Nutrient dynamics in decomposing needles ofPinus luchuensisafter typhoon disturbance in a subtropical environment

Abstract: -Decomposition of typhoon-generated and normally fallen needles and their dynamical patterns of nutrient release for ten elements (C, N, P, K, Ca, Mg, S, Fe, Al, and Mn) were investigated over 3 yr using the litterbag technique in a subtropical pine plantation (Pinus luchuensis Mayr.) in Okinawa, southwestern Japan. After 3 yr, decomposition rates (k values) were 0.361 and 0.323 yr −1 , respectively, for typhoon-generated and normally fallen needles. The typhoon-generated needles decomposed significantly more … Show more

“…Our results were consistent with many other studies reporting that litter with high initial N concentration exhibits relatively faster decomposition rate (Berg and Matzner, 1997;Fog, 1988;Sundarapandian and Swamy, 1999;Xu, 2006). In Control plots with no additional experimental N input, rates of litter mass loss and litter C loss tended to be faster in nutrientrich needles than in nutrient-poor needles.…”
