Abstract
This research was conducted using observation method by collecting the 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 sandy beaches of Parangtritis beach had a sandy texture, very fast soil drainage, 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 beach 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, in-organic amendments, and NPK fertilizer is highly recommended.
