This survey research was set for soil analysis in orange garden at Nongbuo district Amphur Banpaew Samutsakorn province. Soil quality comparing in three areas of orange garden such as orange mixed other plants area, Khaewwan orange area and Shaeng orange area were analysed at the level 6 and 12 inches of soil depth. Soil fertility evaluated indices were soil pH, organic matter, available phosphorus and available potassium. The result showed that the soil pH in orange mixed other plant area, Khaewwan orange area and Shaeng orange area at the level 6 inches were 6.4, 7.1 and 6.7 and the level 12 inches were 5.9, 5.7 and 7.1. Organic matter content in orange mixed other plants area, Khaewwan orange area and Shaeng orange area were analysed at the level 6 inches were 2.32, 3.02 and 3.36 g/Kg and the level 12 inches were 2.22, 2.22 and 3.22 g/Kg. Available phosphorus content in orange mixed other plant area, Khaewwan orange area and Shaeng orange area at the level 6 inches were 5.12, 4.84 and 7.53 mg/Kg and the level 12 inches were 4.20, 4.17 and 6.39 mg/Kg. Available potassium content in orange mixed other plants area, Khaewwan orange area and Shaeng orange area were analysed at the level 6 inches were 59.9, 57.2 and 47.4 mg/Kg and at the level 12 inches were 50.6, 41.7 and 52.8 mg/Kg. The conclusion of soil quality analysis as soil fertility evaluated indices had no statistical difference at level 0.01. But the available phosphorus and the available potassium were low level and near low level as comparing with soil fertility standard in Thailand. Soil fertility analytical data were used to increase fertilizer in order to improve soil quality in orange garden areas.
