Manure composition emissions can be effected by soil water with the application of poultry manure. The vectors to represent the relationship between soil water characteristics and antibiotic were generated. A Semi-empirical Richards equation is employed to model the law of soil moisture while precise solutions of Richards equation obtained by using the (G′/G) - expansion method and the homogeneous balance method. Then mode l which involves several variables including soil moisture content, soil depth and timescales was assumed according to the exact solutions of Semi-empirical Richards equation. At least one antibiotic was detected in all the soil water and poultry manure samples. And it is worth noting that all of parameters or constants in this function expression were determined by these data.
