- Mineralization of organic fertilizers in saline soil is determined by the level of soil salinity. The higher levels of soil salinity, the lower the ability of organic matter mineralization. Evaluation mineralization levels assessed by the content of N, P, K, C-org in organic fertilizer. Research objectives were to assess the ability of the various formulas of mineralization of organic fertilizer to provide nutrients and suppress soil salinity. Nutritional NPK fertilizers are classified by grade. The results showed that the formula with high-grade organic fertilizer was obtained from a mixture of manure, compost, guano, and straw. High-grade organic fertilizer is not always effective as the controlling soil salinity and aggregate stability, but can increase the CEC and the availability of N, N Ammonium inhibits volatilization, decrese soil EC, but soil pH was increased. Mineralization rate of organic fertilizer on clay-textured soil (Rungkut and Sedati) more slowly than sandy soil (Buduran). Keywords: grade, mineralization, NPK, organic fertilizers, soil salinity
