“…Many studies performed on one soil have found tillage to affect fungal community structures (Hartmann, Frey, Mayer, Mäder, & Widmer, 2015;Legrand et al, 2018;Sharma-Poudyal et al, 2017;Sommermann et al, 2018;Wang, Chen, Liu, Wen, & Liao, 2016), whereas a global meta-analysis showed that fungal diversity was not consistently affected by tillage (Li et al, 2020). The effects of tillage have been linked to disturbances and changes in ecosystem stability (Wagg et al, 2018).…”

“…However, it is likely that these effects are at least partially dependent on local conditions, including soil type, climatic conditions and soil abiotic factors (Tedersoo et al, 2014). A recent meta-analysis showed that tillage affected significantly and consistently the soil bacterial community, whereas there were no consistent effects on fungi (Li et al, 2020). Yet, different methodologies (i.e., primers and DNA extraction kits) used in different studies hamper the inference of conclusions across studies (Ramirez et al, 2018).…”

Cropping practices have a great potential to improve soil quality through changes in soil biota. Yet the effects of these soil-improving cropping systems on soil fungal communities are not well known. Here, we analysed soil fungal communities using standardized measurements in 12 long-term experiments and 20 agricultural treatments across Europe. We were interested in whether the same practices (i.e., tillage, fertilization, organic amendments and cover crops) applied across different sites have predictable and repeatable effects on soil fungal communities and guilds. The fungal communities were very variable across sites located in different soil types and climatic regions. The arbuscular mycorrhizal fungi (AMF) were the fungal guild with most unique species in individual sites, whereas plant pathogenic fungi were most shared between the sites. The fungal communities responded to the cropping practices differently in different sites and only fertilization showed a consistent effect on AMF and plant pathogenic fungi, whereas the responses to tillage, cover crops and organic amendments were site, soil and crop-species specific. We further show that the crop yield is negatively affected by cropping practices aimed at improving soil health. Yet, we show that these practices have the potential to change the fungal communities and that change in plant pathogenic fungi and

“…Evaluation of 43 works in meta‐analyzes observed that no‐tillage increased the relative abundance of Acidobacteria , decreased Actinobacteria , and had little effect on Proteobacteria , Chloroflex , Firmicutes , and Bacteroidetes (Y. Li et al, 2020). In the same work, Li and colleaguies demonstrated that there was an increase in microbial diversity under no‐tillage.…”

“…But they are still incipient in relation to information about irrigated rice in lowlands under no‐tillage long term (>20 years) and its relationship with changes in the activity of extracellular enzymes and the microbial profile of the soil (Carlos et al, 2020). The soil bacterial community in general is more affected by different soil managements than the fungal community (Y. Li et al, 2020). Thus, the research work focuses more on bacterial changes in the soil in different management systems.…”

A long‐term no‐tillage system can increase enzymatic activity and maintain bacterial richness in paddy fields

Soil management systems cause many changes in the microenvironment that directly affect activity and diversity of microorganisms. In lowlands, there is a gap in relation to the adoption of no-tillage (zero-tillage) and the impact it has on soil under cultivation of irrigated rice. This study, an in-field experiment, evaluated the microbial enzymatic activity and diversity in an Entisol cultivated with rice under different managements for 22 years. The experiment started in the 1994/95 growing season, and the treatments were no-tillage, conventional, and pregerminated management systems. After 22 years, the data obtained on most of the evaluation dates indicated that no-tillage increased microbial biomass carbon (+45%), microbial biomass nitrogen (+54%), and basal respiration (+54%). No-tillage compared to management under soil tillage (pregerminated and conventional tillage) increased the activity of β-glucosidase (+43%), acid phosphatase (+68%), diacetate fluorescein (+34%), and urease (+96%).The enzyme activity was correlated with the soil organic carbon content and particulate fraction. Despite the relatively high enzyme activity with no-tillage, bacterial richness was maintained in this soil management system. The Proteobacteria phylum has a greater abundance in the NT (43.2%) in relation to the CT (32.3%). Bacteroidetes phylum has a lower abundance in the NT (10.0%) in relation to the CT (15.2%). The Verrucomicrobia phylum has a greater abundance in NT (8.9%) in relation to CT (4.9%). The results suggest that no-tillage is an important management tool in the recovery of irrigated rice areas whose soil has undergone microbiological degradation.

“…Not surprisingly, they found that organic farming increased richness, decreased evenness, and shifted the structure of the soil microbiota when compared with conventionally managed soils under mineral fertilization ( Hartman et al, 2018 ; Li et al, 2020b ). There also are reports of significant alterations in the microbial community composition of both summer maize and winter wheat in response to increased nitrogen fertilization dose ( Wang et al, 2018 ; Li et al, 2020a ). Clearly, a better understanding of the interactions between the soil microbiome and conventional agricultural practices is crucial for the development of sustainable management of soil fertility and crop production.…”

Microbe to Microbiome: A Paradigm Shift in the Application of Microorganisms for Sustainable Agriculture

Light, water and healthy soil are three essential natural resources required for agricultural productivity. Industrialization of agriculture has resulted in intensification of cropping practices using enormous amounts of chemical pesticides and fertilizers that damage these natural resources. Therefore, there is a need to embrace agriculture practices that do not depend on greater use of fertilizers and water to meet the growing demand of global food requirements. Plants and soil harbor millions of microorganisms, which collectively form a microbial community known as the microbiome. An effective microbiome can offer benefits to its host, including plant growth promotion, nutrient use efficiency, and control of pests and phytopathogens. Therefore, there is an immediate need to bring functional potential of plant-associated microbiome and its innovation into crop production. In addition to that, new scientific methodologies that can track the nutrient flux through the plant, its resident microbiome and surrounding soil, will offer new opportunities for the design of more efficient microbial consortia design. It is now increasingly acknowledged that the diversity of a microbial inoculum is as important as its plant growth promoting ability. Not surprisingly, outcomes from such plant and soil microbiome studies have resulted in a paradigm shift away from single, specific soil microbes to a more holistic microbiome approach for enhancing crop productivity and the restoration of soil health. Herein, we have reviewed this paradigm shift and discussed various aspects of benign microbiome-based approaches for sustainable agriculture.
