Aeroponics is a technique of growing plants without the help of soil. The plants are suspended in mid air and they are supplied with nutrients by using a spray that ha water in it. When the roots absorb oxygen they also absorb all the essential nutrients through the spray.
Scientists have observed that the plant growth in the system of aeroponics is ten times higher than the soil method. Soil only plays a role of storage house of nutrients for the plant and the roots absorb them. If the nutrients can be provided to the roots through some other means, then we do not need the soil. A system like aeroponics is useful because plants can be grown in arid landscapes like the desert.
The system of aeroponics was first developed by scientists in 1920. Botanists actually observed that the absence of soil promoted plant growth in many ways. Also, it was much simpler to observe the plant growth in this system. However, in 1920 it was just an academic study. In 1970, hydroponics was also developed and both the systems were first put into use. Hydroponics is actually an offshoot of aeroponics. However, aeroponics made a big debut in 1982 when an entire set up was made in Disney Epcot Center. Also, NASA took special interest in it because it has several uses for this system. The concept behind aeroponics is very simple and people can even try it at home. Today, several researches are funded for the development of aeroponics.
