Efecto de los hongos micorrícicos arbusculares en el carbono orgánico del suelo en sistemas agrícolas: una aproximación meta-analítica
This meta-analysis focused on agriculture ecosystems worldwide including both woody and non-woody dominant crop species. We searched on Scopus (last accessed in July 2021) to collect published articles according to our search criteria. Our search terms were: “( TITLE-ABS-KEY ( "soil organic matter" OR "soil organic carbon" OR "particulate organic carbon" OR "mineral associated organic carbon" OR "particulate organic matter" OR "mineral associated organic matter" OR pom OR poc OR maom OR maoc ) AND TITLE-ABS-KEY ( "arbuscular mycorrh*" OR glomal* OR *grsp OR *brsp OR hma ) AND TITLE-ABS-KEY ( crop* OR *cultur* OR farm* OR cultiva* OR agro* ) AND TITLE-ABS-KEY ( pot OR greenhouse OR experiment* OR inoculat* ) )”. We found 118 studies matching these criteria, which were screened according to the selection criteria described below to be included in our compilation. We also included articles cited in the selected papers that could add new information to our review. The articles had to be original research articles performed in agricultural systems; report SOC, particulate organic carbon and/or mineral associated organic carbon and involve both an AM fungi inoculation treatment and a corresponding control without inoculation. We defined the AMF treatment (AMF+) and the control treatment (AMF-) including studies where the application of an AM fungal inoculum represented the AMF+ treatment while the treatment without the application of the inoculum was the corresponding control (AMF-). For that studies that present different crop species or AMF strains, these were included as different trials from the same study. After screening and filtering across a global database, a total of 19 studies were selected, including 62 comparisons (trials) for subsequent analyses (Table 1). From these, we extracted average values with their correspondent variance and sample size (N). Together with this information, auxiliary variables covering plant, microorganisms, soil properties, and experiment-related factors of the studies were also registered.
