Hydroponics Hydroponics Document Transcript

  • HydroponicsHydroponics is soil-less growing which means that we do not use any soil. In soil there arecontaminating bacteria and soluble pollutants and soil is not a solvent.What we do is we grow in inert mediums using nutrients which are just meals dissolved in wateras a food supply.Plants that are grown using hydroponics depend on the season.Ex of cool season’s plants: broccoli, cauliflower, cabbage, lettuce, carrotsEx of warm season’s plants: tomatoes, cucumbers, green beans, melons
  • Instead of soil, plants grow using water & fertilizers. We also use containers, tubes, sponges,and lights. We receive a small amount of light in the greenhouse but we need to provide it more.So we provide good artificial lights which is a mix of cool white fluorescent bulbs and plantgrow lights. This blend provides the right amount of red and blue light waves that the plant willuse to grow.ADVANTAGES OF HYDROPONICS1. Plants can be grown anywhere2. Better control over plant growth3. Less work with hydroponics4. Water and nutrients are conserved5. Pest and disease problems are reduced6. Transplanting shocks are reduced for seedlings7. Soil erosion problem is inexistence8. Culture is extensive
  • DISADVANTAGES OF HYDROPONICS1. Starting cost is high2. Sound technological know how is required for proper trainingADVANTAGES OF HYDROPONICS OVER SOIL In open air farming,it is difficult for farmers to regulate the level of nutrients to the plants. Plants that are grown using hydroponic system are able to get the right amount of nutrient required,since the plant are grown in a controlled environment. There is less work compared to an open air farming. Tilling of soil, watering the plants, fumigation, weed pulling or even animal problems are non-existent.
  • Plants grow faster when using hydroponics than in soil because the nutrients are dissolved in the waterand closely monitored, the plants will have access to the optimum conditions required for them to growwell.(in hydroponics)Hydroponics farms are also usually covered in a fine net which prevents attack by insects. The absenceof pests also mean the plants grow much better whereas in the open air farm the plants are attacked bypests which result in poor growth of plants.FUTURE USE OF HYDROPONICSFurther development of the application of solar heating in hydroponic greenhouses will reduce cost and economic impact ofhydroponics. Currently, plans are being drawn for using the techniques of soil-less culture on space stations, and perhapsone day on surfaces of other celestial bodies (planets, moons, etc.) that don’t have soil. In the future, developing countries,along with all other nations, will be able to feed many people using less land than current farming techniques. Advances inlighting technology will lead to a more widespread use of hydroponics in areas with limited seasonal sunlight. In the future,the application of hydroponics in providing food in areas having vast regions of non-arable land, such as deserts andmountainous terrain, will be more heavily used.
