Silicon fertilizer increased potato drought tolerance and reduced soil N
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 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
Silicon (Si) fertilization enhances drought tolerance, but its effectiveness under field conditions and drought intensities remains uncertain. Moreover, the role of Si in regulating greenhouse gas emissions is poorly understood. Therefore, we conducted a field experiment, to assess the effects of Si fertilization on potato yields and on N₂O and CH₄ emissions under drought stress, considering both agronomic and environmental effects. The experiment was conducted on 2 soils (Orthic haplohumod-sand and Typical agrudalf-clay) with drought intensity as main plot (acute drought-AD and severe drought-SD) and Si fertilizers as split plots (amorphous silica-ASi, diatomaceous earth-DE and no-Si addition-control). AD treatments had higher yields than SD, due to higher soil moisture availability. In both soils, Si fertilizers (ASi and DE) produced higher yields associated with enhanced soil moisture and phosphorus content compared to the control. Si fertilizers significantly reduced cumulative N₂O emissions in both soils, with an average reduction of 31% compared to the control, likely due to altered denitrification processes. Our results indicate that, at field scale, Si fertilization has the potential to be a sustainable solution for maintaining potato production while reducing agricultural N
