Soil resources of the Phang Nga weather information from the map group sets the scale of 1:50,000 soil of land development department in Phang Nga province, which consists of a group of soil characteristics, soil series, 22 group will vary according to the soil and landform, which origin is as follows: -Sandy Beach and dunes (Beach ridges and sand dune) is a narrow, parallel to the West Coast. Caused by wave action or currents, sea borne sand to remove the mess by North sand. The dunes rise characteristics of sandy soils with wave corrugation ramp area weather. The slope is about 2-4% of the fertility of the soil is low. Utilization of land, mainly coconut plantation. -An area where the sea Plains Group (Active tidal flat) area is a rich coastal waters up to on a regular basis. Most of the estuary area of the district khura buri. Kamala takua PA Thap put district and city Caused by the sediment of the river mouth area, mainly sediment texture, so the soil found in this area, therefore, it is often contaminated sand or soil or grey clay lane and soil salinity, soil salinity, acid, alias, because the influence of sea water utilization of land is mostly mangroves. -River sediment Plains (Alluvial plain). A soil area along the waterfront (Levee) caused by river silt deposit in the convection came riverbank has a slope of about 2-4% of the soil is clay soils are well-drained, utilization of land, mostly planted fruit trees. Taphak yard of plain river level low (Low terrace) is a smooth manner. Caused by the sediment which is borne on a long time to come. Therefore, it makes the soil texture soil characteristics are different, such as clay. Loose soil contaminated clay. Sandy clay, or clay loose Sandy glutinous, etc. generally have bad drainage district area is found, mueang takua thung district. Utilization of land use and planting rice and palm oil. A wave of taphak River (Old alluvial terrace) is Don next plateau taphak low levels of water in a courtyard, which is caused by the change of direction, the river and the erosion of the River in the past. Making terrain such as hills There is similar to wave the soil most resembles a coarse texture soils, or rather a sand. Some gravel is found in water. Utilization of land, planting rubber trees and oil palm, coconut, The area is the area child left from corrosion (Erosional surface), this area used to be a hill or a mountain before. Subsequently, natural corrosion occurs when skin surfaces become steep sloping to undulating lawn lawn as seen in the current. The characteristics of the soil in this area varies by the type of ground stone. Utilization of land, planting rubber and palm oil. บริเวณที่ลาดเชิงเขาและเนินเขา (Foothill slope and hilly) ลักษณะพื้นที่เป็นเนินเขาเตี้ยๆ มีความลาดชัน 16-35 % ที่ดินเกิดส่วนใหญ่เกิดจากการสลายตัวของหินพื้นล่างหรือเกิดจากหินลาด เชิงเขา ส่วนใหญ่จะเป็นดินตื้นมีเศษหินปะปน การใช้ประโยชน์ที่ดินเป็นป่าไม้ธรรมชาติ และปลูกยางพารา บริเวณที่เป็นภูเขาและเทือกเขา (Hills and mountains) เป็นภูเขาและเทือกเขาต่างๆ สลับซับซ้อน มีความลาดชันมากกว่า 35% เป็นทิวยาวตามแนวเหนือใต้และทางด้านทิศตะวันออก ได้แก่ ทิวเขาภูเก็ต ประกอบด้วยหินชนิดต่างๆ เป็นแหล่งต้นน้ำลำธาร พืชพรรณที่ขึ้นอยู่เป็นป่าดิบชื้น
