Abstract. Nutrient resorption in plants influences nutrient availability and cycling and is a key process in biogeochemical models. Improved estimates of resorption parameters are needed for predicting long-term primary productivity and for improving such models. Currently, most models assume a value of 50% resorption for nitrogen (N) and phosphorus (P) and lack resorption data for other nutrients and for specific vegetation types. We provide global estimates of resorption efficiencies and nutrient concentrations for carbon (C), N, and P and the first global-scale estimates for essential nutrients such as potassium (K), calcium (Ca), and magnesium (Mg). We also examine leaf mass loss during senescence (LML) globally and for different plant types, thus defining a mass loss correction factor (MLCF) needed to quantify unbiased resorption values. We used a global meta-analysis of 86 studies and ;1000 data points across climates for green and senesced leaves in six plant types: ferns, forbs, graminoids, conifers, and evergreen and deciduous woody angiosperms. In general, N and P resorption differed significantly from the commonly used global value of 50% (62.1%, 64.9%, respectively; P , 0.05). Ca, C, and Mg showed lower average resorptions of 10.9%, 23.2%, and 28.6%, respectively, while K had the highest resorption, at 70.1%. We also found that resorption of all nutrients except Ca depended on leaf nutrient-status; globally, C, N, P, K, and Mg showed a decrease in resorption with increased nutrient status. On average, global leaf mass loss was 24.2%. Overall, our resorption data differ substantially from commonly assumed values and should help improve ecological theory and biogeochemical and landsurface models.

“…In our study, soil N and P (%) contents generally increased with increasing altitude. Kilic et al (2010) also reported that total N, available P, soil water content, and soil organic matter increased along with the altitudinal gradient. Other researchers found that there were positive correlation coefficients between soil and plant nutrient levels (Powers, 1984;Johnson et al, 1987).…”

“…The reason for this may be due to the increase in the concentration of N and P in the soil. Kilic et al (2010) reported that resorption was affected by the altitude gradient, and, as a result, resorption efficiency and proficiency altered depending on altitude. Killingbeck (1996) and Vergutz et al (2012) argued that water availability, timing of abscission, leaf nutrient status, or shade could cause the variations between resorption efficiencies.…”

“…Diminution of LMA also brings potential short-term benefits of lower leaf structure costs per area, and lower maintenance costs (i.e. respiration rates per area) (Lusk et al, 2008;Kilic et al, 2010). SLA is the rate of leaf area and leaf dry matter, and it is one of the most significant leaf characteristics (Liu et al, 2008;Ozbucak et al, 2011).…”

Phosphorus (P), nitrogen (N), carbon (C), and sulfur (S) contents of the leaves and specific leaf area (SLA), leaf mass per area (LMA), and N and P resorption were researched in Vaccinium arctostaphylos L. and Vaccinium myrtillus L., economically important for the East Black Sea region of Turkey. The leaves samples were collected from Solaklı Valley in Trabzon at 60 to 1800 m for V. arctostaphylos L. and 2100 to 2300 m for V. myrtillus L. The N, C, and S contents were determined by Dumas method and P concentration by the stannous chloride method. Nutrient contents, SLA, and LMA in leaves and N, P, organic matter, and pH in soil were measured. The foliar N, P, C, and S contents of the plants depending on the altitude gradient were statistically significant. N and S contents were significantly important during the growing season for both species. There were significant differences in terms of N and P proficiency for both species. Resorption values of V. myrtillus L. were found to be within the normal limits and the resorption efficiency values increased in parallel with the altitude changes. N resorption levels of V. arctostaphylos at lower (60 m) and higher (1800 m) altitudes were below the declared limits. It was also seen that while N proficiency showed significant increase, P proficiency decreased depending on the altitude. Both N and P proficiency for V. myrtillus decreased with the altitude increase.

“…When these nutrient concentrations vary among sites in inter-or intraspecific comparisons, it has been interpreted as a consequence of soil nutrient availability (Shaver and Melillo 1984; Lajtha and Klein 1988;Vitousek et al 1995;Covelo et al 2008). However, slight variations in foliar nutrient concentrations between Quercus species have been reported when they grow together at the same site (Aponte et al 2011;Covelo et al 2008;Kilic et al 2010;Knops and Koenig 1997;Wu et al 2012). In the case of the species studied here, the N and P concentrations and N/P ratio of green leaves did not differ between the two Quercus species, while P availability varied among soils under these species.…”

Foliar nutrient resorption constrains soil nutrient transformations under two native oak species in a temperate deciduous forest in Mexico

Foliar nutrient resorption (FNR) is a key process in the dynamics of nutrients in a forest ecosystem. Along with other factors, FNR regulates the chemical composition of the forest floor and, consequently, the rates of organic matter decomposition and soil nutrient availability. The main objective of the present study was to examine the effect of FNR of two deciduous oak species (Quercus castanea and Q. deserticola) in the litter and soil nutrient dynamics, in addition to analyze whether the interaction between two species was positive (synergistic) or negative (antagonistic) through the mixed litter from two species. For this purpose, the nutrient concentration of green leaves, litterfall, litter and soil was measured, as well as soil microbial activity. These measurements were taken in isolated stands with the presence of one of the oak species and stands with the two oak species mixed. Quercus deserticola, with lower FNR, produced litter with a higher N concentration, which apparently enhancing microbial activity in the forest floor litter and increased nutrient transformations and soil fertility. In contrast, Q. castanea has a higher FNR and produced litter with a lower nutrient concentration. The microbial soil community associated with Q. castanea must therefore invest more energy in metabolic processes at the expense of biomass growth. However, forest floor nutrient transformations were more intense and soil fertility increased in areas where both species intermix; in this case, the latter species received the rich-nutrient litterfall of Q. deserticola. These results suggest a strong footprint of species traits on microbial activities and soil nutrient transformations.
