“…Soil organisms' community is amongst the most important biotic factor in tropical and subtropical ecosystems [10,21,22]. These soil organisms perform a range of ecosystem services including soil structure, soil organic matter transformation, nutrient cycling, biological control etc., [23,24].…”

The use of mulching, compost, and their interaction on organic residue (OR) decomposition rate (k), time of residue decay, primming effect, and soil organisms’ community composition was tested in a 16-year P. pyrifolia field experiment conducted from January 2020 to June 2021. A 2 × 2 factorial design was used with compost and mulching as the two factors within four blocks. OR decomposition was characterized by using litter bags with different mesh, and soil organisms were identified at family level. The half-decay rate (hd), total-decay rate (td), and remaining residue mass (Rm) varied among the organic residue management and mesh-type. The highest values of k and primming effect were found in litter bags with 15 mm2 size containing compost in the plots that received compost. For soil organisms’ abundance and richness, the highest values were found on plot that received both mulching and compost. The observed results suggested that the OR management determined organic matter decomposition, soil organisms’ abundance and richness in an Acrisols of the Southern Brazil. Soil organisms were the main factors contributing to the data variance (e.g., Acaridae, Blattidae, Chrysopidae, Halictophagidae, and Forficulidae).

“…Soil sampling and processing were performed as described by Yang et al 38 The soils were sampled in December 2016; 10 soil cores (0–10 cm depth, 4 cm diameter) were randomly collected across the field at each site. Afterward, the individual soil cores were combined to obtain one composite sample per site, sieved with a 5 mm sieve and homogenized.…”

The intensive use of pesticides and their subsequent distribution to the environment and non-target organisms is of increasing concern. So far, little is known about the occurrence of pesticides in soils of untreated areas—such as ecological refuges—as well as the processes contributing to this unwanted pesticide contamination. In this study, we analyzed the presence and abundance of 46 different pesticides in soils from extensively managed grassland sites, as well as organically and conventionally managed vegetable fields (60 fields in total). Pesticides were found in all soils, including the extensive grassland sites, demonstrating a widespread background contamination of soils with pesticides. The results suggest that after conversion from conventional to organic farming, the organic fields reach pesticide levels as low as those of grassland sites not until 20 years later. Furthermore, the different pesticide composition patterns in grassland sites and organically managed fields facilitated differentiation between long-term persistence of residues and diffuse contamination processes, that is, short-scale redistribution (spray drift) and long-scale dispersion (atmospheric deposition), to offsite contamination.

“…al., (2021) ao avaliarem a comunidade bacteriana em três ecorregiões observaram 41 filos, sendo o mais abundante pertencente a Actinobacteria (33% do total de sequências), seguido por Proteobacteria (25%), Acidobacteria (9,5%), Firmicutes (8%), Chloroflexi (6,5%) , Planctomycetes (4,5%), Verrucomicrobia (3,5%), Bacteroidetes (2,2%), Gemmatimonadetes (1,7%) e Cyanobacteria (1,4%), que juntos representavam > 96% da comunidade bacteriana, porém cada ecorregião apresentou uma dominância diferente de filo. Yang et. al., (2021) estudaram a comunidade microbiana em solos de cultivo de hortaliça orgânica, hortaliça convencional e pastagem e observaram que o sistema de cultivo exerceu efeito significativo sobre a abundância de nematoides, sendo a pastagem a que apresentou maior abundância, seguida pelo cultivo de hortaliça orgânico e convencional.…”

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.
