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

Controlled-release potassium sulfate (CPS) and deep banding fertilization are promising strategies for improving crop productivity, but their combined effects on soybean growth remain unclear. In this study, field experiments were performed over two growing seasons (2023-2024) to evaluate how potassium (K) fertilizer types (potassium sulfate and CPS) and fertilization methods (broadcast incorporation and deep banding) influence soil microbial composition, soil enzyme activity, and soybean growth characteristics. The results indicate that deep banding and CPS application consistently increased soybean yield, K use efficiency, and nitrogen use efficiency. Relative to broadcast incorporation, the application methods of deep banding increased soybean yield by 1.1%-2.7% in 2023 and 3.7%-3.8% in 2024, while the application of CPS increased soybean yield by 6.0%-7.7% and 9.6%-9.7% compared with potassium sulfate (PS) application. Additionally, deep banding of CPS increased soil protease, urease, acid phosphatase, and phosphodiesterase activities and improved plant enzyme activities and hormone contents. Microbial analyses showed that CPS combined with the deep banding method (DCPS) enriched several microbial taxa (
