A liquid waste from methane fermentation was applied on a pasture of grass-legume mixtures to determine its effect and optimum application rate on plant growth. Fresh yields of the pasture increased as the liquid waste application rate increased, especially markedly increased when the 42 ton/10a of waste was applied only. The NPK components in soil and plant was also higher in the plots of liquid application than that of control. Therefore, the optimum application rate of liquid waste was found to be 42 ton/10a. This result indicates that the liquid waste is potentially useful source for a fertilizer and irrigation water.
