Organosilanized Hydrophobic Sand for Drought Resilience: Reducing Water Percolation and Enhancing Crop Growth Conditions.
Article in ACS omega, 2025. 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
Recently, increasing frequency and severity of drought events have resulted in significant crop yield reductions worldwide, indicating the critical need for innovative agricultural water management strategies to enhance water use efficiency. Addressing this challenge, we present a novel approach involving the strategic placement of highly hydrophobic sand layers below the subrhizosphere. This method utilizes silica sand modified via a facile, single-step surface treatment, yielding a material with strong hydrophobicity, characterized by a static water contact angle of 133.0 ± 1.0°. Importantly, the modified sand demonstrated stability and retained its hydrophobic properties under simulated adverse agricultural conditions. Systematic investigations of the hydraulic properties revealed that the incorporation of these hydrophobic sand layers substantially controlled the vertical infiltration flux of irrigation water. Specifically, a hydrophobic sand layer with an areal density of 796.5 mg/cm
