The objective of this work was to evaluate the microbiological and chemical attributes of a soil with a seven‑year history of urea and swine manure application. In the period from October 2008 to October 2009, soil samples were collected in the 0-10 cm layer and were subjected to the treatments: control, without application of urea or manure; and with the application of urea, pig slurry, and deep pig litter in two doses, in order to supply one or two times the recommended N doses for the maize (Zea mays)/black oat (Avena strigosa) crop succession. The carbon of the microbial biomass (MB‑C) and the basal respiration (C‑CO2) were analyzed, and the metabolic (qCO2) and microbial quotient (qmic) were calculated with the obtained data. Organic matter, pH in...

Successive applications of pig litter to the soil surface can increase the phosphorus (P) content and alter its adsorption, promoting P transfer to surface or subsurface waters. The purpose of this study was to evaluate P accumulation and the pollution potential of a soil after application of pig litter. In March 2010, eight years after the installation of an experiment in Braço do Norte, Santa Catarina, SC, Brazil, on a Typic Hapludult, soil was sampled (layers 0-2.5, 2.5-5, 5-10, 10-15, 15-20 and 20-30 cm) after the following fertilization treatments: no pig litter fertilization, pig slurry application and pig manure application. In this period, 694 and 1,890 kg P2O5 ha-1 were applied in the treatments with pig slurry and pig manure, respectively. The P...

Avaliação de sistema de tratamento de dejetos suínos instalado no estado de Santa Catarina
Provedor de dados: 91
Autores: Araújo,Iria S.; Oliveira,José L. R.; Alves,Rui G. C. M.; Belli Filho,Paulo; Costa,Rejane H. R. da.
Os dejetos suínos contribuem de forma significativa em prol da degradação dos recursos naturais e para a diminuição da qualidade de vida na região sul do estado de Santa Catarina, Brasil. O excesso de dejetos gerados pelo grande número dos suínos por unidade de área dificulta a solução do problema. Este trabalho teve como objetivo avaliar o comportamento de um sistema de tratamento de dejetos suínos, em série e em escala real, composto de unidades anaeróbias, unidades aeróbias e pós-tratamento. Os parâmetros analisados foram: DBO, DQO, PT, P-PO4, N-NH3, NTK, pH, clorofila a, biomassa algal, coliformes totais e coliformes fecais (Escherichia coli). O sistema mostrou que após um ano de funcionamento as eficiências de remoção foram satisfatórias para matéria...

Tecnologias para o tratamento de dejetos de suínos
Provedor de dados: 91
Autores: Belli Filho,Paulo; Castilhos Jr.,Armando B. de; Costa,Rejane H.R. da; Soares,Sebastião R.; Perdomo,Carlos C.
Com este trabalho apresentaram-se os problemas ambientais provenientes da suinocultura no Sul do Brasil, as formas adotadas de criação dos animais e suas relações econômicas, sociais e ambientais. No Estado de Santa Catarina concentra-se o maior rebanho nacional, da ordem de 4,5 milhões de cabeças, gerando aproximadamente 150.000 empregos diretos, possuindo 25.000 propriedades produtoras de animais. Em termos ambientais, a suinocultura é um setor com baixa qualidade ambiental, pois apenas 15% das propriedades dispõem, de alguma forma, de manejo de dejetos. Com o objetivo de contribuir na busca da qualidade ambiental para este setor, apresentam-se orientações tecnológicas, definidas a partir de resultados de pesquisas, com metodologias para reduzir a...

Copper and zinc fractions in the profile of an Inceptisol cultivated with apple in southern Brazil

ABSTRACT The present study aimed to evaluate the accumulation and distribution of Cu and Zn fractions in the profile of an Inceptisol by application of fungicides with a previous history of apple cultivation in southern Brazil. Stratified soil samples (0.0 – 0.025 m, 0.025 –0.050 m, 0.05 – 0.10 m, 0.10 – 0.15 m, 0.15 – 0.20 m and 0.20 – 0.40 m depth) were collected in two apple orchards (8 years old and 18 years old), and in a native pasture area adjacent to the orchards. The soil was subjected to analysis of physical and chemical properties and to chemical fractionation of Cu and Zn. The fractions of soluble, exchangeable, organic, residual and total Cu and Zn accumulated in the topsoil (0.0 – 0.025 m) of the orchards, being higher in the orchard...

Aeration frequency on accelerated composting of animal carcasses
Provedor de dados: 64
Autores: Oliveira,Matias Marchesan de; Coldebella,Arlei; Belli Filho,Paulo; Oliveira,Paulo Armando Victória de.
ABSTRACT Rotary drum reactors (RDRs) for accelerated carcass composting are being installed in animal production units as an alternative for the disposal of pig and poultry carcasses in Brazil. The aim of the present study was to investigate the influence of aeration frequency on gas emissions (CO2-C, CH4-C, NH3-N and N2O-N) during composting of pig and poultry carcasses in RDRs. RDRs with a volume of 3.6 m3 (50% useful volume) were used. Aeration time was 24 minutes. Four intervals between aeration periods were tested (treatments) as follows: 1 hour (T1), 2 hours (T2), 3 hours (T3) and 4 hours (T4). Gas emissions were continuously monitored using a photoacoustic gas monitor (INNOVA 1412). Temperature was monitored using iButtons mixed with the biomass....
