Rice crops require sufficient amount of water for their development, but water is often a limiting factor if it is grown on dry Vertisol soils. The study aimed to determine the monthly water availability and water available of soil profiles for paddy on Endoaquert Ustic of Paguyaman. The research was conducted on 2 pedon of Vertisol soil profiles, which were pedon from Sidomukti Village of Mootilango District of Gorontalo Regency and from Sosial Village of Paguyaman District of Boalemo Regency. The soil profile was constructed and sampled according to soil survey principles. Climate data were collected from the Sidodadi and Molombulahe climate stations, including: rainfall data (mm), temperature (°C), relative humidity (%) and wind speed (km hour-1). Soil data used, including: soil water content of field capacity (pF = 2.5) and permanent wilting point (pF = 4.2) and root depth on 30 cm (rice roots). Monthly water availability analysis was using water balance method followed by water balance of soil profiles. The results showed that monthly water availability of Vertisol from Sidomukti Village was higher than Vertisol from Social Village. Water available of Vertisol soil profile from Sidomukti Village more by 41.09% compared to Vertisol from Social Village.
