Rooted Soil Shear Apparatus: A low-cost, direct shear apparatus for measuring the influence of plant roots on soil shear strength.
Article in HardwareX, 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
Rooted Soil Shear Apparatus (RSSA) is an open-source laboratory apparatus designed to quantify the effect of plant roots on soil shear strength. Traditional methods used to assess the effect of vegetation on soil strength often rely on expensive proprietary systems and can involve sample disturbance, which may alter the root-soil interactions. This novel apparatus offers both an Arduino-based and a Raspberry Pi solution for data acquisition and control. The device enables laboratory shear testing directly in the same polyvinyl chloride (PVC) pots where the plants grow, eliminating the need to disturb the root-soil structure. Validation experiments demonstrate its effectiveness in capturing shear strength variations in rooted and non-rooted soil samples. By providing an affordable and customizable alternative to conventional shear testing equipment, the RSSA device advances research in geotechnical engineering and soil stabilization.
