Abstract
|
|
|
|
The purpose of this study is to investigation of the decomposition characteristics in a pilot-scale burial site of livestock in three kinds of typical soils in Korea: sandy loam soil, clay loam soil, and sandy soil. In this study, we confirmed that most of the animals in the condition were decomposed within three years as mentioned in the “Livestock burial regional environmental research guidelines.” We also determined that the decomposition rate of dead cows was higher than that of dead pigs, and that the biodegradation rate depends on the soil types in the following order: sandy soil > clay loam soil > sandy loam soil. The various external environment factors, such as temperature, moisture, pH, earthiness, nutrient, and the burial depth, should be managed properly for appropriate decomposition of dead animals.
