Study Reveals Drop in Fertilizing Effect of Excess CO2 on Vegetation Worldwide
Plants tend to remove CO
2 from the air when they absorb it for their growth. Thus, CO
2 gets sequestered in their roots, trunk, or branches.
Science demonstrates that this fertilizing impact of CO
2 is reducing globally, as per the study co-directed by Professor Josep Peñuelas of the CSIC at CREAF and Professor Yongguan Zhang of the University of Nanjin, with the contribution of CREAF scientists Jordi Sardans and Marcos Fernández.
The study performed by an international team suggests that the decrease has reached 50% progressively from 1982 mainly due to two factors: the availability of nutrients and water.
