Research into hydroponic gardening and aquaculture began at NASA.  Fruits, vegetables, herbs and other plants were grown without the use of soil and sometimes without the use of water as well.  The purpose of NASA's involvement in hydroponic research was to find a way to grow food in space. 

On hydroponic farms, fruit, vegetable and herb plants are suspended in the air on a rotating fixture where they are sprayed intermittently with a nutrient solution which provides nourishment for the plants.  Check out the Living with the Land information on the Walt Disney World website to see how hydroponics works.

Sustainability in agricultural techniques is a serious concern for farmers of the future.  As soil continues to erode and lose nutrients, it is becoming increasingly difficult for traditional farms to survive. 


Along with hydroponics, the farms of the future are making strides in integrated pest management (reduction of pesticides), crop rotation, inter-cropping and other irrigation technology.  Check out what the University of Georgia's College of Agriculture and Environmental Science is doing with integrated pest management and other plant science research.

Hydroponics may be the key to producing an adequate food supply for a growing global population using less land. With hydroponics, massive crop rotation may be done without much soil disturbance.  The nutrient solutions may be recycled and purified so that hydroponics actually uses less water than traditional farming techniques. 


One of the best aspects of hydroponic farming is the fact that food can be grown in areas that are traditionally too cold, too dry or otherwise inhospitable for farming.  This means that with help, some third world countries with starving populations may learn to grow adequate food to feed their people.

Next time you visit Florida, stop by Disney World's EPCOT, and visit the hydroponic farm in the "Living with the Land" Pavilion.  This joint venture between Disney and NASA is fascinating and supplies much of the food consumed by tourists at EPCOT.


You can use this concept to grow your own fruits and veggies at home on a smaller scale with an aeroponic gardening system.
