【 摘 要 】

Pond soil quality is an important factor within aquaculture. A different characteristic may have different effects to the water quality. Fish farming has been tried to use earthen pond in zone II of the reclaimed tidal lowland areas with a different degree of success. The objective of this study was to investigate the soil and water quality correlation as an initial point in interpreting the pond quality in tidal lowlands. Dried bottom soil and water samples were collected from 30 ponds in dry season at temperature ±29°C and measured in situ and ex-situ. The results indicated that both soil and water were in poor condition. Soil pH averaged 3.50-5.86, while water pH averaged 3.9-6.8. There was a weak correlation between pH soil and water as 0.364. There was no correlation between soil pH with the low of total alkalinity and hardness. The soil had a lack of cations (Mg2+ and Ca2+), a high percentage of organic carbon (3.91±0.19%) and iron (84.49±8.54 mg/Kg). Location of a pond in tidal lowland which contains of pyrite generated the high of iron oxide and caused acidity in either soil and water. Soil amelioration and management must be considered appropriately in order to increase the pond productivity.
