The main objective of the present study was to quantitatively characterize the swine slurries in terms of physical, biochemical, and microbial parameters, in order to find an easy means for predicting nutrient matter by easily determinable parameter of EC content in swine slurries. The regression equations were presented and compared for nutrients and other parameters with EC. The data obtained could be useful for facilitating the implementation of Good Management Practices in South Korean swine farms as well as other countries. It was found that the precise characterization of animal waste is an essential guide for the development of new environmental technologies. Swine
slurries observed significant variations in the physico-biochemical properties, macro and micronutrients. Despite EC proved to be a good indicator for predicting nutrients (TN, NH3-N, TK, Na) and other parameters (SG, TS, VS, FS, TDS, TCOD, SCOD) in the slurry. Hence, single EC meter is satisfactory for in situ determination of slurry characters. The data and correlations could be used for systematic management of swine manure and estimate the nutrient contribution to the agricultural fields in South Korea as well as other countries.
