“…Some bacteria analyzed in this study as potential markers included Nitrospira related to the nitrogen cycle, including nitrification; archaea included Candidatus Nitrososphaera and Candidatus Nitrosotalea, Geobacter associated with biological purification; plant pathogenic bacteria such as Burkholderia, Paraburkholderia, P. brassicacearum, and Rhizobacter; Candidatus Udaeobacter related to antibiotic secretion; and the genus Steroidobacter and Rhodanobacter related to material degradation. This result was similar to that of previous studies, including that by Vestergaard et al [41], in that it comprises a group that could be used to indicate soil health and quality (based on NGS metadata).…”

Soil has multiple functions, including the provision of habitat to organisms, and most biological activities occur in the surface soil. Due to the negative effects of soil erosion, efforts for soil conservation are being made, including the development of a reliable index that can help assess soil quality. In this study, the physical and chemical properties and biological genes from grassland topsoil were analyzed, in order to identify surface soil organism markers that could be used as a soil quality index. Six spots of grassland topsoil were analyzed, one high-quality and five low-quality, based on a web-based soil quality assessment module. Consequently, eukaryotes and prokaryotes with different soil quality ratios were compared and examined. The following bacteria and archaea have the potential to be used in soil quality assessment: circulation of materials including nitrogen, Nitrospira spp., Candidatus Nitrososphaera, and Candidatus Nitrosotalea; biological purification, Geobacter spp.; pathogens, Burkholderia spp., Paraburkholderia spp., Pseudomonas brassicacearum, and Rhizobacter spp.; antibiotic secretion, Candidatus Udaeobacter; and material degradation Steroidobacter spp. and Rhodanobacter spp. This study provides primary data for identifying biological markers for soil quality evaluation. In the future, a wider variety of data need to be accumulated to develop a highly reliable index related to soil quality.

“…The use of organic amendments and strategies related to reducing or eliminating chemical inputs, as well as biological plant protection, are all linked to increased microbial diversity in organic systems [230]. Increase in diversity of microbes enhances metabolic activities and heterogeneous species abundance, implying a steady and functioning redundant population, contributing to potent ecosystem performance based on robust trophic ecosystem [231,232]. Hartmans et al [225] postulated based on dispersion, evenness, and richness, that increased availability of a beneficial substrate such as farmyard manure improved richness by favoring copiotrophic species, whose dominance decreased evenness.…”

Rhizospheric organisms have a unique manner of existence since many factors can influence the shape of the microbiome. As we all know, harnessing the interaction between soil microbes and plants is critical for sustainable agriculture and ecosystems. We can achieve sustainable agricultural practice by incorporating plant-microbiome interaction as a positive technology. The contribution of this interaction has piqued the interest of experts, who plan to do more research using beneficial microorganism in order to accomplish this vision. Plants engage in a wide range of interrelationship with soil microorganism, spanning the entire spectrum of ecological potential which can be mutualistic, commensal, neutral, exploitative, or competitive. Mutualistic microorganism found in plant-associated microbial communities assist their host in a number of ways. Many studies have demonstrated that the soil microbiome may provide significant advantages to the host plant. However, various soil conditions (pH, temperature, oxygen, physics-chemistry and moisture), soil environments (drought, submergence, metal toxicity and salinity), plant types/genotype, and agricultural practices may result in distinct microbial composition and characteristics, as well as its mechanism to promote plant development and defence against all these stressors. In this paper, we provide an in-depth overview of how the above factors are able to affect the soil microbial structure and communities and change above and below ground interactions. Future prospects will also be discussed.

“…Similarly, based on earlier findings, Borrero et al (2004) [163] discusses the importance of diversity as a factor, and comes to the indecisive conclusion that microbial densities, abundance and the total number of microorganisms may not be as important in determining whether a soil performs suppressivity of, or conductivity for, a disease. Additionally, referring to earlier studies, Bertola et al (2021) [159] resolves the importance of microbial diversity as ambiguous in contributing to a more functional and supportive soil. Topalović et al (2020) [90] adds to the debate that suppressivity requires the inclusion of a specific set of microbial community.…”

“…As higher amounts of nitrogen and carbon are mineralised, the amount of extractable phosphorous increases, too. The addition of compost increases soil organic carbon and total N content, the amount of major (N, P, K) and minor elements (Ca, Mg, Na, K), and nutrient availability [112,142,148,[154][155][156][157][158][159][160].…”

“…In their compilation, Bertola et al (2021) [159] emphasise the importance of higher levels of microbial diversity in curbing the severity of pest occurrence and damage to crops, and they draw attention to the idea of "ecological intensification". This concept is based on the idea that a naturally enriched soil microbiome provides a more efficient complexity of soil ecosystem services.…”

The last few years have witnessed the emergence of alternative measures to control plant parasitic nematodes (PPNs). We briefly reviewed the potential of compost and the direct or indirect roles of soil-dwelling organisms against PPNs. We compiled and assessed the most intensively researched factors of suppressivity. Municipal green waste (MGW) was identified and profiled. We found that compost, with or without beneficial microorganisms as biocontrol agents (BCAs) against PPNs, were shown to have mechanisms for the control of plant parasitic nematodes. Compost supports a diverse microbiome, introduces and enhances populations of antagonistic microorganisms, releases nematicidal compounds, increases the tolerance and resistance of plants, and encourages the establishment of a “soil environment” that is unsuitable for PPNs. Our compilation of recent papers reveals that while the scope of research on compost and BCAs is extensive, the role of MGW-based compost (MGWC) in the control of PPNs has been given less attention. We conclude that the most environmentally friendly and long-term, sustainable form of PPN control is to encourage and enhance the soil microbiome. MGW is a valuable resource material produced in significant amounts worldwide. More studies are suggested on the use of MGWC, because it has a considerable potential to create and maintain soil suppressivity against PPNs. To expand knowledge, future research directions shall include trials investigating MGWC, inoculated with BCAs.
