The Effect of Broiler Litter, Swine Effluent, and Municipal Biosolids Land Application on Small Plot Pathogen, Antibiotic Resistance, and Nutrient Levels

Purpose

Land applying agricultural and municipal wastes carries an inherent risk associated with nutrient and pathogen runoff and contamination, but with that risk comes a potentially sustainable process to reclaim otherwise residual waste material. Few studies compare the two residuals. The purpose of this study was to investigate the land application of municipal waste water treatment solids (biosolids) versus manure (broiler and swine) and their effect on pathogens, antibiotic resistance and nutrients.…

Antibiotic Losses during Thermophilic Composting

Purpose

Residual antibiotics in land-applied manure and biosolids present a potential threat to public and ecological health, so it is important to determine antibiotic removal efficiencies for manure and biosolids waste management practices and to identify conditions that enhance antibiotic degradation.…
