| This study aimed to quantify the carbon dioxide emissions from an Oxisol under degraded pasture located in Sorocaba, São Paulo State, Brazil. The treatments were: sewage sludge (LE), sewage sludge compost (CLE), mineral fertilizer (AM) and no fertilization (T0). The experiment was conducted in a completely randomized block design with analysis of the effect of the four treatments (CLE, LE, and AM T0) with four replications. The application of sewage sludge, sewage sludge compost, mineral fertilizer and no fertilizer was statistically significant for the variables of height increase and stem height of Guanandi seedlings (Calophyllum brasiliense Cambessèdes - Calophyllaceae). Treatments showed significant differences in terms of CO2 emissions from soil. The... |

| Resumo: Objetivou-se avaliar a influência de dietas formuladas com diferentes proporções de volumoso:concentrado (V:C) sobre o consumo de matéria seca, consumo alimentar residual, volume globular no sangue, ovos por grama de fezes (OPG), e dados de emissão de metano em cordeiros infectados artificialmente com Haemonchus contortus. O delineamento utilizado foi inteiramente casualizado, em esquema fatorial 4 x 2 (quatro dietas 70:30, 66:34, 43:57, 36:54 de proporção V:C), infectados ou não com Haemonchus contortus. Foram utilizados 32 cordeiros machos, com peso inicial médio de 26,6 kg e cinco meses de idade. Os dados foram submetidos à análise estatística e as médias dos dados comparadas pelo teste Tukey, em nível de 5% de significância. O incremento nas... |

| ABSTRACT The objective of this study was to compare the emissions of nitrous oxide (N2O) resulting from the application of nitrogen (N) and potassium (K) doses in fertigated sugarcane, in comparison to emissions from conventional fertilizer application. The study was conducted in the experimental area of Embrapa Mid-North, Teresina, Piauí state, Brazil, from August 2014 to January 2015. The experimental design was in randomized blocks, analyzed in a (2 x 2) +1 factorial scheme, with four replicates. The treatments consisted of the combination of two doses of N and K2O (60-120 and 120-180 kg ha-1, respectively) and two methods of application (in soil and fertigation), and a control. The use of fertigation reduced the emissions of N2O in sugarcane compared... |
