Soil health improvements under cover crops are associated with enhanced soil content of cytokinins.
Article in Plant biology (Stuttgart, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Cytokinins (CKs) are phytohormones produced by plants and other soil life. including bacteria, fungi, insects, and earthworms. These organisms can release CKs to the soil, which may have positive implications for soil health and plant growth. However, no studies have examined phytohormones as soil health indicators. In custom-designed rhizo-pots that separated rhizosphere and bulk soils, the cover crops tillage radish and cereal rye were used to manipulate soil health parameters: soil pH, soil organic matter, soil active carbon, soil microbial community diversity, and extracellular enzyme activities involved in C, N and P cycling. Data were compared to impacts of cover crops on CKs that were purified from the complex soil and measured with HPLC-HRMS/MS. From soil we detected free base-CKs (trans-zeatin (tZ), isopentenyladenine (iP)), riboside-CKs (RB-CKs), cis-zeatin riboside (cZR), isopentenyladenosine (iPR) and four methylthiolated CKs: 2-methylthio-zeatin (2MeSZ), 2-methylthio-zeatin ribosides (2MeSZR), 2-methylthio-isopentenyladenine (2MeSiP), and 2-methylthio-isopentenyladenine riboside (2MeSiPR). These CK levels were significantly enhanced in cover cropped soil compared to uncultivated soil, and reflect a positive relationship between soil CK profiles and other soil health parameters - notably, between total CK and active C levels and soil microbial community diversity. This is the first detailed soil CK analysis and assessment of its potential use as a novel, reliable, short-term soil health parameter. The increased CK concentrations in cover cropped soils likely reflects the activity levels of soil life (plants, microbes, animals) and provides a rationale to use CKs as tools to evaluate soil health as influenced by agricultural management strategies.
