The five essential nutrients which is Phosphorus(P), magnesium(Mg), calcium(Ca),
potassium(K) and manganese(Mn) were assessed in Melaleuca Cajaputi, Rhizophora
Apiculate , Ceriop Zippeliana, and Bruguiera Cylindrica. The decomposition rates of
each species influenced by the concentration of nutrient states above. The result
shows that the Melaleuca Cajaputi has the lowest concentration of K (1134.69 mg/kg)
, Ca ( 3215.35 mg/kg) Mg (1434.17 mg/kg) P (1202.24 mg/kg). While the highest
concentration of P (1819.85 mg/kg) and Ca(9870.773 mg/kg) found in the Bruguira
Cylindrica , Mg (6816.746023 mg/kg) in Ceriops Zippeliana , K(10323.50 mg/kg)
Rhizophora Apiculata. The concentration of the nutrients was increase from day 0 until
30 and decrease start from day 60 to day 180.
