Field evaluation of bone biochar for improving maize yield, soil health, and carbon efficiency in arid soils.
Article in BMC plant biology, 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
backgroundthe study aims to evaluate the effectiveness of bone-derived biochar, produced from slaughterhouse waste, as a multifunctional soil amendment within a climate-smart and circular agriculture framework. The central research question explores whether biochar can enhance maize (Zea mays) productivity, improve soil health, and reduce greenhouse gas (GHG) emissions in arid agroecosystems. A two-season field experiment was conducted on loamy sand soil under drip irrigation to assess the impact of biochar applied at 0, 5, 10, and 20 t ha
resultsbiochar significantly improved plant growth, increased biomass by 28%, grain yield by 51%, and enhanced soil quality indicators. Notably, it reduced CO₂ emissions by 24% and N₂O by 15%. The 10 t ha
conclusionsbone-derived biochar offers a sustainable, climate-resilient strategy for improving maize productivity and soil health while contributing to GHG reduction and supporting circular economy goals in arid farming systems.
