| Los beneficios de la aplicación de enmiendas orgánicas en la agricultura son conocidos a nivel mundial; sin embargo, existen muy pocos estudios sobre los contenidos nutricionales y actividad biológica de estos fertilizantes orgánicos. En República Dominicana estas enmiendas son aplicadas en la agricultura hace más de dos décadas; pero no han sido estudiadas. El objetivo de la investigación fue determinar las características física-químicas y microbiológicas de las enmiendas orgánicas de mayor uso en República Dominicana, así como las fuentes utilizadas para su preparación. Las muestras de enmiendas orgánicas fueron recolectadas en las localidades de Jarabacoa, Espaillat, La Vega y Montecristi durante el periodo enero del 2005 a julio 2006. En total se... |

| Sewage sludge (SS) has been widely used as organic fertilizer. However, its continuous use can cause imbalances in soil fertility as well as soil-water-plant system contamination. The study aimed to evaluate possible improvements in the chemical and microbiological characteristics of domestic SS, with low heavy metal contents and pathogens, through the composting process. Two composting piles were set up, based on an initial C/N ratio of 30:1, with successive layers of tree pruning waste and SS. The aeration of piles was performed by mechanical turnover when the temperature rose above 65 ºC. The piles were irrigated when the water content was less than 50 %. Composting was conducted for 120 days. Temperature, moisture content, pH, electrical conductivity... |

| Composting has the potential to mitigate methane (CH4) and nitrous oxide (N2O) emissions from manure. The heterogeneous nature of emitting surfaces makes it difficult to quantify these emissions. CH4 and N2O fluxes measured using eight small chambers (0.72 m2) and a mega chamber (90 m2) were compared, and the effect of aeration on the fluxes during composting was studied. Two batches of compost were placed in three channels and 2-3 small flux chambers were deployed on each channel. The channels were enclosed by a building serving as a mega chamber. Chamber location significantly affected gas fluxes, pointing to strong spatial heterogeneity. Mean CH4 fluxes from the small chambers were similar or 1.4 times higher compared to the mega chamber. Mean... |

| Compression is important to prevent a deterioration in quality pellets for long term storage and the moisture content of the pellets must be reduced to or less. In this research the quality of pellet of compost was studied at air temperatures of 50, 60 and 70, air velocities of 0.5, 1, and 1.5 m/s, particle sizes of 16(1.18mm) and 10(2mm) and pellet diameters of 6 and 8 mm. The Taguchi quality engineering method was used to investigate the effects of parameters on compressive strength of pellet. An orthogonal array, signal-to-noise (S/N) ratio analysis of variance (ANOVA) were employed to analyze the effect of these compressive strength parameters. Thus, the optimal performance for the compressive strength of pellet was obtained at first level of factor... |

| ABSTRACT During composting processes, the degradation of organic waste is accomplished and driven by a succession of microbial populations exhibiting a broad range of functional competencies. A total of 183 bacteria, isolated from a composting process, were evaluated for cellulase activity at different temperatures (37, 50, 60, and 70°C) and pH values. Out of the 22 isolates that showed activity, isolate 380 showed the highest cellulase activity. Its ability to produce cellulase was evaluated in culture medium supplemented with carboxymethyl cellulose, microcrystalline cellulose, wheat straw, and rice husk. The culture medium supplemented with carboxymethyl cellulose induced higher enzyme activity after 6 hours of incubation (0.12 UEA mL-1 min-1). For... |

| Livestock manure may contain pathogenic microorganisms which pose a risk to the health of animal or humans if the manure is not adequately treated or disposed of. To determine the fate of Shiga toxigenic Escherichia coli (STEC) non O157 in composted manure from naturally colonized sheep, fresh manure was obtained from animals carrying bacterial cells with stx1/ stx2 genes. Two composting systems were used, aerated and non-aerated, and the experiments were done in Dracena city, São Paulo State. Every week, for seven weeks, one manure sample from six different points in both systems was collected and cultured to determine the presence of E. coli, the presence of the virulence genes in the cells, and also the susceptibility to 10 antimicrobial drugs. The... |

| ABSTRACT VC (20%), TC (20%) and N:P:K fertilizer (farmer's practice) were used to determine the growth and yield attributes of bush bean (Phaseolus vulgaris), winged bean (Psophocarpus tetragonolobus) and yard long bean (Vigna unguiculata). Plants grown with VC (20%) produced the highest fresh biomass for bush bean (527.55 g m-2), winged bean (1168.61 g m-2) and yard long bean (409.84 g m-2). In all the tested legumes the highest pod weight, pod number, pod dry weight and pod length were found in the VC (20%) treatment. Photosynthetic rates in the three legumes peaked at pod formation stage in all treatments, with the highest photosynthetic rate observed in winged bean (56.17 µmol m-2s-1) grown with VC (20%). The highest yield for bush bean (2.98 ton... |

| Under semiarid conditions the response of cereal crops to chemical fertilizers and weed control practices with herbicides is often reduced. In fact, the economic profitability of agricultural production in many dryland regions is critically affected by high costs of inputs and low crop yields. As a solution, cropping systems like organic farming, obtaining similar yields and promoting environmental sustainability by reducing fertilizer and herbicides, could be an alternative to conventional systems. In this study, 23 trials were performed in five semiarid regions of Spain during 5 yr to compare different fertilizers and weed control methods on durum wheat (Triticum durum Desf.) and barley (Hordeum vulgare L.) yields. The following rotation pattern was... |
