Outdoor research was conducted in the coastal region of Parangtritis from December 2015 up to April 2016, with the purpose is to determine the soil characteristic of coastal land of Parangtritis and its suitability for soybean cultivation. This research was conducted using the observation method by collecting primary and secondary data. Primary data were soil characteristics which determined using the laboratory analysis procedures, while secondary data were supporting information obtained from local government agencies. The results showed that the coastal land of Parangtritis had a sandy texture, very fast soil drainage, the effective depth of low to moderate soils, low salinity, low cation exchange capacity, percentage saturation of medium to high bases. Based on the results of the analysis of primary and secondary data, actually the sandy land of Parangtritis is categorized into land suitability class S3r-1; r-2 for soybean plants, with soil drainage and texture as a limiting factor. Potentially, to reduce the negative effects of existing limiting factors, the addition of large amounts of organic matter, inorganic amendments, and NPK fertilizer is highly recommended.
