Inoculation with plant growth-promoting bacteria mitigates the negative impacts of global warming on nutrient absorption, efficiency, and forage productivity under field conditions.

Inoculation with Azospirillum brasilense and Pseudomonas fluorescens enhances nutrient absorption and soil carbon retention, mitigating warming effects on tropical forage productivity.
- Why it matters: Global warming threatens tropical forage systems by impairing plant nutrition, metabolism, and biomass production, risking reduced forage quality and sustainability.
- What they did: A field experiment with 2°C elevated temperature and inoculation treatments was conducted on Urochloa hybrids over four growth cycles, measuring nutritional, metabolic, and soil carbon parameters.
- The result: Co-inoculation improved nutrient uptake, modulated C-N metabolism, and increased soil carbon fractions, partially offsetting warming-induced declines in forage nutritional resilience and productivity.
