“…Longterm N additions to a boreal peatland increased P resorption efficiencies in two evergreen shrubs (Wang et al 2014). Nitrogen fertilization in grasslands caused increased P resorption efficiency in some species but not others in Mongolia (Li et al 2012) and in northeastern China (Lu and Han 2010). In the latter study, soil P concentrations did not differ significantly from controls, suggesting that the observed changes in P resorption were not caused by decreased soil P availability following N addition.…”

Previous studies have attempted to link foliar resorption of nitrogen and phosphorus to their. respective availabilities in soil, with mixed results. Based on resource optimization theory, we hypothesized that the foliar resorption of one element could be driven by the availability of another element. We tested various measures of soil N and P as predictors of N and P resorption in six tree species in 18 plots across six stands at the Bartlett Experimental Forest, New Hampshire, USA. Phosphorus resorption efficiency (P < 0.01) and proficiency (P = 0.01) increased with soil N content. to 30 cm depth, suggesting that trees conserve P based on the availability of soil N. Phosphorus resorption also increased with soil P content, which is difficult to explain basdd on single-element limitation, butfollows from the correlation between soil N and soil P. The expected single-element relationships were evident only in the 0 horizon: P resorption was high where resin-available P was low in the Oe (P < 0.01 for efficiency, P < 0.001 for proficiency) and N resorption was high where potential N mineralization in the Oa was low (P < 0.01 for efficiency and 0.11 for proficiency). Since leaf litter is a principal source of N and P to the 0 horizon, low nutrient availability there could be a result rather than a cause of high resorption. The striking effect of soil N content on foliar P resorption is the first evidence of multiple-element control on nutrient resorption to be reported from an unmanipulated ecosystem.

“…C gain efficiency decreased quadratically with increasing P input, which also supported this assumption. The possible explanation for the observed logarithmic relationship is that P absorption proficiency of plant species decreased in response to P addition intensities[32]. Niu et al [33] reported that P addition has no apparent effect on net ecosystem exchange in temperate steppe.…”

Increased nitrogen (N) deposition is common worldwide. Questions of where, how, and if reactive N-input influences soil carbon (C) sequestration in terrestrial ecosystems are of great concern. To explore the potential for soil C sequestration in steppe region under N and phosphorus (P) addition, we conducted a field experiment between 2006 and 2012 in the temperate grasslands of northern China. The experiment examined 6 levels of N (0–56 g N m-2 yr-1), 6 levels of P (0–12.4 g P m-2 yr-1), and a control scenario. Our results showed that addition of both N and P enhanced soil total C storage in grasslands due to significant increases of C input from litter and roots. Compared with control plots, soil organic carbon (SOC) in the 0–100 cm soil layer varied quadratically, from 156.8 to 1352.9 g C m-2 with N addition gradient (R2 = 0.99, P < 0.001); and logarithmically, from 293.6 to 788.6 g C m-2 with P addition gradient (R2 = 0.56, P = 0.087). Soil inorganic carbon (SIC) decreased quadratically with N addition. The net C sequestration on grassland (including plant, roots, SIC, and SOC) increased linearly from -128.6 to 729.0 g C m-2 under N addition (R2 = 0.72, P = 0.023); and increased logarithmically, from 248.5 to 698 g C m-2under P addition (R2 = 0.82, P = 0.014). Our study implies that N addition has complex effects on soil carbon dynamics, and future studies of soil C sequestration on grasslands should include evaluations of both SOC and SIC under various scenarios.

“…2). First, a greater fraction of foliar N and P are resorbed in nutrient-poor soil-plant systems (Aerts 1996, Richardson et al 2005, Silla and Escudero 2006, Li et al 2012, Lu et al 2012. Second, N:P resorption ratios generally increase when the soil is N limited and generally decrease when the soil is P limited (van Heerwaarden et al 2003, Zotz 2004).…”
