Effect of acid modification of Biochar derived from spent mushroom substrate on the production of oyster mushroom (Pleurotus ostreatus).
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Spent mushroom substrate (SMS) disposal presents significant environmental challenges in the edible fungi industry. Converting SMS into biochar offers a promising resource utilization approach; however, the original biochar properties limit its effectiveness in mushroom cultivation applications. In this study, SMS biochar was modified by phosphoric acid treatment to form acid-modified mushroom substrates (AMMS), and the influence of acid-modified mushroom substrates on the production of oyster mushroom was evaluated. According to the obtained data, Acid modification significantly increased the surface area and micropore volumes of biochar. Fourier transform infrared spectroscopy (FTIR) analysis revealed the hydrophilicity and adsorption capacity of acid-modified biochar have been enhanced. The highest-performing treatments in AMMS showed 13-16% yield increases compared to unmodified biochar treatments, with harvest time advanced by 2.5 days. The safety assessment confirmed that all treatments with biochar added had no video security risks. In conclusion, phosphoric acid modification of SMS biochar significantly improves its performance as a mushroom cultivation substrate additive. This approach provides an effective strategy for SMS resource utilization and offers technical support for optimizing oyster mushroom cultivation practices.
