“…The foliar contents of N, P, K, Ca, Mg, S, Fe, Mn, Cu and Zn in soybeans were not affected (p > 0.05) by treatments (Table 3). Similar results were obtained by Santos et al (2012), Sediyama et al (2014), Seidel et al (2010) and Bócoli et al (2016), which detected no changes in foliar concentrations of N, P and K in squash, peppers and corn, respectively, with the application of pig manure. However, Corrêa et al (2008) noted that, with increasing doses of organic waste, N content increased in soybean leaves.…”

The application of liquid swine manure (LSM) in the soil as biofertilizer is one of the most recycling alternatives adopted, because the nutrients contained in this residue can override, in part or totally, commercial fertilizers, crop productivity with a reduction in production costs. The goal with this work was to evaluate the use of LSM as a substitute of mineral fertilization on soybean culture in conditions of Savannah in 2014/2015. The experimental design was of randomized blocks with three replications. The treatments consisted of the use of mineral fertilizer recommended for soybean culture; without fertilization; and doses of LSM (25; 50; 75 and 100 m³ ha -1 ). The levels of N, P, K, Ca, Mg, Cu, Zn, Mn and Fe in leaves, seeds and dry matter from the shoot, plant height and productivity of grain was assessed. There was no statistical difference between treatments that received mineral fertilization (P and K) and the treatments that received pig manure, indicating that the use of pig waste as bio fertilizer on soybean fertilization may be a promising alternative. The mineral fertilizer in soybean culture can be replaced by shots of LSM from 80 m³ ha -1 with no losses in grain productivity in a clayey dystroferric Red Latosol. The applications of doses of pig manure generally did not promote increase in the content of nutrients in grains and in the extraction of nutrients by the aerial part of the soybeans plants.

“…Compared with the NPK fertilization recommended for maize (Souza & Lobato, 2004): the LSW dose of 200 m 3 ha -1 exceeded in relation to N; none of the doses met the requirements of P; and LSW doses above 100 m 3 ha -1 were superior in relation to K. Swine wastes can be considered as unbalanced fertilizers, since they have nutrients in disproportionate amounts in relation to the requirements of the plants (Berwanger, 2006), as opposed to mineral fertilizers, which can be specifically formulated, according to the conditions of cultivation and soil. Hence, excessive or successive fertilizations with swine waste can cause alterations in soil chemical attributes (Scherer et al, 2010;Lourenzi et al, 2013) and lead to undesirable environmental impacts, such as pollution of surface and subsurface waters (Carneiro et al, 2012;Sørensen & RubAEk, 2012;Sweeney et al, 2012).…”

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.

“…Kunz and Oliveira (2008) stated that the goal of biodigestors in Brazil is: the treatment of effluents, use of biogas as an energy alternative, and the use of effluent to improve soil fertility. The use of these effluents to recover water and improve fertility was also an objective described by Leal et al (2010) and Bócoli et al (2016). Silva (2012) concluded that biodigestion of human and swine waste was feasible, reducing BOD, COD and coliform levels; however, the treated effluent cannot be directly discharged in water bodies, without prior clearance.…”

Environmentally friendly options for waste disposal and the need for expansion and diversification of the national and international energy matrix are relevant issues today. One technique that supports these goals is anaerobic biodigestion, which generates clean energy from biomass. Accordingly, our goal was to perform a quantitative and qualitative assessment of scientific publications on biodigestion in order to understand the evolution of the technique, which is essential for environmental and economic sustainability. Ninety-nine articles indexed in the Scientific Electronic Library Online between 1980 and 2015 were evaluated. The results showed a significant increase in scientific publications since 2000 which addressed, in addition to environmentally friendly waste management, the energy issue, with the use of biogas. This increase in the number of publications coincides with increased awareness on natural resource management and concern about global energy management. Most of the articles involved a general evaluation of the process, using mainly animal waste from pigs, and emphasizing biodigestion as waste management, since pig farming produces a large volume of waste and has a high environmental impact.Keywords: anaerobic fermentation, biogas, energy, brazilian scientific publications, waste management. Gestão energética: uma síntese dos indicadores quantitativos sobre biodigestão RESUMOOpções ambientalmente corretas de destinação de resíduos e a necessidade de ampliação e diversificação da matriz energética nacional e internacional são assuntos pertinentes na atualidade. Uma das técnicas capaz de atender estas premissas é a biodigestão anaeróbica, que gera energia limpa a partir de biomassa. Desta forma, o objetivo deste trabalho foi realizar uma avaliação quanti e qualitativa sobre o tema biodigestão, entendendo o comportamento científico das publicações sobre esta técnica, fundamental para a sustentabilidade ambiental e econômica. nas publicações científicas a partir de 2000, que abordavam, além da gestão de resíduos ambientalmente correta, a questão energética, com o uso do biogás. Este aumento nas publicações coincide com a maior conscientização acerca dos cuidados com os recursos naturais e a preocupação com a gestão energética mundial. A maioria dos artigos discutiu sobre a avaliação geral do processo, empregando dejetos animais, principalmente de suínos, enfatizando a biodigestão como gestão de resíduos, visto que a suinocultura gera um grande volume de dejetos e ocasiona elevado impacto ambiental.Palavras-chave: biogás, energia, fermentação aneróbica, manejo de dejetos, publicações científicas brasileiras.
