Isolation of highly efficient potassium solubilizing bacteria and their effects on nutrient acquisition and growth promotion in tobacco seedlings.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundTobacco plants are typically high potassium (K)-demanding during growth and development, but the bioavailability of the nutrient in tobacco-growing soils is often limited. AIM AND METHODOLOGY: The present study aimed at screening highly efficient potassium-solubilizing bacteria (KSB) through in vitro experiments, and to grasp their potential role in mineral dissolution for nutrients release. The effects of these bacterial inoculants on soil nutrient bioavailability, macronutrient acquisition, soil bacterial community characteristics, and tobacco seedling biomass were investigated through a greenhouse pot experiment.
resultsThe in vitro experiments showed that the SKL51 (Paenibacillus sp.), SKT41 (Klebsiella oxytoca), and PTG11 (Enterobacter hormaechei) strains were more efficient at solubilizing K than the reference strain RT (Bacillus mucilaginosus). During the 7-day incubation with K-feldspar, the average solubilized potassium by SKL51, SKT41 and PTG11 was 28.8 ± 6.8, 30.1 ± 6.7 and 29.1 ± 1.0 μg mL
conclusionPTG11 and SKL51 had significant effects on soil bacterial community structure, and nutrient mobilization, thereby promoting plant growth in support of ecological benefits and environmental friendliness.
