Quantity and quality of litterfall in young oak stands

Litterfall, an important component of the nutrient cycle in forest ecosystems, was measured for 9 years in young oak stands on two localities classified as beech-oak climax (Fageto-Quercetum). We estimated that about 4 Mg of dry mass per hectare fell each year. Nutrient content in the litterfall represents annually per hectare approximately 40-55 kg of nitrogen, 2-3 kg of phosphorus, 7-16 kg of potassium, 41-73 kg of calcium and 6-7 kg of magnesium. The amount of litterfall is positively correlated with stand basal area and with the death of suppressed tress with small crowns. We found a positive correlation between annual litterfall and the sum of precipitation and a negative correlation between annual litterfall and temperature in summer.

“…drier and warmer areas). Martin et al (1996) found that the inter-annual variability of litterfall amount in Q. rotundifolia stand was caused by water stress in summer. Dry spring weather was the reason for the lower amount of litterfall also in Q. pyrenaica stand in Spain (Diaz-Pines et al 2011).…”

“…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].…”

Litterfall, nutrient return, and leaf-litter decomposition in four plantations compared with a natural forest in subtropical China

-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.
