Incorporação de lodo de esgoto e seus efeitos sobre alguns atributos do solo cultivado com rabanete (raphanus sativus l.) / Incorporation of sewage sludge and its effects on some attributes of soil cultivated with radish (Raphanus sativus L.)

Maria dos Anjos de Jesus Barros Monteiro Lopes 17 July 2008 (has links)
O lançamento de poluentes no ambiente tem estado sobre severo controle nos países desenvolvidos e vem crescendo a importância dada ao problema nos países em desenvolvimento, como o Brasil e Cabo Verde. Uma alternativa viável para a destinação de resíduos é a sua aplicação na agricultura, como recondicionante do solo, podendo se tornar relevante do ponto de vista econômico e ambiental. O presente estudo teve como objetivo avaliar os efeitos causados pelo uso do lodo de esgoto em solo cultivado com rabanete (Raphanus sativus L.). O trabalho foi conduzido em área experimental situada na Comunidade Famílias Unidas, no bairro de Santa Mônica, município de Camaragibe, Pernambuco, Brasil, em solo ARGISSOLO VERMELHO Distrófico. O delineamento experimental utilizado foi o de blocos casualizados, com cinco tratamentos (zero, 25, 50 e 75 Mg ha-1 de lodo de esgoto mais 25 Mg ha-1 de lodo de esgoto vermicompostado com a Vermelha da Califórnia Eisenia foetida) e três repetições. Os canteiros de alvenaria mediram 1 m de largura por 6 m de comprimento e 0,20 m de profundidade, com 21 fileiras espaçadas de 0,35 m entre fileiras e 0,15 m entre plantas. A colheita do rabanete foi realizada 30 dias após semeadura, observando-se, após análise estatística, uma produção em torno de 18 t/ha na dose equivalente a 25 Mg ha-1 de lodo de esgoto. Os demais parâmetros analisados também responderam de acordo com os limites da legislação à presença do lodo de esgoto / The release of pollutants in the environment has been under severe control in developed countries. In developing countries like Brazil and Cabo Verde this control has also been increasing. A viable alternative for the purpose of this waste is its application in agriculture as reconditionant soil, thus becoming important from the economic and environmental points of view. This study aimed to evaluate the effects caused by the use of sewage sludge on land cultivated with radish (Raphanus sativus L.). The work was conducted in an experimental area located in the United Families Community, in the district of Santa Monica, City of Camaragibe, Pernambuco, Brazil, using Dystrophic RED ARGISOIL soil. A randomized block experimental design with five treatments (zero, 25, 50 and 75 Mg ha-1 of sewage sludge and 25 Mg ha-1 of humus California red - Eisenia foetida) and three repetitions was used. The masonry plots measured 1 m wide, 6 m long and 0.20 m deep, with 21 rows spaced between rows of 0.35 m and 0.15 m between plants. The harvest of the radish was held 30 days after sowing. It was observed, after statistical analysis, a production of around 18 t / ha in the dose equivalent to 25 Mg ha-1 of sewage sludge. The other examined parameters had also a positive behaviour in the presence of sewage sludge
