Thin on the right so far
None of the 19 outlets with a published leaning rating that ran this story are rated right.
This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.
Scientists are developing soybeans with enhanced root systems to improve their resilience to climate change and increase their capacity to store carbon in the soil. The Salk Institute for Biological Studies is conducting research to determine if these deeper roots can serve as a method for carbon removal. This work is supported by an $18 million grant from the Bezos Earth Fund, which will facilitate field testing of the plants' resistance to drought and other climate stressors, their carbon storage potential, and methods for large-scale adoption by farmers.
The research involves identifying and editing plant genes to promote root growth. Scientists have identified 347 genes associated with carbon storage and root development. By editing the DNA of soybean plants, they have created varieties with roots that penetrate deeper into the soil. Researchers hypothesize that these longer and larger root systems could access water in drier conditions, store carbon further underground where it is less likely to be released, and potentially absorb more nitrogen and fertilizer runoff.
Based on earlier laboratory findings, researchers estimate that one hectare of soybeans with deeper and larger roots could store an additional metric ton of carbon dioxide annually. The duration for which this carbon remains stored depends on root depth and soil conditions. Field trials are underway at multiple sites, including the University of Illinois Urbana-Champaign, to gather data on carbon storage, crop yield, and plant performance under various conditions, such as controlled drought scenarios.
Disagreement on initial findings
Initial results from field tests are expected this autumn, according to Wolfgang Busch, director of the Salk Institute’s Harnessing Plants Initiative. However, the Washington Top News report notes that scientists still need to demonstrate how much additional carbon these roots can store under actual farming conditions, the longevity of underground carbon storage, and whether crop yields can be maintained.
Omissions
None of the left- or centre-rated reports mention the potential for deeper-rooted crops to absorb more nitrogen and fertilizer runoff, a detail present in the full report from Washington Top News.

How each side covered it
Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.
Left
8 rated outlets
- Left-rated reports led on the potential for deeper-rooted soybeans to withstand climate extremes and store more carbon. These reports highlighted the broader context of carbon removal efforts, mentioning direct air capture, changes to ocean chemistry, and reforestation as other methods scientists are exploring. The digests in this section carried details about the Salk Institute's research and the $18 million grant from the Bezos Earth Fund.
Centre
11 rated outlets
- Centre-rated reports focused on the development of soybeans with deeper root systems as a means to withstand climate change effects and store more carbon. These reports included details about the Salk Institute's research process, such as identifying 347 genes related to carbon storage and root growth, and editing plant DNA. The $18 million grant from the Bezos Earth Fund was also a prominent detail across these reports.

Questions about this coverage
- How did the left and right cover Soybean roots engineered to boost carbon storage?
- Of the 19 outlets on this story carrying a published leaning rating, 42% are rated left, 58% are rated centre, 0% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 20. The sections above set out what each side emphasised, in its own terms.
- Is Soybean roots engineered to boost carbon storage left or right?
- Neither side dominates it. Of the 19 rated outlets on this story, 42% are rated left, 58% are rated centre, 0% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
- Is the coverage of Soybean roots engineered to boost carbon storage biased?
- Soybean roots engineered to boost carbon storage is one event reported by 20 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
- Which side is not reporting Soybean roots engineered to boost carbon storage?
- When we first saw this story, outlets rated right had barely covered it. Coverage accretes for hours after an event, so that is where to look rather than a verdict — the split above is the current count, and it is the one to read.
- Which outlets covered Soybean roots engineered to boost carbon storage?
- 20 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
- How are scientists developing soybeans to withstand climate change?
- Scientists are engineering soybeans to grow deeper root systems. This allows the plants to access water further down in the soil during droughts and helps them store more carbon underground. They are identifying and editing specific genes related to root growth and carbon storage to achieve this.
- What is the role of the Bezos Earth Fund in this research?
- The Bezos Earth Fund has provided an $18 million grant to the Salk Institute researchers. This funding is crucial for conducting field testing to assess the plants' resilience to climate stressors, their carbon storage capabilities, and the feasibility of scaling up their adoption in agriculture.
- How much additional carbon could these soybeans store?
- Researchers estimate that one hectare of soybeans with deeper-rooted systems could store an additional metric ton of carbon dioxide per year. This potential contribution to carbon removal is a key focus of the ongoing field trials.
