Lab Analysis
Rosa Bitamina (RB) had been analyzed by ESPEK Research and Advisory Services (ERAS), Bangi, Selangor to
determine sample’s content. Result of analysis as showed in Table 2. From the result, C/N ratio for RB is 5.21 which
indicate that the sample is predominantly marine origin (Meyers, 1994). Thus, this data confirmed the marine-based
properties for RB. Result also showed that RB contains nitrogen, phosphorus and potassium which are the macro
elements needed for plant growth. High number of iron (Fe) which is 292.37 ppm had increased the plant resistance
