Because of their size and the large daily produced quantity of fresh manure many feedlots for finishing beef cattle struggle with sound manure management often leading to environmental pollution and a waste of valuable resources. The Argentinian brothers del Barrio, owning the El Trébol farm enterprise with about 30,000 heads of beef cattle, of which 12,500 are kept on feedlots, successfully utilize these valuable resources; not because it generates additional income but because it reduces pollution of their environment.
Every day they scrape off the top layer of the 50 feedlots and pile-up this mixture of manure and topsoil to be composted. The final product is compost containing 65% organic matter and many valuable crop nutrients. The compost is sold as organic fertilizer to horticulturists and retailers in the area of Buenos Aires. The del Barrio brothers herewith demonstrate that even in high density cattle situations like the feedlots manure management is possible and profitable.
El Trébol is partner of the National Feedlot Chamber, of which Guillermo del Barrio is at present the vice president. In this position he is promoting the development of a manual of good environment practices.
