 9%–14%. The predominance of copiothrophic groups suggested that soil nutrient content was the driver of these communities. Regarding archaea, the communities changed among sites, and it was evident that agrosystems provided niches for methanogens. The Crenarchaeota varied between 15% and 29%, followed by two classes of Euryarchaeota, Methanomicrobia (17%–25%) and Methanococci (4%–32%). Fungal communities showed consistent composition at the class level but had differing diversity indices due to management practices and soil texture. Sordaryomycetes (21%–28%) and Agaricomycetes (15%–23%) were predominant. Conversely, AMF communities appeared to be also influenced by the agrosystem, with Glomus representing over 50% of the community in all agrosystems. These insights into microbial groups' susceptibilities to environmental conditions are crucial for maintaining healthy soil and predicting climate change effects on agrosystems' productivity, resilience and sustainability. Additionally, our findings enable the development of more robust prediction models for agricultural practices.

“…In Spain, the vineyard tillage inhibited the diseaseresistant Trichoderma populations in the soil [139], which makes us wonder whether NT would boost beneficial fungi to attain the disease-suppressive soil [140]. In the south of West Siberia, half of the identified OTUs (operational taxonomic units) were Ascomycota [13], and the phyla Basidiomycota, Zygomycota, Mortierellomycota, Chytridiomycota, and Glomeromycota showed tillage-related differential abundance. Wheat residues could increase the abundance of dominant genera Mortierella, Chaetomium, Clonostachys, Gibberella, Fusarium, and Hypocrea as compared with undisturbed soil.…”

“…Such concerns have led to the search for tillage systems that minimize negative impacts on the environment while cost-effectively sustaining crop productivity [8]. Conservation tillage techniques, such as minimum tillage (MT ≈ reduced tillage (RT)) [9], no-tillage (NT; zero tillage) [10], and organic mulch [11,12], minimize the impacts of tillage on soil structure and soil biota [13], reduce soil erosion threats, increase soil organic carbon (SOC) [1], and may help reduce GHG emissions in comparison to conventional tillage (CT) [14]. To achieve these goals, conservation tillage should be adapted in terms of local conditions and flexibly implemented in crop production systems.…”

Ecological cultivation is a promising regime for medicinal plant production. For a long time, unreasonable farming methods have threatened soil health and medicinal agriculture and restricted the sustainable development of ecological agriculture for medicinal plants. However, there is a lack of comprehensive discourse and discussion about the pros and cons of different tillage regimes. Here, the research trend and application prospects of no-tillage (NT) are comprehensively reviewed, and the ecological benefits, challenges, and opportunities of the NT system in ecological agriculture of medicinal plants are scrutinized, aiming to call for an about-face in the sustainable conservation and utilization of both phytomedicine resources and agricultural/ecological resources. An exhaustive literature search in PubMed, Bing, Scopus, and CNKI was performed to outline the research trend in conservation tillage and medicinal plants during the recent four decades. The application of NT has a long history and can reduce tillage frequency and intensity and protect soil from erosion and deterioration. NT is often combined with organic mulch to significantly reduce soil disturbance. NT and stover mulching have the advantages of saving manpower and resources and improving soil quality, crop yield, and quality. The ecological and economic benefits of NT in long-term medicinal plant cultivation could be prominent. In developing medicinal plant cultivation, competing with food crops should be avoided as much as possible, and the impact on the production of major grain crops should be minimized. Therefore, the full utilization of soil resources in forests, mountains, and wasteland is advocated, and sustainable soil utilization is the core issue in the process of land reclamation. NT and stover mulching not only inherit the traditional concept of “natural farming”, conform to the basic laws of ecology, as well as the growth characteristics of medicinal plants, but also protect the ecological environment of the production area. It would become the core strategy of ecological agriculture for medicinal plants. Our summary and discussions would help propose countermeasures to popularize NT and organic mulch, promote relevant research and scientific allocation of resources, and adapt to local conditions to achieve precise management and harmonize conservation and production of medicinal plants.

“…The area where the field trial was performed was described earlier in our report about soil mycobiomes [10] (https://www.mdpi.com/2075-1729/12/8/1169, accessed on 23 August 2023). Briefly, the experimental field was located in the Novosibirsk region, Russia (54 • 4 6 N, 79 • 36 3 E) in the forest-steppe zone with a sharply continental climate and Luvic Endocalcic Chernozem (Siltic) [11] veing the most prevalent and agriculturally important soil of the region.…”

Managing soil biodiversity using reduced tillage is a popular approach, yet soil bacteriobiomes in the agroecosystems of Siberia has been scarcely studied, especially as they are related to tillage. We studied bacteriobiomes in Chernozem under natural steppe vegetation and cropped for wheat using conventional or no tillage in a long-term field trial in the Novosibirsk region, Russia, by using the sequence diversity of the V3/V4 region of 16S rRNA genes. Actinobacteria, Acidobacteria, and Proteobacteria summarily accounted for 80% of the total number of sequences, with Actinobacteria alone averaging 51%. The vegetation (natural vs. crop) and tillage (ploughed vs. no-till) affected the bacterial relative abundance at all taxonomic levels and many taxa, e.g., hundreds of OTUs. However, such changes did not translate into α-biodiversity changes, i.e., observed and potential OTUs’ richness, Shannon, and Simpson, excepting the slightly higher evenness and equitability in the top 0–5 cm of the undisturbed soil. As for the β-biodiversity, substituting conventional ploughing with no tillage and maintaining the latter for 12 years notably shifted the soil bacteriobiome closer to the one in the undisturbed soil. This study, presenting the first inventory of soil bacteriobiomes under different tillage in the south of West Siberia, underscores the need to investigate the seasonality and longevity aspects of tillage, especially as they are related to crop production.
