contents Characteristics and problems of marginal soils from acid sedimentary rocks in KalimantanMarginal or suboptimal soils are potential for agricultural development such as food crops, estate crops, and industrial planted forest. These soils have low fertility status and susceptible to erosion. In Kalimantan, the marginal soils cover about 30.15 million ha or 57.22% of the total island area, with the major soils consist of Ultisols, few Oxisols, and Inceptisols. The physical properties of marginal soils from acid sedimentary rock are mostly influenced by the type of parent materials ( sandstone or claystone ) , while the chemical properties showed the similar characteristics indicating acid soil reaction, vary in organic matter, and low in cation exchange capacity, exchangeable bases, base saturation, mineral reserve, as well as P and K potentials, but the Al saturation is high.
