Abstract

The intensive use of animal manure is a significant environmental risk to soil water. Manure composition emissions can be effected by soil water with the application of animal manure. The vectors to represent the relationship between soil water characteristics and antibiotic were generated. A Semi-empirical Richards equation is employed to the dynamic models of soil moisture while precise solutions of Richards equation obtained by using the /GG- expansion method and the homogeneous balance method. Then the dynamic models which involve several variables including soil moisture content, soil depth and timescales were assumed according to the exact solutions of Semi-empirical Richards equation. At least one antibiotic was detected in all the soil water and animal manure samples. Results confirmed that the contamination of vegetables by fecal bacteria is mainly due to the use of animal manure.

Keywords: Antibiotic; animal manure; Richards equation; soil moisture; the G /G
- expansion method.
