The aim of this study was evaluate if the anaerobically digested cattle slurry (ADCS) and liming could increase the availability of the applied fertilizer P to the forage corn plant in acid andosol. We conducted two pots experiment to verify the aim described above. In the first experiment, the availability of fertilizer P to forage corn did not showed significant difference between the following two application methods of the P with the ADCS; 1) the ADCS was mixed with the P and then applied to the soil, and 2) the ADCS was mixed with the soil at first and after that, fertilizer P was applied. The ADCS could apparently increase the availability of the P to the plants, when the same rate of NH4-N was applied but total applied N including organic N in the ADCS was considerably different between the ADCS and chemical fertilizer treatment. The treatments without lime had a greater growth of the plants comparing with the treatments with lime. Our results suggested the possibility that the released Mg from the commercial lime (CL) might affect the plant growth and P uptake.
