Nitrogen-Rich Soil Doubles Tropical Forest Regrowth, Study Finds
Tropical forests can recover twice as fast after deforestation if their soils contain sufficient nitrogen, according to a new study published January 15, 2026, by the University of Leeds. The research, which tracked forest regrowth in Central America for decades, revealed the critical role of soil nutrients in natural reforestation and its impact on carbon capture.
The study demonstrated that nitrogen plays a decisive role in how quickly trees return after deforestation. Faster regrowth also translates to increased carbon capture from the atmosphere, offering a nature-based strategy for combating climate change, according to Science Daily.
Researchers followed forest plots in Central America for decades, observing the impact of varying soil compositions on regrowth rates. The findings suggest that reforestation strategies should prioritize working with natural soil conditions rather than relying solely on fertilizers.
The research highlights the potential for "smarter reforestation strategies that work with nature," according to the University of Leeds. By understanding and leveraging the natural nutrient composition of soils, reforestation efforts can be significantly accelerated.
The study's findings have implications for global climate change initiatives, as enhanced forest regrowth contributes to increased carbon sequestration. The discovery of nitrogen's crucial role could lead to more effective and sustainable reforestation practices worldwide.
