Soil biota abundance supports ecosystem multifunctionality under carbon farming.
Article in National science review, 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
Organic substrates from plants and animals are crucial for sustainable agriculture, yet their effects on agroecosystem multifunctionality remain underexplored at the global scale. Using a meta-analysis of 8509 field observations, we examined how plant-based carbon inputs (legume cover crops) and animal-based carbon inputs (vermicompost) influence nine ecological functions. Both carbon inputs significantly improved agroecosystem multifunctionality, with legume cover crops increasing it by 17% and vermicompost by 31%. These improvements were concentrated in supporting and provisioning services. Soil biota abundance was strongly linked to multifunctionality and showed more frequent win-win relationships with other functions than species richness. Across agroecosystems, soil biota abundance was primarily associated with local soil properties, followed by climate factors. Our findings highlight soil biota abundance as a community attribute complementary to species richness that contributes to agroecosystem multifunctionality. We further propose site-specific management strategies that align plant- and animal-based carbon inputs with local environmental conditions in global croplands to enhance multifunctionality.
