Hydroponics vs. Aeroponics

Post  HBKings10 on Tue May 18, 2010 9:31 pm

Aeroponics is a system where roots are continuously or discontinuously kept in an environment saturated with fine drops (a mist or 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.
Aeroponic techniques have proved to be commercially successful for propagation, seed germination, seed potato production, tomato production, leaf crops and micro-greens.[7] 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 if aerators are utilized or not.
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 due to the fact that suspended aeroponic plants receive 100% of the available oxygen and CO2 to the roots zone, stems and leaves,[9] thus accelerating biomass growth and reducing rooting times. NASA research has shown that aeroponically grown plants have an 80% increase in dry weight biomass (essential minerals) compared to hydroponically grown plants. Aeroponics used 65% less water than hydroponics. NASA also concluded that aeroponically grown plants requires ΒΌ the nutrient input compared to hydroponics. Unlike hydroponically grown plants, aeroponically plants will not suffer transplant shock when transplanted to soil. Unlike hydroponics, aeroponics also offers growers the ability to reduce the spread of disease and pathogens.[10] Aeroponics is also widely used in laboratory studies of plant physiology and plant pathology. Aeroponic techniques have been given special attention from NASA since a mist is easier to handle than a liquid in a zero gravity environment.
Some of the reasons why hydroponics is being adapted around the world for food production are the following:
No soil is needed
The water stays in the system and can be reused- thus, lower water costs
It is possible to control the nutrition levels in their entirety- thus, lower nutrition costs
No nutrition pollution is released into the environment because of the controlled system
Stable and high yields
Pests and diseases are easier to get rid of than in soil because of the container's mobility
Today, hydroponics is an established branch of agronomy. Progress has been rapid, and results obtained in various countries have proved it to be thoroughly practical and to have very definite advantages over conventional methods of horticulture. The two chief merits of the soil-less cultivation of plants are, first, much higher crop yields, and second, hydroponics can be used in places where in-ground agriculture or gardening is not possible.
Thus not only is it a profitable undertaking, but one which has proved of great benefit to humanity. People living in crowded city streets, without gardens, can grow fresh vegetables and fruits in window-boxes or on rooftops. By means of hydroponics all such places can be made to yield a regular and abundant supply of fresh greens. Deserts, rocky and stony land in mountainous districts or barren and sterile areas can be made productive at relatively low cost[citation needed].
Other advantages include faster growth combined with relative freedom from soil disease, and consistency in crops, the quality of produce being excellent[citation needed]. There is also a considerable reduction in growing area. Weeds are practically non-existent, while standard methods and automatic operations mean less labor, lower cost, and less difficult manual labor. As some plants can be raised out of season, better control of crops naturally results
