dc.description.abstract | Mangroves produce litter that will undergo a decomposition process which is then
used as a source of nutrients for plants and is also a source of food for fish and
important invertebrates. The purpose of this study was to measure the
decomposition of Rhizophora apiculata leaf litter and to know the nutrient content
carbon (C), nitrogen (N) and phosphorus (P) in leaf litter R. apiculata released
during the decomposition process. The study was conducted from February to
May 2017 in Bagan Asahan Village, Tanjungbalai Sub-District, Asahan Regency,
North Sumatra Province. The determination of research station using purposive
sampling method at three stations with station determination based on observation
of availability of R. apiculata mangrove species. The results showed that leaf
decomposition rate of R. apiculata leaf on the 90th day at station I was worth
13,04 station II was 11,42 and station III was 10,24. The content of carbon
nutrients during the 90-day decomposition process is station I of 16.24%, station
II of 15.29% and station III of 15.42%. Nitrogen nutrient elements decomposed
on the 90th day were station I of 2.69%, station II of 2.57% and station III of
2.75%. Phosphorus nutrient content during 90 days decomposition process is
station I 0,02%, station II 0,02% and station III 0,01% | en_US |
