Bacterial biodiversity from an anaerobic up flow bioreactor with ANAMMOX activity inoculated with swine sludge BABT
Viancelli,Aline; Kunz,Airton; Esteves,Paulo Augusto; Bauermann,Fernando Viçosa; Furukawa,Kenji; Fujii,Takao; Antônio,Regina Vasconcellos; Vanotti,Matias.
The present study aimed to describe the bacterial community present at an anaerobic up flow bioreactor with ANAMMOX activity, inoculated with the sludge from the anaerobic pond of a swine slurry treatment system. The description was based on the molecular DNA techniques using primers for amplification of complete 16S rRNA gene and also new primers to amplify smaller fragments from 16S rRNA. During the bioreactor operation time, the bacterial community changed significantly, increasing the nitrogen removal efficiency, reaching after 500 days a removal rate of 94%. The complete PCR amplification of 16S rRNA gene generated 17 clones, where three presented similarity with Candidatus Jettenia asiatica (97%), twelve with Janthinobacterium (99%) and two with...

Effect of digester surface area on biogas yield CIGR Journal
Ogunwande, Gbolabo Abidemi.
Poultry manure, cow dung and swine manure were digested in cube-shaped anaerobic digesters of equal volume but different surface areas (SAs) (5.38, 10.0 and 11.6 dm2) in a two-factor experiment. The digesters were agitated once a day during the experiment. The results showed that neither the manure type nor SA affected (p > 0.05) substrate temperature and pH, but both had (p ≤ 0.05) on biogas yield (BY. Poultry manure had the highest BY followed by swine manure and cow dung (1.00, 0.59 and 0.11 dm3 kg-1 VS fed day-1, respectively). Within the SAs investigated, BY increased as digester SA increased (0.27, 0.68 and 0.74 dm3 kg-1 VS fed day-1 for 5.38, 10.0 and 11.6 dm2, respectively). The results of the regression analysis showed that digester diameter to...

Nitrate leaching from a Latosol after application of liquid swine manures in different pH values and organic matter contents - doi: 10.4025/actasciagron.v32i4.10070 Agronomy
Costa, Antonio Carlos Saraiva Da; Universidade Estadual de Maringá; Seidel, Edleusa Pereira; Universidade Estadual do Oeste do Paraná.
Liquid swine manures are produced in large volumes in the western Paraná and Santa Catarina states and are reused as a source of nutrients. This study aimed to evaluate the losses of nitrate (N-NO3-1) after application of liquid swine manures in three samples of a Latosol (Rhodic Eutrudox) with different levels of soil organic matter and pH collected at different depths. The experimental design was completely randomized with one soil, three levels of soil organic matter (34.09, 22.36 and 8.6 g dm-3), four pH in CaCl2 (4.0, 5.0, 6.0 and 7.0) conditions and three replications. Each experimental unit contained 450 cm3 of soil that received a dose of liquid swine manures equivalent to 120,000 dm-3 ha-1. The concentration of N-NO3-1 was evaluated in the...

Potential of biogas production from swine manure supplemented with glycerine waste REA
Konrad,Odorico; Koch,Fabio F.; Lumi,Marluce; Tonetto,Jaqueline F.; Bezama,Alberto.
In this study, was studied the biogas generation from swine manure, using residual glycerine supplementation. The biogas production by digestion occurred in the anaerobic batch system under mesophilic conditions (35°C), with a hydraulic retention time of 48 days. The experiment was performed with 48 samples divided into four groups, from these, one was kept as a control (without glycerin) and the other three groups were respectively supplemented with residual glycerine in the percentage of 3%, 6% and 9% of the total volume of the samples. The volume of biogas was controlled by an automated system for reading in laboratory scale and the quality of the biogas (CH4) measured from a specific sensor. The results showed that the residual glycerine has high...

Recycling of nutrients with application of organic waste in degraded pasture REA
Silva,Adriane de A.; Costa,Adriana M. da; Lana,Regina M. Q.; Lana,Ângela M. Q..
The utilization of organic wastes represents an alternative to recover degraded pasture. The experiment aimed to assess the changes caused by the provision of different organic waste (poultry litter, turkey litter and pig manure) in a medium-textured Oxisol in Brazilian Savanna under degraded pasture. It was applied different doses of waste compared to the use of mineral fertilizers and organic mineral and evaluated the effect on soil parameters (pH, organic matter, phosphorus and potassium) and leaf of Brachiariadecumbens (crude protein, phosphorus and dry mass production). It was observed that application of organic waste did not increase the level of soil organic matter and pH in the surface layer, and the application of turkey litter caused...

Soil carbon and nitrogen mineralization caused by pig slurry application under different soil tillage systems PAB
Balota,Elcio Liborio; Machineski,Oswaldo; Truber,Priscila Viviane.
The objective of this work was to evaluate the change in soil C and N mineralization due to successive pig slurry application under conventional tillage (CT) and no tillage (NT) systems. The experiment was carried out in a clayey Latossolo Vermelho eutrófico (Rhodic Eutrudox) in Palotina, PR, Brazil. Increasing doses of pig slurry (0, 30, 60 and 120 m³ ha-1 per year) were applied in both tillage systems, with three replicates. Half of the pig slurry was applied before summer soil preparation, and the other half before the winter crop season. The areas were cultivated with soybean (Glycine max L.) and maize (Zea mays L.) in the summers of 1998 and 1999, respectively, and with wheat (Triticum sativum Lam.) in the winters of both years. Soil samples were...

Balota,Elcio L.; Machineski,Oswaldo; Matos,Maria A..
ABSTRACT The objective of this work was to evaluate the changes in microbial biomass C, N and P due to the application of pig slurry under different soil tillage systems. The experiment was established in a clayey Oxisol, Eutrophic Red Latossol in Palotina, PR. Different quantities of pig slurry (0, 30, 60 and 120 m3 ha-1 year-1) were applied to the soil prior to the summer and winter crop season under conventional tillage (CT) and no tillage (NT), in three replicates. The area was cultivated with soybean (Glycine max L.) or maize (Zea mays L.) in the summer and wheat (Triticum sativum Lam.) or oat (Avena sativa L.) in the winter. The soil samples were collected in March and October of 1998 and 1999 at depths of 0-5, 5-10 and 10-20 cm. The soil tillage and...

SOIL PHOSPHORUS THRESHOLDS IN EVALUATING RISK OF ENVIRONMENTAL TRANSFER TO SURFACE WATERS IN SANTA CATARINA, BRAZIL Rev. Bras. Ciênc. Solo
Gatiboni,Luciano Colpo; Smyth,Thomas Jot; Schmitt,Djalma Eugenio; Cassol,Paulo Cezar; Oliveira,Clovisson Menotti Boeira de.
The State of Santa Catarina, Brazil, has agricultural and livestock activities, such as pig farming, that are responsible for adding large amounts of phosphorus (P) to soils. However, a method is required to evaluate the environmental risk of these high soil P levels. One possible method for evaluating the environmental risk of P fertilization, whether organic or mineral, is to establish threshold levels of soil available P, measured by Mehlich-1 extractions, below which there is not a high risk of P transfer from the soil to surface waters. However, the Mehlich-1 extractant is sensitive to soil clay content, and that factor should be considered when establishing such P-thresholds. The objective of this study was to determine P-thresholds using the...
