Abstract

 The physicochemical properties of soils from sago-palm-growing areas were studied and compared with the properties of the soils of surrounding cashew and cacao fields and the paddy fields around Kendari, Southeast Sulawesi Province, Indonesia. Soil samples were collected from 0-15 cm and 15-30 cm depth from Lalomasara and Lakomea in the Pohara Subdistrict, Watulondo in the Puwatu Subdistrict, and Konda in the Konda Subdistrict. The soil types in the sampled areas were mineral soil except for those in Watulondo, which were peat soil. The results revealed that the physicochemical properties of the mineral soils in the sago fields varied depending on the sites and kinds of crops being cultivated. The bulk densities ranged from 0.3-1.1 g cm^-3, and the texture varied from sandy loam to silty clay. The soil pH dominantly ranged from very acid to neutral. The nutrient contents of sago-palm-growing soils ranged from low to very high for total-N, very low to medium for available-P, low to medium for exchangeable-K, low to high for CEC, and low to very high for total-C content. The nutrient contents and pH of soils surrounding cashew and cacao were either lower or equal, but they were higher in bulk densities. However, higher total-C, N, and CEC and lower bulk density were observed in the neighboring paddy field than in sago palm fields due to the application of fertilizer and the straw incorporated into the soil every year. The pH in the peat soil in the sago-palm-growing areas ranged from very acid to acid, very high in CEC, organic-C, and total N contents, and low in available-P and exchangeable-K, with a bulk density of 0.3 g cm^-3. The effects of the soil physicochemical properties on the growth and starch production were discussed.
