Divergent resource limitations of belowground versus aboveground productivity across grasslands.
Synthesis in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled 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.
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
Water and nutrients are fundamental resources that constrain grassland productivity. Despite significant advances in our understanding of aboveground resource limitations, it remains unresolved whether these insights can be applied to belowground productivity. Here, by combining meta-analyses of 387 nitrogen (N) and 299 phosphorus (P) addition experiments with our long-term experiment in grasslands, we find that, globally, belowground productivity experiences peak N limitation under intermediate precipitation, despite N limitation on aboveground productivity intensifying with increasing precipitation. Moreover, this global pattern of belowground N limitation is mirrored in temporal dynamics. These consistent patterns suggest that belowground N limitation relies strongly and nonlinearly on spatial and temporal water variability. As grassland roots primarily function to capture water, this peak N limitation may reflect a maximal co-limitation of N and water for grassland plants under intermediate water conditions, which is also evidenced by our long-term experiment. Overall, this study highlights the divergent resource limitations of belowground versus aboveground productivity. Future changes in precipitation could significantly modify the patterns of belowground nutrient limitations, ultimately affecting grassland productivity and multifunctionality.
