Biochar-amended and fertilized conditions influences nitrogen retention and loss dynamics: insights from a sandy loam soil column study.
Article in Scientific reports, 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
Nitrogen (N) leaching from coarse-textured soils poses a significant environmental threat due to high permeability and inherently low nutrient exchange capacity, leading to groundwater degradation and diminished nitrogen use efficiency (NUE). Despite its potential, the depth-resolved and rate-dependent mechanisms governing the interaction between biochar amendments and inorganic N fertilizers remain inadequately characterized. This study evaluated the efficacy of corncob-derived biochar, in synergy with urea fertilizer, on the retention and leaching dynamics of ammonium (NH
