Determination of mass balances and ionic balances in animal manure
Liquid and solid fractions of three different pig slurry samples and a poultry manure sample were isolated through high speed centrifugation followed by ultrafiltration. The gross ionic composition of the liquid manure fractions could be described by: K+, Na+, Ca2+, Mg2+, Cl-, bicarbonate, weakly acidic cations (ammonium) and weakly alkaline anions (acetate). Ionic balances showed an agreement of more than 98% between anionic ad cationic species. The elemental composition of a pig slurry solid fraction was determined. Mass calculations based on this analysis accounted for 98% of the total weight. (Abstract retrieved from CAB Abstracts by CABI’s permission)
