“…Other studies focused on the interactions of tillage or N fertilization with crop rotation (Degrune et al, 2017; Ai et al, 2018). Only one study, carried out in a long-term vineyard experiment in Germany, found the interaction between soil tillage and N fertilization as major explanatory variable for the shift of soil bacterial and fungal communities (Pingel et al, 2019). In our study, despite the high degree of similarity in term of microbial composition among treatments, we firstly found that the prokaryotic and fungal community structure is strongly shaped by the interaction of tillage and N fertilization.…”

Soil biodiversity accomplishes key roles in agro-ecosystem services consisting in preserving and enhancing soil fertility and nutrient cycling, crop productivity and environmental protection. Thus, the improvement of knowledge on the effect of conservation practices, related to tillage and N fertilization, on soil microbial communities is critical to better understand the role and function of microorganisms in regulating agro-ecosystems. In the Mediterranean area, vulnerable to climate change and suffering for management-induced losses of soil fertility, the impact of conservation practices on soil microbial communities is of special interest for building mitigation and adaptation strategies to climate change. A long-term experiment, originally designed to investigate the effect of tillage and N fertilization on crop yield and soil organic carbon, was utilized to understand the effect of these management practices on soil prokaryotic and fungal community diversity. The majority of prokaryotic and fungal taxa were common to all treatments at both soil depths, whereas few bacterial taxa (Cloacimonates, Spirochaetia and Berkelbacteria) and a larger number of fungal taxa (i.e., Coniphoraceae, Debaryomycetaceae, Geastraceae, Cordicypitaceae and Steccherinaceae) were unique to specific management practices. Soil prokaryotic and fungal structure was heavily influenced by the interaction of tillage and N fertilization: the prokaryotic community structure of the fertilized conventional tillage system was remarkably different respect to the unfertilized conservation and conventional systems in the surface layer. In addition, the effect of N fertilization in shaping the fungal community structure of the surface layer was higher under conservation tillage systems than under conventional tillage systems. Soil microbial community was shaped by soil depth irrespective of the effect of plowing and N addition. Finally, chemical and enzymatic parameters of soil and crop yields were significantly related to fungal community structure along the soil profile. The findings of this study gave new insights on the identification of management practices supporting and suppressing beneficial and detrimental taxa, respectively. This highlights the importance of managing soil microbial diversity through agro-ecological intensified systems in the Mediterranean area.

“…These activities by microbiota then influence the diffusion and movement of resources through the soil. Soil management practices also modulate bulk soil microbiomes, as practices like cover crops and cultivation alter resource availability and edaphic factors like soil pH (Burns et al, 2016;Chou et al, 2018;Pingel et al, 2019). Thus, local soil characteristics are the primary driver shaping the extant pool of microorganisms that interact with grapevines, but geographic distance can also be related to differences in soil microbiomes.…”

Microbiomes are integral to viticulture and winemaking – collectively termed winegrowing – where diverse fungi and bacteria can exert positive and negative effects on grape health and wine quality. Wine is a fermented natural product, and the vineyard serves as a key point of entry for quality-modulating microbiota, particularly in wine fermentations that are conducted without the addition of exogenous yeasts. Thus, the sources and persistence of wine-relevant microbiota in vineyards critically impact its quality. Site-specific variations in microbiota within and between vineyards may contribute to regional wine characteristics. This includes distinctions in microbiomes and microbiota at the strain level, which can contribute to wine flavor and aroma, supporting the role of microbes in the accepted notion of terroir as a biological phenomenon. Little is known about the factors driving microbial biodiversity within and between vineyards, or those that influence annual assembly of the fruit microbiome. Fruit is a seasonally ephemeral, yet annually recurrent product of vineyards, and as such, understanding the sources of microbiota in vineyards is critical to the assessment of whether or not microbial terroir persists with inter-annual stability, and is a key factor in regional wine character, as stable as the geographic distances between vineyards. This review examines the potential sources and vectors of microbiota within vineyards, general rules governing plant microbiome assembly, and how these factors combine to influence plant-microbe interactions relevant to winemaking.

“…This phenomenon may occur because bacteria need more N per unit of accumulated nutrient biomass than fungi. Furthermore, changes in N inputs affect the bacterial activity and ultimately modulate the soil N fractions and their decomposability (Pingel et al, 2019). Similar consequences were found in the current research, in which bacterial diversity showed significant correlations with rhizosphere soil N fractions and enzyme activities across different agricultural practices (Table 3).…”

Cereal/legume intercropping is effective for reducing chemical fertilizer inputs and achieving sustainable development. However, the effects of intercropping combined with nitrogen (N) fertilization on rhizosphere soil microbial characteristics and N dynamics–enzyme activity relationships remain unclear. A field experiment was performed to analyze rhizosphere soil N fractions, related enzyme activities, and microbial communities on the Chinese Loess Plateau. The results showed that proso millet/mung bean intercropping (PM) combined with suitable N fertilization increased the total nitrogen (TN), ammonium (NH4+), nitrate (NO3−), and microbial biomass nitrogen (MBN) contents and enzyme activities, whereas the high N input (especially for N3) showed a decreasing trend. MBN was more closely associated with enzyme activities than were other N fractions. Intercropping and N fertilization strongly affected the bacterial and fungal diversity and community composition, as shown by a shift from K– to r–strategist dominance. Proteobacteria was the dominant bacterial phylum and was more abundant under intercropping than under sole cropping (SP), whereas Acidobacteria and Chloroflexi abundances were lower under PM than under SP. Ascomycota and Mortierellomycota were dominant fungal phyla whose abundances were significantly associated with rhizosphere soil N fractions and enzyme activities, although a high N input may inhibit microbial growth under intercropping systems. Overall, the observed changes in rhizosphere soil enzyme activities were most strongly affected by MBN driven by soil bacteria and fungi. These results provide scientific guidance for using rational fertilizer and further studying the mechanisms allowing reduced fertilizer use and increased efficiency under intercropping combined with N management.
