WHAT THE EVIDENCE SAYS
An Acinetobacter strain increased elemental sulfur oxidation by 3.7–29.4% in tested sodic soils and reduced sodium adsorption ratio by 32–41%. With sulfur, rice and wheat yields were 4.8–19.3% higher than sulfur alone under lysimeter conditions.
WHY IT MATTERS / OUR READ
Linked soil chemistry and yield responses are promising for difficult soils, but land managers should await field efficacy and environmental safety tests before applying a live microbial inoculant.
CAVEATS / UNCERTAINTY
This was laboratory and lysimeter work, not replicated farm-field validation; the authors request broader phenotypic and genomic biosafety assessment.
