Insights into the Maturity of Keratin Byproduct-Based Biofertilizer by UV-Vis, Fourier Transform Infrared Spectroscopy, and Scanning Electron Microscopy Technologies.
Article in ACS omega, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Dog hair keratin byproducts are extremely resistant to degradation and require appropriate waste management technologies. To enhance the degradability of these byproducts, silo cocomposting with food byproducts was performed for 19 weeks. In this study, the physical-chemical analysis (temperature, pH, electrical conductivity, carbon/nitrogen ratios (C/N), germination index, and mineral nutrients) was combined with spectroscopic technologies (ultraviolet-visible (UV-vis), Fourier transform infrared (FTIR) spectroscopy, and scanning electron microscopy (SEM)) as an advanced tool to effectively monitor the maturity of compost, thereby minimizing excessive consumption of time and products. Furthermore, a partial least-squares regression (PLS-R) model was used to predict the final compost quality. As a result, it can be concluded that the compost produced fulfills the norms of applicability of mature compost in agriculture with a C/N ratio below 20 and a germination index of 100%. These results were confirmed by UV-spectroscopy analysis showing an increase in humification and by FTIR depicting the degradation of disulfide bonds in cysteine present in keratin and the degradation of cellulose, hemicellulose, and lignin in food byproducts. This study confirms that a well-managed degradation of keratin byproducts enables them to be upgraded into a valuable product that could be used to improve the fertility of degraded soils and promote plant growth.
