Soil Carbon Contents of Teak Plantation in Agroforestry Farming of Ban Tham Suea, Kaeng Krachan District, Phetchaburi Province, Thailand

Increase of atmospheric carbon dioxide is a serious global environmental concern. Teak plantation can store substantial amount of carbon. Soil carbon contents and properties were studied in 3, 6 and 13-years-old teak plantations located in agroforestry farming areas of Ban Tham Suea, Kaeng Krachan District, Phetchaburi Province. Soil samples were collected at  0-30 cm depth by a non-disturbed method from 14 locations. Physical and chemical soil properties including texture, soil bulk density, total nitrogen, available phosphorus, available potassium and soil organic carbon were analyzed. Finding revealed that soil texture as sandy loam, silt and clay loam with bulk density was 1.2, 1.2 and 1.3 g/cm3 and total nitrogen 0.06, 0.09 and 0.10 % in 3, 6 and 13-year-old teak plantation, respectively. Soil organic matter was the highest at 2.84 in 3-year-old teak plantation, followed by 2.09 and 1.96 % in 3, 6 and 13-year-old teak plantation, respectively. Highest available phosphorus was recorded at 3-year-old teak plantation at 153.08, followed by 6 and 13-year-old teak plantation at 87.88 and 40.90 mg/kg, respectively. Available potassium was highest at 118.01 in 3-year-old teak plantation, followed by 6 and 13-year-old teak plantation at 85.58 and 60.14 mg/kg, respectively while soil carbon stock was highest in 13-year-old teak plantations, followed by the 6 and 3-year-old teak plantations at 37.44, 29.52 and 19.08 tC/ha, respectively.
