“…N fertilization significantly increased N concentrations in wheat (Fig. 1 c, d), which was observed in other studies (Ruohomaki et al, 1996;Tomassen et al, 2003;Esmeijer-Liu et al, 2009). At harvest, the grain N and P contents were higher, indicated that N and P in other parts of wheat transferred to the grain.…”

Nitrogen fertilizer is the most commonly fertilizer for increasing grain yield of wheat, but its effects on wheat carbon (C), nitrogen (N) and phosphorus (P) availability are not clear yet. This field experiment was conducted to evaluate the C, N and P stoichiometry characteristics of winter wheat and soil and their relationship during the anthesis and harvest stages under nitrogen fertilization (0, 180, 360 kg ha -1 ) in Northwest China. We found that N fertilization could increase N contents, C: P and N: P ratios and decrease P contents, C: N ratio in wheat. During anthesis, the highest N and P contents were found in the flag leaf and culm, respectively and at harvest, N and P contents were higher in the grain. N and P contents in all tissues of wheat were related, and more importantly, a significant relationship with the soil N and P contents was found, these results could help us understand the nutritional balance regulation in wheat under nitrogen fertilization.

“…Under ambient water conditions, decreased C:Ng and C:Ns in response to N addition were in line with results from other studies (Esmeijer- Liu et al 2009;Novotny et al 2007). Under elevated water conditions, however, N addition showed no eVect on C:Ng and C:Ns.…”

“…They can also change in response to global change factors, such as elevated CO 2 concentration (Billings et al 2003), increased N deposition (Esmeijer-Liu et al 2009), decreased biodiversity (Knops et al 2001) and interactions among these factors (Henry et al 2005;Knops et al 2007;Novotny et al 2007). Concurrently, potentially altered precipitation regimes resulting from global climate change may exert strong controls on community composition and ecosystem function of arid and semi-arid areas (Huxman et al 2004;Suttle et al 2007;Bai et al 2008;Gerten et al 2008).…”

Nitrogen and water availability interact to affect leaf stoichiometry in a semi-arid grassland

The effects of global change factors on the stoichiometric composition of green and senesced plant tissues are critical determinants of ecosystem feedbacks to anthropogenic-driven global change. So far, little is known about species stoichiometric responses to these changes. We conducted a manipulative field experiment with nitrogen (N; 17.5 g m(-2) year(-1)) and water addition (180 mm per growing season) in a temperate steppe of northern China that is potentially highly vulnerable to global change. A unique and important outcome of our study is that water availability modulated plant nutritional and stoichiometric responses to increased N availability. N addition significantly reduced C:N ratios and increased N:P ratios but only under ambient water conditions. Under increased water supply, N addition had no effect on C:N ratios in green and senesced leaves and N:P ratios in senesced leaves, and significantly decreased C:P ratios in both green and senesced leaves and N:P ratios in green leaves. Stoichiometric ratios varied greatly among species. Our results suggest that N and water addition and species identity can affect stoichiometric ratios of both green and senesced tissues through direct and interactive means. Our findings highlight the importance of water availability in modulating stoichiometric responses of plants to potentially increased N availability in semi-arid grasslands.

“…Conversely, plant species diversity generally declines in response to N enrichment (Clark et al 2007). Furthermore, N enrichment will potentially influence plant biomass stoichiometric composition (Esmeijer-Liu et al 2009;Novotny et al 2007), which exerts strong controls on plant growth rate (Niklas et al 2005), ecosystem nutrient use efficiency (Vitousek 1982), litter decomposition (Güsewell and Gessner 2009), herbivory (Hall et al 2007), and several other ecosystem processes. Nevertheless, we still know little about plant stoichiometric responses to the increased N availability.…”

“…Most previous studies on the responses of plant tissue chemistry and stoichiometry to N enrichment focused on the changes of C and N concentration and C:N ratios (Esmeijer- Liu et al 2009;Knops et al 2007). This may be due to the suggestion that productivity in most ecosystems is limited by N availability (LeBauer and Treseder 2008).…”

Nitrogen fertilization and fire act independently on foliar stoichiometry in a temperate steppe

Nitrogen (N) fertilization, as a grassland management strategy, has been widely used to improve forage quality and increase the productivity of grasslands degraded by overstocking. It is widely accepted that N addition will alter ecosystem structure and function, and that these effects may be altered by natural disturbances, such as fire. We examined the effects of annual burning and N fertilization (17.5 g N m −2 year −1 , at a surplus rate in order to simulate agriculture treatment) on foliar chemistry and stoichiometric ratios of eight dominant species (Leymus chinensis, Stipa grandis, Cleistogenes squarrosa, Potentilla bifurca, Thalictrum squarrosum, Artemisia frigida, Kochia prostrata and Caragana microphylla) in a temperate steppe in northern China. After 3 years of treatments, annual burning significantly increased soil extractable phosphorus (P) concentration but showed no effects on soil inorganic N concentration, whereas N fertilization caused a significant increase in inorganic N concentration but not of extractable P. Species differed substantially with respect to all nutritional and stoichiometric variables. Both annual burning and N fertilization caused significant increases in foliar N and P concentrations and thus decreases in carbon (C):N and C:P ratios. While annual burning showed no effects on N:P ratios, N fertilization produced higher N: P ratios. However, species responded idiosyncratically to both fire and N fertilization in terms of foliar N concentration, C:N and N:P ratio. In addition, there was no interaction between fire and N fertilization that affected all variables. This study suggests that both annual burning and N fertilization have direct impacts on plant elemental composition and that fire-and N addition-induced changes of community composition may have important consequences for plant-mediated biogeochemical cycling pathways in temperate steppe ecosystem.
