GARCIA, Ana R. et al. Observaciones, desafíos y oportunidades en el manejo de efluentes de feedlot en la provincia de Buenos Aires, Argentina. Ecol. austral [online]. 2015, vol.25, n.3, pp.255-262. ISSN 1667-782X.

Observations, challenges and opportunities in feedlot effluents management in Buenos Aires Province, Argentina: The accumulation of beef cattle manure on feedlot pen surfaces generates large effluent volumes which can impact surface and groundwater quality. The aim of this study is to examine and summarize the available information on feedlot effluents management in Buenos Aires Province, highlighting the environmental effects and the weaknesses and future actions suitable to be implemented. We describe the environmental effects of this activity over waterbodies quality and analyze the existing regulations, with special emphasis on criteria and/or discharge levels proposed by legislation. This study reveals some gaps and incongruence as well as needs and opportunities for adjustment and expanding of existing regulations. Finally, an operating scheme used to frame the analysis of different aspects involved in feedlot effluent management is proposed. Such scheme identifies four components defined considering the development of a Nutrient Management Plan (NMP) and the determination of an Effluent Control Criterion (ECC).
