Selecting suitable predecessors: Ecosystem services from cover crops to reduce tillage and fertilizer.
Article in Scientific reports, 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
Ecosystem services from cover crops can reduce reliance on external inputs and intensive management practices; however, these benefits depend on crop sequence compatibility. The effect of cover crop selection on weed suppression and crop yield was tested by no-till planting winter and summer cash crops into different cover crops that were terminated and used as mulches. Management treatments involving supplemental weeding and fertilizer were also applied to summer cash crops. Overall, this research evaluated 80 combinations of cover crops, cash crops, and management treatments across four site-years in a total of 1280 experimental units. In the absence of supplemental management, cash crops exhibited a 2.6-fold mean difference in weed biomass and a 7.3-fold mean difference in yield when no-till planted into the best- versus worst-performing cover crops, indicating that cover crop selection impacted ecosystem services. Insights from this research can guide cover crop selection and facilitate ecological intensification of agriculture.
