摘要：Merauke Regency has 216.196 Ha of mangroves area which most of it was fed by the Maro River. The purpose of this research was to study the chemical, nutrient movement, and physiochemical properties by collecting the soil around the Maro River. 10 collected soil samples (0-20 cm depth) were analyzed using standard methods. The result showed that the average CEC of soils around River Maro is 15.95 cmol/kg. Organic matter and soil moisture content could be the contributor to enhance the CEC of soil. The average organic carbon was 1.34%, while the BOD and COD were 2.44 and 5.70 mg/L. Soil could have different mineralogical content which nutrient around Maro is decreasing due to waste disposal to the river, agricultural practice, and other human activities. Environmental management needs to reevaluate and studies about soil mineralogy strongly recommended.
