Maize yield after long-term application of pig slurry.

Organic wastes produced in large quantities in pig farms, such as liquid swine manure (LSM), can become a good alternative source of nutrients for agriculture, thus enabling total or partial replacement of mineral fertilizers in agricultural crops. The aim of this study was to evaluate the use of LSM as a substitute of mineral fertilizer in the maize crop under Cerrado soil conditions. The treatments consisted of using mineral fertilization recommended for the maize crop; without fertilization; and LSM doses (25, 50,100 and 200 m3 ha-1). Maize grain yield was evaluated in the 2004/2005, 2005/2006, 2006/2007, 2007/2008, 2009/2010, 2011/2012 and 2013/2014 crop seasons. The mineral fertilization in maize can be replaced by pig slurry doses from 100 m3 ha-1 in a Cerrado soil (dystroferric Red Latosol with clayey texture) with no loss of yield components.
