Mangrove soil condition was essential factor in mangrove reforestation and coastal rehabilitation projects. The present survey was made to study of the some physico-chemical parameters of soil at five places of Machilipatnam coastal regions during the year 20012-2013 at four-seasonal intervals. This study was carried out using field determination of colour and texture, and a low-cost electrochemical approach was used for pH, salinity measurements The soil properties, colour, texture, pH , salinity,electrical condititivity, organic carbon, macronutrients (N,P)and micronutrients(Zn,Mn,Fe,Cu,P2O5) are determined in mangrove ecosystem. The results showed that soils in the mangrove forest are dark black in colour, and are made up of both clay and silt, soil pH range from(8.35 to 8.79) which are alkaline. Soil salinity range from (20 to 32 ppt) decreased with increasing distance from the tidal coast electric conductivity range from (10.26 to 16.22 m.mohs/cm).Available nitrogen(29.4 to 81.2ppm),phosphorous range from(3.32 to 5.89 ppm) were maximum in monsoon and minimum in summer . The micronutrients such as zinc(0.31 to 0.64ppm), copper(0.9 to8.8 ppm) , iron (9.50 to 19.7)and manganese(17.9 to60.2 ppm) have variation in comparison to different areas
