The study of agriculture lime applications and super phosphate fertilizer on available P in Inceptisol Rangkasbitung, West Java with corn as indicator, was conducted in the 'green house" of the Faculty of Agriculture IPB Bogor. The specific of this study is to know the available of P in inceptisol with agriculture lime and some of P source treatment. Experiment was designed in completely randomized design with three replications was used. As treatment were six of P fertilizer dosage; super phosphate-36 is 11.29 g/pot equal to 36.13 ton/ha; agriculture lime (KAPTAN) 52.59 g/pot equal to 168.29 ton/ha: agriculture of liming + super phosphate-36 (52.59 g/pot equal to 168.29 ton/ha + 11.29 g/pot equal to 36.13 ton/ha); super phosphate of agriculture lime (KSP) 54.56 g/pot equal to 174.59 ton/ha; rock phosphate 24.29 g/pot equal to 77.73 ton/ha. The result indicated that the application of P from agriculture lime and super phosphate can increase condition in Inceptisol and increase the cation exchange capacity and the rock phosphate is the best for increasing the available of P (55.70 me/100 g) for corn in Inceptisol Rangkasbitung, West Java with 77.73 ton/ha rock phosphate adding
