Diante disso, o objetivo deste trabalho foi caracterizar os par?metros f?sico-qu?micos de dejetos l?quidos de su?nos (DLS), tratados em sistema de lagoas em s?rie e avaliar as altera??es nos atributos microbiol?gicos de um solo cultivado com caf? ap?s aplica??o de diferentes doses de DLS. O estudo foi conduzido na Granja Campo Alegre e na Fazenda Yamaguchi, no Munic?pio de Diamantina, Minas Gerais. Os DLS foram coletados em v?rios pontos: sa?da das instala??es, sa?da da lagoa anaer?bia, sa?da da primeira lagoa facultativa e sa?da da segunda lagoa facultativa, sendo analisados: Demanda Qu?mica de Oxig?nio (DQOt), Demanda Bioqu?mica de Oxig?nio (DBO5), Concentra??o de S?lidos Totais (ST), Nitrog?nio Total (N-Total), F?sforo, Pot?ssio, Zinco e Cobre. Ap?s an?lise, os dejetos foram aplicados em um cafeeiro, em experimento, constitu?do por cinco tratamentos com cinco repeti??es. As amostras de solo foram coletadas, na camada de 0-10 cm, de profundidade. Foram avaliados a respira??o basal, o carbono da biomassa microbiana e determinado o quociente metab?lico. Os resultados permitiram constatar que o sistema de lagoas de estabiliza??o em s?rie apresenta 88% de efici?ncia na remo??o de DQOt e 91% na remo??o de DBO5. As fra??es de s?lidos apresentaram comportamento semelhante e a efici?ncia de remo??o de N-Total correspondeu a 24,2%. O uso de dejetos l?quidos de su?nos no solo, antes e 30 dias ap?s sua aplica??o, aumentou a biomassa microbiana do solo e a atividade microbiana. Os resultados obtidos permitem concluir que o sistema de lagoas de estabiliza??o em s?rie demonstra ser eficiente na remo??o do excesso de nutrientes. Ressalte-se que o tratamento demonstrou caracter?sticas favor?veis ao reaproveitamento dos dejetos como biofertilizante. / Disserta??o (Mestrado) ?

Therefore, the objective of this study was to characterize the physical and chemical parameters of pig slurry (DLS), treated in a system of ponds in series and evaluate the changes in the microbial soil of a coffee plantation after applying different doses of pig slurry. The study was conducted in the Campo Alegre Farm and Ranch Yamaguchi in the city of Diamantina, Minas Gerais. The DLS were collected at various points: exit of the facilities, exit of the anaerobic pond, exit of the first facultative pond, exit of the second facultative pond, and analyzed: Chemical Oxygen Demand (DQOt), Biochemical Oxygen Demand (BOD5) concentration Total Solids (DS), Total Nitrogen (Total-N), Phosphorus, Potassium, Zinc, and Copper. After analysis, the pig manure were applied in a coffee plantation, in an experiment consisting of five treatments with five replications. Soil samples were collected at 0-10 cm depth. It was evaluated the basal respiration, microbial biomass carbon and metabolic quotient determined. The results show that the system of stabilization ponds in series features 88% efficiency in removing DQOt and 91% for BOD5 removal. The fractions of solids showed similar behavior and t removal efficiency of Total-N accounted for 24.2%. Use of pig slurry in soil, before and 30 days after application, amplified the soil microbial biomass and microbial activity. The results showed that the system of stabilization ponds in series proves to be effective in removing excess nutrients. It is noteworthy that treatment showed favorable characteristics for reuse of wastes as biofertilizers.

Em Diamantina, esse pedoambiente ? encontrado na ?rea de Prote??o Ambiental - APA Pau-de-Fruta, situada a 6 km da sede do munic?pio, a uma altitude m?dia de 1366 m. A APA est? inserida na Serra do Espinha?o Meridional, sua litologia ? predominantemente quartz?tica e a vegeta??o ? t?pica de campo rupestre, com pequenas ilhas de cerrado denominadas cap?es, que se adaptaram ao ambiente hidrom?rfico. O ambiente ? oligotr?fico e apresenta elevados teores de Al3+ e valores de satura??o por alum?nio. As turfeiras formadas nessa ?rea apresentam verticalmente uma estrutura bem definida, sendo que as camadas mais superficiais foram classificadas, de acordo com seu est?gio de decomposi??o, como f?bricas, as intermedi?rias como h?micas e as camadas mais profundas, como s?pricas. A turfeira, por ser um ambiente de ac?mulo de mat?ria org?nica em condi??es de baixa atividade de O2, favorece a forma??o e a manuten??o de subst?ncias h?micas, sobretudo as fra??es menos sol?veis, de forma que o teor de humina ? maior que os teores de ?cidos h?micos que, por sua vez, s?o maiores que o teor de ?cidos f?lvicos. A turfeira, devido ao seu comportamento tipo esponja, apresenta grande import?ncia na din?mica da ?gua nessa regi?o, de forma que, nos per?odos chuvosos, ela armazena ?gua em seus poros e a libera de forma gradativa com o passar do tempo. A turfeira da APA Pau-de-Fruta ocupa 81,75 ha, armazena cerca de 629.782 m3 de ?gua e estoca em torno de 33.129 toneladas de carbono. Dessa forma, a turfeira da APA Pau-de-Fruta representa um consider?vel reservat?rio natural de ?gua, bem como o importante ambiente de sequestro de carbono e ? fundamental para o abastecimento de ?gua da cidade de Diamantina. / Disserta??o (Mestrado) ?

In Diamantina, this is found in the Environmental Protection Area - EPA Pau-de-Fruta, situated 6 km from the headquarters of the city, at an average altitude of 1,366 m. The EPA is inserted in the Serra do Espinha?o Meridional, its lithology is predominantly quartz and its vegetation is typical of rocky field, with small islands of ?cerrado? (vegetation of the Brazilian interior) called ?cap?es?, which are adapted to the hydromorphic environment. The environment is oligotrophic and offers high levels of Al3+ and the values of saturation by aluminum. The bogs formed in this area have a vertically well-defined structure and, according to their stage of decomposition, the more superficial layers were classified as ?f?bricas?, the intermediate layers as ?h?micas?, and the deeper layers as ?s?pricas?. The bog, being an environment of accumulation of organic material under conditions of low activity of O2, promotes the formation and maintenance of wet substances, especially the less soluble fractions, so that the content of humin is greater than the levels of humic acids which in turn are greater than the content of fulvic acids. The bog, because of its behavior type sponge, has great importance in the dynamics of water in this region, so that in rainy periods it stores water in its pores and releases it gradually over the time. The bog of the EAP Pau-de-Fruta occupies 81.75 ha, stores about 629,782 m3 of water and stocks around 33,129 tonnes of carbon. Thus, the bog of of the EAP Pau-de-Fruta is a considerable natural reservoir of water, and an important environment of carbon sequestration and it is essential for the supply of water for the city of Diamantina.
