“…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].…”

-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.

“…With respect to thinning, Caldentey et al (2001) reported that annual litterfall flux decreased by 50% two years after thinning in an under-cover silvicultural system in which 55% of the initial basal area was removed. However, in agroforestry systems (AFS), side pruning is typically performed early in the planting since pruned trees usually produce less litter (Jamaludheenn and Kumar, 1999).…”

RESUMENSe evaluó la producción y la calidad de hojarasca en un banco de forraje puro y mixto de Leucaena leucocephala (Lam.) de Wit, Guazuma ulmifolia Lam. y Moringa oleifera Lam. en monocultivo y asociadas en la época de lluvias y sequía, en un diseño de bloques completos al azar con cinco tratamientos y cuatro repeticiones, en densidades de 10,000 y 20,000 plantas·ha -1 . En cada unidad experimental se instaló una malla colectora de hojarasca de 1.6 m 2 y la hojarasca se recolectó durante un año. Se registró el peso seco por tratamiento y época para determinar la fracción de N, C y P y la relación C:N. La producción mayor de hojarasca fue en lluvias, L. leucocephala en monocultivo y asociada con G. ulmifolia obtuvo mayor producción con 1,022 y 1,542 kg MS·ha -1 ·año -1 , respectivamente. L. leucocephala presentó las mayores contribuciones totales de N, C, y P con 22.0, 443.0 y 0.96 kg MS·ha -1 ·año -1 . L. leucocephala con M. oleifera aportó mayores cantidades de N y C (23.2 y 363.8 kg MS·ha -1 ·año -1 ). El mayor aporte de fósforo fue para L. leucocephala con G. ulmifolia (0.74 kg MS·ha -1 ·año -1 ), se concluye que la asociación de especies promueve una mayor producción de hojarasca y aporte de nutrimentos en comparación con los monocultivos. ABSTRACTLitterfall production and quality in pure and mixed fodder banks of Leucaena leucocephala (Lam.) de Wit, Guazuma ulmifolia Lam. and Moringa oleifera Lam. were evaluated during the rainy and dry season, using a completely randomized block design with five treatments and four replications in densities of 10,000 and 20,000 plants·ha -1 . In each experimental unit, a 1.6 m 2 litter mesh collector was installed, and the litterfall was collected throughout one year. Dry weight was recorded by treatment and seasons to determine the fraction of N, C and P and the C:N ratio. The highest litterfall production was in the rainy season. L. leucocephala in monoculture and intercropped with G. ulmifolia showed the highest production with 1,022 and 1,542 kg DM·ha -1 ·1yr -1 , respectively, and L. leucocephala had the highest total contributions of N, C, and P with 22.0, 443.0 and 0.96 kg DM·ha -1• yr -1 . L. leucocephala with M. oleifera provided greater amounts of N and C (23.2 and 363.8 kg DM·ha -1 ·yr -1 . The greatest input of phosphorous was by L. leucocephala and G. ulmifolia (0.74 kg DM·ha -1 ·yr -1 ). It was concluded that the association of species promotes greater litter production and nutrient intake compared with monocultures.
