Biochar Impacts on Soil Silicon Dissolution Kinetics and their Interaction Mechanisms.
Article in Scientific reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
Effects of biochars on soil silicon dissolution kinetics remain unaddressed. Si-rich rice husk (RH) and rice straw (RS), and Si-deficient wood sawdust (WB) and orange peel (OP) were applied to prepare biochars at 300-700 °C. The silicon dissolution of Si-rich biochars was relatively high in comparison with Si-deficient biochars, and increased with the pyrolysis temperature. The mechanism of silicon release is suggested to be controlled by a protective carbon-silicon interaction, as accompanied by carbon release. After mixing with soil, the addition of Si-rich biochar leads up to 72.7-121% improvement in silicon dissolution in a high-silicon soil (HSS) compared to 147-243% improvement in a low-silicon soil (LSS). The total cumulative amount of silicon dissolved decreased compared to the theoretical value due to the adsorption of silicic acid by the biochar. The addition of WB700 or OP700 as Si-deficient biochars leads to a cumulative Si dissolution decrease of 15.7 and 12.1%, respectively. The adsorption of silicic acid in the biochar and the protection of soil dissolved Fe make biochar a reservoir of soil silicon. Thus, Si-rich biochar could serve as a source of Si with slow release, while Si-deficient biochar could serve as an extra Si sink in agricultural paddy soil.
