    • Abstract:
      The objective of this experiment was to evaluate the susceptibility of different conventional drip irrigation system to clogging by iron soluble in irrigation water (ferrous sulfate) via two water qualities (with and without organic load), suspended solids (soil) and concentrated solution, with the imitter of the dripline positioned down. The experiment was conducted during the period of 12 months, with 7 models dripline. The tests were performed on a test bench in metal structure located in the Irrigation Laboratory of the College of Agriculture "Luiz de Queiroz" - ESALQ/USP. The application of soil particles and high iron content without going through filtering intensified clogging process. The models B, F and G showed complete clogging from the 1296, 792 and 1152 hours of operation. [ABSTRACT FROM AUTHOR]
    • Abstract:
      Objetivou-se com este experimento avaliar a susceptibilidade de diferentes tubos gotejadores convencionais ao entupimento por ferro solúvel na água de irrigação (sulfato de ferroso) via duas qualidades de água (com e sem carga orgânica), sólidos suspensos (solo) e solução concentrada, com os emissores dos tubos gotejadores posicionados para baixo. O experimento foi realizado durante o período de 12 meses, com 7 modelos de tubos gotejadores. Os testes foram realizados em uma bancada de ensaios em estrutura metálica localizada no Laboratório de Irrigação, da Escola Superior de Agricultura "Luiz de Queiroz" - ESALQ/USP. A aplicação de partículas de solo e elevado teor de ferro, sem passar por filtragem intensificaram o processo de entupimento. Os modelos B, F e G apresentaram entupimento total a partir das 1296, 792 e 1152 horas de funcionamento. [ABSTRACT FROM AUTHOR]
