Evaluation of the vegetative properties of biopolymer- and plant fiber-solidified sandy soil.
Article in iScience, 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
A single 45-day indoor planting experiment was conducted to evaluate the vegetative properties of biopolymer- and plant fiber-solidified soil as an eco-friendly material, given that high biopolymer content may hinder plant growth. Using oat as the indicator species, the planting medium consisted of Yellow River silt stabilized with 1.5% xanthan gum and 0.6% jute fiber, prepared at three compaction levels. The study designed and proposed a layered planting structure comprising original residual soil, solidified soil, a grass-seedsowing layer, and a raw soil cover layer. Results showed that this structure achieved a germination rate above 85%, with moderate compaction promoting better growth. Soil temperature remained between 23°C and 28°C, matric suction was stable at approximately 15 kPa, and moisture content uniformly ranged from 10% to 20% across depths. This layered design mitigated surface hardening, enhanced hydrothermal transport, and improved water infiltration through root-formed channels, thereby enabling the functional application of solidified soil in ecological slope protection.
