Lodo de esgoto compostado na produção de tapetes de grama esmeralda e na manutenção de água no solo /

Mota, Flávia Diniz, 1982. January 2016 (has links)
Orientador: Roberto Lyra Villas Bôas / Banca: Caroline de Moura D'Andréa Mateus / Banca: Hélio Grassi Filho / Resumo: O lodo de esgoto, resíduo de maior volume gerado durante os processos de tratamento de efluentes domésticos, apresenta disposição final problemática, inviabilizando seu uso direto na agricultura. Porém, legalmente, surgiu a possibilidade de misturar o lodo de esgoto com uma fonte de carbono, gerando o composto a base de lodo de esgoto, viabilizando seu uso na agricultura. Objetivou-se com esse trabalho avaliar o uso de lodo de esgoto compostado na produção de tapetes de grama esmeralda e sua influência na manutenção de água no solo. O experimento foi instalado em uma propriedade de produção de grama, localizada em Itapetininga-SP. A cultura utilizada foi a grama Zoysia japonica Steud. conhecida como grama esmeralda. O delineamento experimental utilizado foi o de blocos ao acaso, com doze tratamentos e cinco repetições. Os tratamentos foram definidos por cinco doses de lodo de esgoto compostado (0,10, 20, 30 e 40 Mg ha-1, base seca), uma dose de adubo inorgânico e duas formas de aplicações (aplicação única e parcelada do composto). Utilizou-se o lodo de esgoto compostado da Estação de Tratamento de Esgoto da cidade de Jundiaí. As doses aplicadas correspondem às doses de 100, 200, 300 e 400 kg ha-1 de nitrogênio. Observou-se ... / Abstract: The sewage sludge, major waste volume generated during treatment processes of domestic effluents shows a problematic final disposal, impairing its direct use in agriculture. Although another legally possibility have emerged, which is the sludge and a carbon source mixing, generating a compound based in sewage sludge, enabling its use in agriculture. The aim of this work was evaluate compounded sewage sludge doses maintain water in soil in the zoysiagrass sod production. The experiment was installed grass grower property locates in Itapetininga, São Paulo. The used crop was the Zoysia japonica Steud, known as "Esmeralda". The experimental delineation used in the work was the randomized blocks one, with twelve treatments and five repetitions. The treatments were defined by five compound sludge doses (0, 10, 20, 30 and 40 Mg ha-1, dry base), an inorganic fertilizer dose and two applications (compound unique and parceled application). It was used the sewage sludge compounded from the Sewage Treatment Station of Jundiai County. The rates applied correspond to 100, 200, 300 and 400 kg ha-1 of nitrogen. It can be concluded that the 212 days after the compound application, the 30 Mg ha-1 rate allowed the complete formation of the sod (100% cover rate). It was verified that happened a weight loss in zoysiagrass sod with the applied compounded sewage sludge doses raising, and resistance raising for 30 Mg ha-1 doses. The control and plots which received doses of 10 Mg ha-1 have not formed sod. There were no losses and all sod were good using the rates of 30 and 40 Mg ha-1. There was a reduction of 8% in the weight of sod that received 40 Mg ha-1 rate compared to 30 Mg ha-1 rate, and 10% compared to chemical fertilizer. The 30 Mg ha-1 rate showed the best sod strength and formation. Control and plots that received 10 Mg ha-1 rates did not form sod. In the 30 and 40 Mg ha-1 rates, 100% of the sod showed ... / Mestre
