1 · What the graph read from it

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.

2 · The registry

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

Improving water retention, erosion resistance and nutrients in desert areas is essential for ecological sustainability. This study evaluated the effects of biochar, polyethylene oxide (PEO), and seaweed fertilizer on the properties of desert sandy soil, focusing on water retention, erosion resistance, and soil nutrients. The sandy soil used in the study was taken from the Tengger Desert in Gansu, China, and an orthogonal experimental design was used to select three different proportions of biochar, PEO, and seaweed fertilizer. Compared with the control, applying of these three substances decreased bulk density by 5.8-9.6%, increased porosity by 8.3-14%, and increased water-holding capacity by 2.2-6.7%. The erosion rate decreased by more than 99%, and water-stable aggregates increased by 9.7-37.4%. Soil nutrients showed varying degrees of increase, and seed germination increased by 26.7%. The results of the principal component analysis showed that B6P0.6S2 had the best overall improvement effect. Therefore, a ratio of 6% biochar, 0.6% PEO, and 2% seaweed fertilizer is recommended to improve the properties of sandy desert soils. Overall, biochar, PEO, and seaweed fertilizer can improve the physical properties of desert sandy soil, enhance soil nutrients, and create a stable and suitable environment for plant growth.
