Estudo sobre os principais aspectos da produção de alface hidropônica

Abstract

Due to changes in eating habits the lettuce consumption is increasing, and its daily supply, year-round, so the hydroponic cultivation has been adopted by many producers. Hydroponics is an agricultural technique, in which plants are grown without soil, and as a source of development are necessary nutrients for their growth. The Hydroponics word of Greek origin, is formed by the composition of HYDOR words meaning water, ePONOS (ancient Greek), meaning work, to work executada.A Hydroponics can use the soil as long as it is free of materials capable of biodecomposição, and mineral salts, organo-mineral or organic, capable of ionisation and dissolution in water. Hydroponics is practiced normally on the sands of deserts. The History of Hydroponics, dating back to ancient civilizations, from Egyptian and Chinese, passes through the Aztec civilization in Central America, and reaches our days, when it is determined that your application is the only way to produce fresh food for future astronauts, in space travel, and stay at stations in space. In this study, a literature search focusing on the main aspects of lettuce production for hydroponics as a good alternative source of income for small farmers and list the main advantages of the technique in relation to sustainable development and production of healthy and safe food was made for consumers. And also seeking solutions to minimize environmental impacts such as pollution and soil pollution is water.
