“…Generally, a large number of field and laboratory studies have examined the effect of N addition on Rs by periodic measurements of the respiratory processes. Measurements of Rs after N addition varied across studies, and the majority of sample interval from one week to one month after N addition [18][19][20]. However, an examination of how sampling interval affects Rs and investigation into the duration of this effect after N addition received little attention.…”

“…Greater photosynthesis resulting from N addition led to significant increases in fine-root, coarse-root, leaf and stem biomass (Table 2). Therefore, the N-induced enhancement of R A was due to increased photosynthesis, which might have supplied more carbon photosynthate for root and soil microbial activities (Carreiro et al 2000;Xu and Wan 2008;Yan et al 2010;Gao et al 2014). The reduction in R H after fertilization presumably resulted from the additional N retarding the decomposition of soil organic material by altering soil microbial communities (Allison et al 2008) or limiting soil Values are mean ± SD (n = 4).…”

“…Phillips and Fahey (2007) presented evidence that decreased SR was due to the reduction of R H in fertilized forest soils, while Olsson et al (2005) attributed it to a decrease in R A . Addition of N influences photosynthate supply (Xu and Wan 2008;Gao et al 2014). Thus the conflicting responses of SR after addition of N could derive from varying levels of photosynthate supply for R A .…”
