“…Other work done on willows showed that early microbial community composition could predict the potential of the trees to decontaminate soil or to survive (Bell et al 2014;Yergeau et al 2015). Navarro-Noya et al (2022) showed that the complexity of microbial structure and diversity increases with maize development, and that the effect of agricultural practices on the soil microbiome was more evident at the early stages, which could explain why early microbial indicators performed better. This is encouraging for future work, as the ultimate goal of this type of predictive modeling is to have a tool that could be used to guide management strategies for farmers.…”

Previous studies have shown that it is possible to accurately predict wheat grain quality and yields using microbial indicators. However, it is uncertain what the best timing for sampling is. For optimal usefulness of this modeling approach, microbial indicators from samples taken early in the season should have the best predictive power. Here, we sampled a field every two weeks across a single growing season and measured a wide array of microbial parameters (amplicon sequencing, abundance of N-cycle related functional genes, and microbial carbon usage) to find the moment when the microbial predictive power for wheat grain baking quality is highest. We found that the highest predictive power for wheat grain quality was for microbial data derived from samples taken early in the season (May-June) which coincides roughly with the seedling and tillering growth stages, that are important for wheat N nutrition. Our models based on LASSO regression also highlighted a set of microbial parameters highly coherent with our previous surveys, including alpha- and beta-diversity indices and N-cycle genes. Taken together, our results suggest that measuring microbial parameters early in the wheat growing season could help farmers better predict wheat grain quality.

“…Results for SOM parameters (Table 2) such as TOC and TN were not significantly influenced in the three years of CONS management, consistent with the data reported by Muscolo et al [47] while Rakesh et al [48] in a 4-year-long experiment found a significant TOC improvement compared to conventionally managed soils. Microbial biomass and soil enzymatic activities were found to be more reliable factors to depict the soil evolution both in short periods [23,49] and long periods [50]. The significant increase in β-glucosidase activity in CONS indicated an improvement in carbon cycle and the significant differences between the managements suggest an important role of cover crops in the soil evolution under conservative management.…”

Conservation Agriculture includes practices focused on the conservation and the restoration of main soil features, such as organic carbon content, structure, and biological diversity and activity. Our study was conducted in three farms in North-Eastern Italy in pairs of closely located fields to compare conservation agriculture (no tillage, cover cropping) with conventional agriculture. Differences in terms of soil enzymatic activity, such as FDA and β-glucosidase through spectrophotometric analyses, microbial biomass carbon and nitrogen contents, total organic carbon, and nitrogen contents with CNS Elemental Analyzer and soil arthropod community via the QBS-ar index were investigated. Enzymatic activities resulted to be readily and positively affected by conservation agriculture whereas total and microbial carbon, nitrogen contents, and microarthropod community seemed to be more dependent on the time factor. The responses to conservation agriculture differed between the three farms, pointing out that differences in soil features may drive the effectiveness of conservation management. N stock, maybe dependent on previous soil management, might be the key characteristic able to influence soil evolution in the studied conditions. The present results could be helpful to predict soil reaction to sustainable agriculture in short periods.

Solos agrícolas tendem a perder sua qualidade conforme o seu uso, manejo e dos cultivos, principalmente em relação a comunidade de microrganismos presente no solo. Para levantar informações sobre a alteração da biodiversidade microbiana do solo devido ao cultivo agrícola objetivou-se com esta revisão bibliográfica utilizar o banco de dados Scopus para verificar a literatura existente sobre o tema proposto e se há alteração conforme seu manejo. A busca foi realizada nos artigos contidos no banco de dados buscando no título, resumo e palavras chaves utilizando quatro termos indexados: biodiversity, microbial, soil e agricultural. Foram encontrados 891 artigos e estes foram utilizados para a análise bibliométrica, para a escrita deste artigo utilizou-se dois filtros: para os artigos de acesso aberto e dos anos de 2017 a 2022, selecionando então 216 artigos para serem estudados nesta revisão. Com o auxílio do programa estatístico R versão 4.2.0 foi realizada a análise bibliométrica com o pacote bibliometrix. Na análise bibliométrica foi possível identificar que os artigos relacionados ao tema começaram a ser publicados no ano de 1992 com poucas publicações, ultrapassando a marca de 25 artigos publicados por ano apenas em 2008, passando de 75 artigos publicados ao ano apenas em 2017 e desde então aumentou o interesse de publicação na área. Também foi possível observar que o país que mais publica com o tema é os Estados Unidos e a palavra mais citada nos títulos dos artigos é o microrganismo bactéria. Esta revisão revela que a mudança de um sistema nativo para cultivo agrícola, bem como a espécie cultivada, a biodiversidade microbiana do solo se altera.
