“…Our site has a total N flux (including DON and DIN) of 43 kg ha -1 y -1 in throughfall plus stemflow. It demonstrates that the throughfall plus stemflow is an important pathway for N transfer in the Okinawan subtropical forest, although litterfall is the major pathway for nutrient transfer [38].…”

-Precipitation partitioning into throughfall and stemflow and related hydrochemical fluxes were examined during a 3 y period from January 1998 to December 2000 in a subtropical evergreen broad-leaved forest on Okinawa Island, Japan. Monthly water samples were collected to determine the concentrations and associated fluxes of bioelements. The mean annual precipitation during the study period was 3325 mm. Typhoons played a central role in the hydrology of the study forest with 11 typhoons contributing 29.1% of the total rainfall over the 3 y period. Throughfall and stemflow contributed 53.9% and 30.9% of the annual rainfall, respectively, implying a rainfall interception of 15.2%. The very high fraction of stemflow could be due to the crown morphology of the dominant species, Castanopsis sieboldii, that has inclined branches and concave shaped leaves. Mean pH in the precipitation was 6.22, and decreased significantly as the water passed through the canopy. Concentrations of total N, DOC, K, Na, Ca, and Mg showed a clear pattern of enrichment in both throughfall and stemflow compared to rainfall. The proximity to the Pacific Ocean strongly influenced the nutrient fluxes via rainfall at our site as illustrated by the extremely high Na fluxes via rainfall (213 kg Na ha -1 y -1 ) and throughfall plus stemflow (291 kg Na ha -1 y -1 ). The mean annual nutrient inputs (in kg ha -1 ) were: total N 43, P 2.6, K 76, Ca 49, Mg 30, Na 291, Al 1.8, Fe 1.0, and Mn 1.1. The input of DOC reached 361 kg C ha -1 y -1 . The high nutrient inputs via net precipitation (throughfall plus stemflow) especially for N at our site is thought to reflect the frequent occurrence of sea salt-induced stress and serious herbivory by insect.Castanopsis sieboldii / dissolved organic carbon / evergreen broad-leaved forest / nutrient cycling / stemflow / throughfall Résumé -Partition des précipitations et flux de nutriments dans une forêt subtropicale d'Okinawa au Japon. La partition des précipitations entre eau arrivant directement au sol et écoulement le long des troncs et flux hydrochimiques liés a été étudié pendant 3 ans de janvier 1998 à décembre 2000 dans une forêt feuillue à feuilles persistantes de l'île d'Okinawa au Japon. Mensuellement des échantillons d'eau étaient collectés pour déterminer les concentrations et les flux des bioéléments. Les précipitations annuelles moyennes pendant la période étudiée ont atteint 3325 mm. Les typhons jouent un rôle central dans l'hydrologie de la forêt étudiée avec 11 typhons contribuant à 29,1 % des précipitations totales pour les 3 ans de la période d'étude. L'eau arrivant directement au sol et l'écoulement le long des troncs représentent respectivement 53,9 % et 30,9 % des précipitations incidentes annuelles, impliquant une interception des précipitations de 15,2 %. La part importante de l'écoulement le long des troncs pourrait être dû à la morphologie des couronnes de l'espèce dominante Castanopsis sieboldii qui a des branches inclinées et des feuilles de formes concaves.

“…Forest litter acts as an input-output system of nutrients and the rates at which forest litter falls and, subsequently, decays contribute to the regulation of nutrient cycling, as well as to soil fertility and primary productivity in forest ecosystems [2,5,15,20,23,26,27,32]. Thus, it is critical to understand the nutrient dynamics of litter in these forest ecosystems [2,41,45].…”

“…Thus, it is critical to understand the nutrient dynamics of litter in these forest ecosystems [2,41,45]. Despite many studies carried out on litterfall and decomposition dynamics, largely on temperate forests [2,7,16,17,20,32,41], few attempts have been made to comparatively measure litter and nutrient cycling in natural and planted forests under similar climatic and edaphic conditions in subtropical China. The objective of this study, covering a 3 year period, were to: (i) examine the production of forest litter and its patterns in four plantation forests of Cunninghamia lanceolata (Chinese fir, CF), Fokienia hodginsii (FH), Ormosia xylocarpa (OX), and Castanopsis kawakamii (CK), and an adjacent natural forest of Castanopsis kawakamii (NF); (ii) quantify nutrient return through litterfall in the five forests; and (iii) determine the rate of dry-matter loss and of nutrient release from decomposing leaf litter in the five forests.…”

