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

The study aimed to evaluate the potential of incorporating biochar with poultry manure to address the constant challenges of sandy, loam soils due to poor water retention and low soil fertility, and their influence on the growth and yield of Amaranthus cruentus during the Rabi and Kharif seasons. The combined effect of manures on soil health over different seasons was unexplored, so the current research has been taken up to understand the impact of different treatments on physical, chemical, and microbial dynamics in the Rabi and Kharif seasons. Advanced statistical analysis was used to measure the soil and plant factor variations across seasons. Pre- and post-harvest results showed substantial progress in the soil bulk density, water-holding capacity (WHC), and nutrient retention in KR5 (biochar + poultry manure) treatment, where WHC displayed a strong positive correlation with organic matter (r > 0.82). Even chemical analysis indicated increased soil nitrogen, phosphorus, potassium, and carbon levels. Metagenomic analysis implied microbial diversity and abundance promoting nitrogen fixation and decomposition of organic matter. FTIR and SEM also revealed structural improvements that are beneficial for microbial colonization and nutrient retention. The combination of biochar and poultry manure showed higher growth, increasing plant height by 40 cm and yielding over 550 g/m
