Elevated CO₂ and Nitrogen Supply Boost N Use Efficiency and Wheat (T. aestivum cv. Yunmai) Growth and Differentiate Soil Microbial Communities Related to Ammonia Oxidization.

ABSTRACT: Elevated CO₂ levels (eCO₂) pose challenges to wheat (Triticum aestivum L.) growth, potentially leading to a decline in quality and productivity. This study addresses the effects of two ambient CO₂ concentrations (aCO₂, daytime/nighttime = 410/450 ± 30 ppm and eCO₂, 550/600 ± 30 ppm) and two nitrogen (N) supplements (without N supply-N0 and with 100 mg N supply as urea per kg soil-N100) on wheat (T. aestivum cv. Yunmai) growth, N accumulation, and soil microbial communities related to ammonia oxidization. The data showed that the N supply effectively mitigated the negative impacts of eCO₂ on wheat growth by reducing intercellular CO₂ concentrations while enhancing photosynthesis parameters.
