Slurry samples, collected from 23 commercial swine farms in South Korea during January to May 2008, were
characterized in terms of various physiochemical parameters: pH, specific gravity, electrical conductivity, total solids, volatile solids, fixed solids, total suspended solids, total dissolved solids, biochemical oxygen demand, chemical oxygen demand, macronutrients (N, P, K, Ca, Na, and Mg), micronutrients (Zn, Fe, Al, Mn, Cu, and Co), heavy metals (Ni, Cr, As, Cd, and Pb), and microbes (total heterotrophic bacteria, coliforms, Escherichia coli, and Salmonella).
