Phosphogypsum improves soil and benefits crop growth: An effective measure for utilizing solid waste resources.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The utilization rate of phosphogypsum (PG) is currently low, and prolonged storage poses environmental pollution. Therefore, there is an urgent need to promote resource-efficient utilization. This study investigated the alterations in the characteristics of modified PG artificial soil (MPG-soil) and their influence on buckwheat (Fagopyrum esculentum Moench) growth using hierarchical land reclamation technique (HLRT) and integrated land reclamation technique (ILRT). The results demonstrated that MPG-soil reduced bulk density (3.8-6.9%), enhanced moisture content (up to 22%), and improved enzymatic activity. HLRT achieved superior phosphorus mineralization (7.53 U/g S-NP activity) and increased buckwheat yield by 130.6% over controls. Despite elevated soil salinity, MPG amendments restricted heavy metal accumulation in grains (BCF < 0.3), though Pb levels exceeded national standards due to background contamination. Nutrient dynamics revealed increased phosphorus availability but reduced organic matter, necessitating supplemental fertilization. The Nemerow index confirmed all treatments as "Safe and Clean", while principal component analysis highlighted HLRT's efficacy in balancing soil structure and fertility. Proline accumulation in high-PG treatments indicated adaptive stress responses. MPG-soil effectively contained heavy metal migration, ensuring agricultural product safety. This study assessed the potential of PG for land reclamation, and provided guidelines for its safe utilization in agriculture.
