Study Productivity And Decomposition Litterfall In Sibolangit Forest, Deli Serdang To Support Field Trip Plantation Ecology
Abstract: The research
was conducted in
mountain rain forest
of Sibolangit, Deli
Serdang, Northen Sumatera.
The objectives of this research are to know litter fall productivity,
decomposition and litterfall nutrients. Litterfall is the fallen leaves, twigs,
flowers and fruits to forest-floor,
which one of the input of nutrients to anorganic sril. This
input is one of the nutrients
cycling to forest ecosystem and the other
form atmosfer and
a lot of animals. Based on
available data on 20 traps, litterfall productivity 5,91 gr/m2/week or 3073,2 kg/ha/year in high
topography. Litterfall productivity 4,92gr/m2/week or 2558,4 kg/ha/year in low
topography. Litterfall decomposition
(lossed of weight) about 25,48% in 30 days ( 1 month ) for meranti ( Shorea sp
) and leaves ofFicus sp had lossed of weight about 8,09% in 30 days ( 1 month
). Ration C/N (Carbon -Nitrogen) litterfall and soil moisture made differrent
litterfall decomposition (lossed of weight)
