Effects of planting patterns on physicochemical properties, metabolites and microbial community structure of rhizosphere soil in perennial cultivated grassland.

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
Establishing perennial cultivated grasslands on the Qinghai-Tibet Plateau helps address the seasonal imbalance of forage resources and supports the restoration of degraded grasslands. The most common planting patterns-monocropping and mixed cropping-are well-studied in terms of vegetation structure, productivity, and soil nutrients. Despite their significance, the influence of prolonged planting practices on underground soil microbial communities and metabolites has often been neglected. In this study, two characteristic plants, Festuca sinensis 'Qinghai' and Poa pratensis 'Qinghai', from the area around Qinghai Lake were selected as the experimental subjects by employing 16 S and ITS sequencing methods in conjunction with non-targeted metabolomics analysis. The effects of planting patterns (monocropping and mixed cropping) on rhizosphere soil characteristics, metabolites and microbial community structure were examined. The results showed that compared with monocropping, mixed cropping significantly increased the contents of soil nutrients and key metabolites. In addition, it had a greater impact on fungal diversity than bacterial diversity, particularly in terms of β-diversity. While microbial α-diversity and dominant phyla remained stable, soil fungi were more responsive to changes in soil properties and metabolites. These results show that the new niche differentiation between different species in mixed grassland stimulates the secretion of trehalose and valine, which further affects the fungal community structure and enhances the soil nutrients and ecological functions of degraded grasslands. These findings will guide the restoration of degraded grasslands around Qinghai Lake and the selection of planting strategies to improve local sustainable grassland productivity.
