Soil acidity remediation in sub-Saharan Africa requires targeted investments.
Article in Nature food, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Acid soils are widespread across sub-Saharan Africa. Agricultural lime can be used to alleviate production constraints associated with soil acidity, but lime is not widely available in the region, and it is unclear if applying it would be profitable. Using lime requirement models and crop yield responses to soil acidity modelled as plateau-linear decay functions, we estimated the profitability of acid soil remediation through liming. Crop yield loss to soil acidity occurs on 32.7 Mha, or 23% of sub-Saharan Africa's cropland. The burden of acid soils is US$6.0 billion (6% of the current production value), and 75% of that could be profitably alleviated. Under prevailing conditions, liming would be profitable in the year of application on 6.2 Mha (with an average profitability of US$278 ha
