Present study was conducted out during 2015-2016 in Rewa district of Fiji to evaluate available micronutrient (Fe, Cu, Mn and Zn) status and their relationship with the soil properties. Fifty seven sites were selected for soil sampling. The available micronutrient (DTPA extractable) viz., Fe, Mn, Cu and Zn were analyzed using atomic absorption spectrophotometer. The analyzed data revealed that available micronutrients iron (Fe), manganese (Mn) and copper (Cu) were found to be sufficient in most of the soil samples, whereas, available zinc (Zn) was found to be deficient in most of the analyzed samples. Further, availability of Mn, Cu and Zn was found positively correlated with pH of the soils whereas Fe correlated negatively with pH of the soil samples. Available Mn and Cu were found positively correlated with EC of the soils whereas Fe and Zn correlated negatively with EC of the soil samples. Available Fe, Mn, Cu and Zn were found positively correlated with OC of the soils. Findings indicated that soil pH and organic carbon are the main soil characteristics which control the availability of these micronutrients.
