Changes in plant nutrient status following combined elevated [CO₂] and canopy warming in winter wheat.

ABSTRACT: Projected global climate change is a potential threat to nutrient utilization in agroecosystems. However, the combined effects of elevated [CO₂] and canopy warming on plant nutrient concentrations and translocations are not well understood. Here we conducted an open-air field experiment to investigate the impact of factorial elevated [CO₂] (up to 500 μmol mol^-1) and canopy air warming (+2°C) on nutrient (N, P, and K) status during the wheat growing season in a winter wheat field. Compared to ambient conditions, soil nutrient status was generally unchanged under elevated [CO₂] and canopy warming. In contrast, elevated [CO₂] decreased K concentrations by 11.0% and 11.5% in plant shoot and root, respectively, but had no impact on N or P c
