1. Aeroponics is a system wherein roots are continuously or discontinuously kept in an environment saturated with aerosol of nutrient solution. The method requires no substrate and entails growing plants with their roots suspended in a deep air or growth chamber with the roots periodically wetted with a fine mist of atomized nutrients. Excellent aeration is the main advantage of aeroponics.
2. Aeroponic techniques have proved to be commercially successful for propagation, seed germination, seed potato production, tomato and leaf crops production. Since inventor Richard Stoner commercialized aeroponic technology in 1983, aeroponics has been implemented as an alternative to water intensive hydroponic systems worldwide. The limitation of hydroponics is the fact that 1 kg of water can only hold 8 mg of air, no matter whether aerators are utilized or not.
3. Another distinct advantage of aeroponics over hydroponics is that any species of plants can be grown in a true aeroponic system because the micro environment of an aeroponic can be finely controlled. The limitation of hydroponics is that only certain species of plants can survive for so long in water before they become water-logged. The advantage of aeroponics is that suspended aeroponic plants receive 100% of the available oxygen and carbon dioxide to the roots zone, stems, and leaves, thus accelerating biomass growth and reducing rooting times. Unlike hydroponically grown plants, aeroponically grown plants also will not suffer transplant shock when transplanted to soil, and offers growers the ability to reduce the spread of disease and pathogens.
Определите основную идею текста.
Aeroponic techniques present a different way of plant growing enabling people to get better harvest while spending less money on this process.
Aeroponics is a more favourable technique due to the fact that aeroponic plants are fully aerated promoting biomass growth.
Aeroponics is a modern technique of plant growing when plants require no substrate while the roots are periodically wetted with a fine mist of atomized nutrients.
In comparison with hydroponics aeroponics is more effective and economically profitable way of plants growing involving their development from seed germination up to maturing.
