Podsolik soils have various problems including acidity of the soil (pH) and low soil nutrient content. This study aims to determine the effect of guano and bat fertilizers on the availability of P nutrients in podsolik soils, and to determine the best treatment. This study was a pot experiment using a completely randomized design (CRD) with one factor, namely (P1 = Dolomite 2 t ha^-1); (P2 = Guano Fertilizer 0,5 t ha^-1); (P3 Guano Fertilizer 0,5 t ha^-1 and Dolomite 2 t ha^-1); (P4 = Guano Fertilizer 1 t ha^-1 and Dolomite 2 t ha^-1); (P5 Guano Fertilizer 1,5 t ha^-1 and Dolomite 2 t ha^-1). Each treatment was repeated 4 times, so there were 24 experimental units. The results showed that the application of dolomite and guano fertilizers had an effect on the availability of available-P, pH, Ca-dd, and Al-dd. However, it has no effect on Mg-dd in Podsolik soil. The application of dolomite and guano fertilizer with a dosage of 0,5 t ha^-1 guano fertilizer and 2 t ha^-1 dolomite was the best result for the availability of P, Ca-dd and pH.
