1 · What the graph read from 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.

2 · The registry

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

Introduction: Straw return is recognized as an effective practice for improving soil organic matter. However, in the black soil regions of China, limited information is available on how the individual or combined application of crop straw and straw-derived biochar influences soil carbon-converting enzymes and the soil Methods: This study conducted three consecutive growing-season field experiments in a typical black-soil zone using a soybean-corn rotation system. Four straw return treatments were established based on equal carbon input (2,500 kg·hm Results: The results indicated that compared to T0, the four treatments had no significant effect on soil labile organic carbon (LOC) but significantly effect soil organic carbon (OC), dissolved organic carbon (DOC), and microbial biomass carbon (MBC) ( Discussion: Overall, the response of carbon mineralization to straw and biochar application was primarily driven by the content of soil carbon fractions, which were regulated by enzyme activity. This study provides a scientific basis for enhancing the carbon sequestration potential of black soils in China.
