Canopy and understory nitrogen addition have different effects on fine root dynamics in a temperate forest: implications for soil carbon storage

Abstract: Elucidating the effects of atmospheric nitrogen (N) deposition on fine root dynamics and the potential underlying mechanisms is required to understand the changes in belowground and aboveground carbon storage. However, research on these effects in forests has mostly involved direct understory addition of N and has ignored canopy interception and processing of N.Here, we conducted a field experiment comparing the effects of canopy addition of N (CAN) with those of understory addition of N (UAN) at three N-addit… Show more

“…CO 2 emissions are renowned for their influence on environmental deterioration in the form of pollution, despite the fact that various other forms of emissions also exist. Globalization (GLO), economic growth (GDP), renewable energy consumption (REC), technological innovation (TI), financial development (FD), and human capital (HC) have all been linked with CO 2 emissions (Ahmed and Le 2021 ; Alola et al 2021 ; Bekun et al 2021 ; Li et al 2021a , b , c ; Li, Zhang, Zhang, Wu, and Zhu et al 2021c ; Lin et al 2021 ; Miao et al 2018 ; Ozturk and Acaravci 2016 ). In this regard, it is crucial to acknowledge the climate change problem; otherwise, the associated risks and hazards, which are projected to rise in future years, will have devastating implications for human health and safety.…”

“…Mean DBH and mean tree height were 26.6 cm and 21.6 m, respectively, on July 2012 (Zhang et al 2015). Soil total C, total N, pH, and available P content (extracted with 0.025 mol/L HCl and 0.03 mol/L NH 4 F, Bray-1 method) were 32.6 0.6 g kg 1 , 2.3 0.2 g kg 1 , 4.29 0.09, and 7.01 0.58 mg kg 1 , respectively (Li et al 2021).…”

“…As a result, the oxidation of ammonia nitrogen accelerates and much amount of nitrate nitrogen is lost from the soil (Yin, 2016). However, higher nitrogen deposition will greatly enhance the amount of active nitrogen, leading to excessive nitrogen in the soil (Li et al, 2021;Li et al, 2021b;Li et al, 2021c). Consequently, the soil nitrogen cycle is affected.…”
