Microbial community in alfalfa rhizosphere in response to rhizobial inoculation under increased concentrations of potentially toxic elements.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: The rhizosphere is a very active region containing a large number of microorganisms involved in complex biological and ecological processes. The microorganisms can improve the soil conditions, promote plant growth, and alleviate stress in plants under heavy metal contamination. Rhizobial bacterium ( Methods: This study aimed to evaluate the effects of rhizobial inoculation on alfalfa growth and rhizosphere microbiological properties in soils with increased nickel (Ni) concentrations during 2 years and across seasons. Two locations with different heavy metal concentrations, lower and higher, mainly Ni concentrations, but also lead (Pb) and chromium (Cr); six different rhizobial inoculants; and three different sampling time points were tested. The abundance of different groups of culturable bacteria (total number of microorganisms, fungi, actinomycetes, oligonitrophiles, Results and discussion: The inoculation in some treatments significantly increased alfalfa yield in particular cuts, depending on the location ( Conclusion: The results show the potential of inoculation with particular rhizobia in the improvement of alfalfa yield in Ni-contaminated soils and overall microbiological properties and indicate the complexity of the interactions of multiple factors in the environment.
