Drought is a phenomenon resulting irrelevancy or climate in General as a lack of rainfall in the area. Droughts also impact on the surface layer of the soil where the moisture content required to balance organic matter, soil biota, as well as the survival of vegetation. Its categorized by NOAA as drought farms/land. This research is finding potentially soil drought spatially and measured trough index algorithm with wetness and brightness index made by Jensen in Chen (2014) in the District of Kebumen, to see the condition of the organic matter and soil moisture as well as indicators of soil drought by 2015, as well as linked with meteorological drought by the method of standardized precipitation index (SPI) (30 years of rainfall data) statistically. Both the index (wetness and brightness) are calculated on the data of satellite imagery. The results say rain-fed rice land, pasture and moorland is tend to drier that average on months (February, June and December 2015). Those land use become vulnerable to agricultural drought when dry season occur.
