ABSTRACT:     Study aimed to (i) assess the impact of analog agroforestry (agrofor) on arbuscular mycorrhizal fungi (AMF), easily extractable glomalin-related soil protein (EE-GRSP), soil organic matter (SOM), and aggregate stability compared with a pasture system and (ii) investigate the chemical, physical and OM properties that explain the differences in soil microbiology between sites. The study was conducted in an agrofor and pasture area. Soil samples were collected in the dry season. A total of 12 AMF taxa were identified. Mean richness was positively correlated with soil pH, Mg2+, sum of bases (SB) and moisture. Mean richness and diversity were higher in the analog agroforestry site. Pasture soil had higher EE-GRSP content and spore abundance, variables that were found to be positively correlated with soil temperature, P, K+, and H + Al. EE-GRSP also showed a positive correlation with total organic carbon. Aggregate stability was greater in soil under analog agroforest than pasture. SOM properties did not differ between sites. It is concluded that agrofor changes the evaluated soil physical and microbiological attributes, and the microbiological attributes are influenced by the pH, Mg+2, K+, SB, P, H+Al, soil moisture and TOC.

RESUMO:     O estudo objetivou avaliar o impacto de um sistema agroflorestal regenerativo análogo (SAFRA) na comunidade de fungos micorrízicos arbusculares (FMAs), na proteína do solo relacionada à glomalina - facilmente extraível (PSRG-FE), na matéria orgânica (MO) e na estabilidade de agregados comparado a uma área de pastagem. Além disso, avaliar as propriedades químicas, físicas e da MO que explicam a variação dos atributos microbiológicos do solo em tais áreas. O estudo foi conduzido em uma área de SAFRA e de pastagem. As amostras de solo foram coletadas na estação seca. Foram identificados 12 taxas de FMAs. A riqueza média (RM), correlacionou-se positivamente com o pH, Mg2+, soma de bases (SB) e umidade do solo. Tanto a riqueza média quanto a diversidade foram maiores no SAFRA. Na pastagem, foram maiores a abundância de esporos (AE) e PSRG-FE, sendo que ambas as variáveis se correlacionaram positivamente com a temperatura do solo, P, K+ e H+Al. A PSRG-FE também se correlacionou positivamente com o carbono orgânico total. A estabilidade de agregados foi maior no SAFRA, e os atributos da MO não variaram entre as áreas. Conclui-se que o SAFRA altera os atributos físicos e microbiológicos avaliados, e os atributos microbiológicos são influenciados pelo pH, Mg+2, K+, SB, P, H+Al, umidade do solo e COT.
