Previous issue date: 2014-07-17 / CAPES / The city of Rio Verde-GO has excelled for having important agro-industrial units with important breeding of cattle, poultry and pigs. The swine farms handle the liquid waste stabilization ponds with or without digesters systems, accumulating them for 2 months to 4 months, and then applied in areas of approximately 100 to 300 acres. Floating gas collection chambers, where the samples are captured biogas emitted to the atmosphere of stabilization ponds and then analyzed the samples in the laboratory of Embrapa Agrobiology were installed, in addition, to conduct sampling of swine manure (DLS) itself to quantification of elements present in it. It was found in this study that the largest emissions of methane (CH4) were in the following descending order of magnitude: 205.3 ? 68.79 Mg CH4 yr-1 for the fattening farm without biodigester (4,000 swines); 123.94 ? 39.17 Mg CH4 yr-1 in the fattening farm with a biodigester (4,000 swines); 11.22 ? 3.0 ton CH4 year-1 for the producing piglets farm with a biodigester (1,008 matrices swines) and 2.75 ? 0.89 Mg CH4 yr-1 in the producing piglets farm with two biodigesters (728 matrices swines), thus proving expected to their farms in production. Interaction in methane (CH4 Mg yr-1) and concentration (mg L-1) macronutrients (N, P and K) present in the DLS was observed for nitrogen (Ntotal) a linear equation y = 0.1797x ? 111.81 (R2 0.9844); for phosphorus (P) is the linear equation y = 1.4905x ? 25.224 (R2 0.9436); whereas for potassium (K) a linear equation y = 0.0693 ? 35.934 (R2 0.9337). / A cidade de Rio Verde-GO tem se destacado por contar com importantes unidades agroindustriais com importante plantel de bovinos, av?cola e de su?nos. As granjas de su?nos manejam os res?duos l?quidos em sistemas de lagoas de estabiliza??o com ou sem biodigestores, acumulando-os durante 2 meses a 4 meses, sendo ent?o aplicados em ?reas de aproximadamente 100 a 300 hectares. Foram instaladas c?maras flutuantes de coleta de gases, onde foram capturadas as amostras do biog?s emitido para atmosfera das lagoas de estabiliza??o e ent?o analisadas as amostras no laborat?rio da Embrapa Agrobiologia, al?m, da realiza??o de coletas de amostras do pr?prio dejeto l?quido de su?no (DLS) para quantifica??o dos elementos presentes no mesmo. Verificou-se na presente pesquisa que as maiores emiss?es de metano (CH4) ocorreram na seguinte ordem de grandeza decrescente: 205,3 ? 68,79 Mg CH4 ano-1 para a granja em termina??o sem biodigestor (4.000 su?nos); 123,94 ? 39,17 Mg CH4 ano-1 na granja de termina??o com um biodigestor (4.000 su?nos); 11,22 ? 3,0 Mg CH4 ano-1para a granja de produ??o de leit?es com um biodigestor (1.008 matrizes em produ??o) e 2,75 ? 0,89 Mg CH4 ano-1 na granja de produ??o de leit?es com dois biodigestores (728 matrizes em produ??o), comprovando assim o esperado para as respectivas granjas em produ??o. Na intera??o das emiss?es de metano (Mg CH4 ano-1) e a concentra??o (mg L-1) de macronutrientes (N, P e K) presentes nos DLS observou-se para o nitrog?nio (NTotal) uma equa??o linear ? = 0,1797? ? 111,81 (R2 de 0,9844); em rela??o ao f?sforo (P) esta equa??o linear ? = 1,4905? ? 25,224 (R2 de 0,9436); enquanto que para o pot?ssio (K) uma equa??o linear ? = 0,0693? ? 35,934 (R2 de 0,9337).