-The amount and pattern of litterfall, its nutrient return, initial chemistry of leaf litter, and dynamics of N, P and K associated with leaf-litter decomposition were studied in 33-year-old plantations of two coniferous trees, Chinese fir (Cunninghamia lanceolata, CF) and Fokienia hodginsii (FH), and two broadleaved trees, Ormosia xylocarpa (OX) and Castanopsis kawakamii (CK), and compared with that of an adjacent natural forest of Castanopsis kawakamii (NF, ~150 year old) in Sanming, Fujian, China. Mean annual total litterfall over 3 years of observations was 5.47 Mg·ha -1 in the CF, 7.29 Mg·ha -1 in the FH, 5.69 Mg·ha -1 in the OX, 9.54 Mg·ha -1 in the CK and 11.01 Mg·ha -1 in the NF respectively; of this litterfall, leaf contribution ranged from 58% to 72%. Litterfall in the OX, CK, and NF showed an unimodal distribution pattern, while for the CF and FH, the litterfall pattern was multi-peak. The highest annual Ca and Mg returns were noticed in the FH and in the CK, respectively. The amounts of N, P, and K which potentially returned to the soil were the highest in the NF. The loss of dry matter in leaf litter exhibited a negative exponential pattern during the 750-day decomposition. Using the model x t = A + Be -kt , the annual dry matter decay constants (k) ranged from 1.157 in CF to 4.619 in OX. Initial lignin concentration and lignin/N ratios showed significantly negative correlations with k (r = -0.916, P = 0.011; r = -0.473, P = 0.041), whereas initial N concentration showed low positive correlations (r = 0.225, P = 0.038). Using the model x t = A + Be -kt , the decay constant of N (k N ) ranged from 0.769 in CF to 4.978 in OX; the decay constant of P (k P ) ranged from 1.967 in the OX to 4.664 in the NF; and the decay constant of K (k K ) seemed very similar among these forests (5.250-5.992). The decay constants of nutrients during leaf-litter decomposition can be arranged in the sequence of k K > k P > k N , except for leaf litter of OX wherelitterfall / nutrient return / litter decomposition / reafforestation / natural forest / Cunninghamia lanceolata / Fokienia hodginsii / Ormosia xylocarpa / Castanopsis kawakamii Résumé -Chute de feuilles, retour de nutriments et décomposition des feuilles de la litière dans quatre plantations en comparaison avec une forêt naturelle en Chine subtropicale. La quantité et la dynamique de chute de litière, le retour des nutriments, la composition chimique initiale des feuilles de la litière et la dynamique de N, Pet K associée à la décomposition de la litière ont été étudiés dans 2 plantations de conifères (Cunninghamia lanceolata, CF and Fokienia hodginsii, FH) âgées de 33 ans et 2 peuplements feuillus (Ormosia xylocarpa, OX et Castanopsis kawakamii, CK), comparativement à une forêt naturelle adjacente de Castanopsis kawakamii, NF, âgée d'environ 150 ans à Sanming, Fujian, Chine. Sur 3 années d'observations, la moyenne annuelle de chute de litière a été de 5,47 Mg·ha -1 pour CF, 7,29 Mg·ha -1 pour FH, 5,69 Mg·h -1 pour OX, 9,54 Mg·hg -1 pour CK et 11,01 Mg·h...

-We compared Quercus petraea monocultures with adjacent mixed oak-hazel (Corylus avellana) stands at gentle (14°) and steep (25°) slopes of the Ahr-Eifel. The influence of hazel on forest floor mass, soil nutrients, microbial properties and on the abundance of Lumbricidae was studied. Litter mass was greater in mixed stands than in oak monocultures, resulting in a thicker Ah-horizon. Additionally, the PO 4 3-, Ca 2+ -and Mg 2+ -contents were higher and the Al 3+ -content lower in the upper soil of mixed stands. In contrast, the contents of organic carbon , total nitrogen and the C/N ratio did not differ between the two soils. Basal respiration, specific microbial activity (qCO 2 ) and carbon mineralisation (C min ) were higher in mixed stands than in oak monocultures. Lumbricidae showed low densities in three of the stands studied (15-21 ind./m 2 ) and were almost absent at the oak monoculture on the steep terrain (2 ind./m 2 ). oak / hazel / decomposition / soil nutrients / LumbricidaeRésumé -Le noisetier améliore la qualité du sol des peuplements de chênes de basse montagne en Allemagne. Nous avons comparé des monocultures de type Quercus petraea avec des cultures adjacentes mixtes composées de chênes et de noisetiers (Corylus avellana) situées sur des pentes (14°/25°) différentes. L'influence du noisetier sur la masse de litière, les substances nutritives du sol, les propriétés microbiennes et l'abondance de Lumbricidae at été étudiée. Cette étude a montré que la masse de litière est plus élevée dans les cultures mixtes que dans les monocultures de chênes ; il en résulte un épaississement de l'horizon Ah. En outre, les teneurs en PO 4 3--P, Ca 2+ -et Mg 2+ -sont plus élevées et les teneurs en Al 3+ -plus faibles dans les couches supérieures des sols de cultures mixtes. Par contre, la teneur en carbone organique, en azote total ainsi que la relation C/N ne diffèrent pas. La respiration de base, l'activité microbienne spécifique (qCO 2 ) et la minéralisation carbonique (C min ) sont plus élevées dans les cultures mixtes que dans les monocultures de chênes. Les Lumbricidae présentent des densités faibles dans trois des cultures étudiées (15-21 ind./m 2 ), tandis qu'ils sont pratiquement absents dans les monocultures de chênes en terrain escarpé (2 ind./m 2 ). chêne / noisetier / décomposition / substances nutritives du sol / Lumbricidae
