The Key To The Future of Farming: "Aquaponics"

8 Year old Amita Gowda is probably doing what most of us should be doing, figuring out ways to better the environment. On a trip to Ouroboros and School Grown Farms she talks about her discovery of "aquaponics" a farming technique that might be an answer to helping us grow plants and fish at the same time.

Recently, I visited two aquaponics farms. The farms were called, “Ouroboros Farms” and “SchoolGrown.” The tour of these aquaponics farms was thrilling because I like plants and animals. Aquaponics is an alternate farming method that combines Aquaculture and Hydroponics. Alternate farming methods are going to play a very important role in our future. We can also grow plants without soil. 

Here are some fascinating details I learned.

Last year people ate more fish than beef. That is very important to note. We really need more supplies of vegetables and we also need more fish. But with the changing climate and droughts, it is a huge challenge. Aquaponics is the answer to this challenge. Aquaponics also conserves water. An aquaponics fish farm uses  99% less water, no cleaning is needed, and there is no need to change the water. Vegetables are grown with 90% to 95% less water, as the water is re-circulating. With this method we can grow more vegetables in less space and without soil. About 10 to 12 heads of lettuce can be grown per sq. ft., whereas in the old soil farming, only about 3 heads of lettuce per sq. ft. can survive because the roots need more space. The roots of one lettuce plant in the soil spread over large areas and can get as big as a Volkswagen beetle car! The plants grown in aquaponics farms grow fewer roots, just enough to absorb the nutrients from the water, and they put all their energy in the rest of the plant growth, so plants are actually healthier. The aquaponics farm grows 900 carrots in just 2 sq. ft.

In fish farms the nitrate level goes as high as 1300-1400 ppm, which is toxic. Dr. Rakocy made the filtration system that removes the toxics and keep the nutrients. 

The duckweed plants, algae, worms, and other small good living creatures create an ecosystem that can feed the fishes as well as create minerals for plants. Not only vegetables, but other types of crops like rice can also be grown with the aquaponics method.

The Ouroboros farm is organic. The pesticide used is Neem based. Mosquito fish are grown to eat insects. They strive hard to keep everything organic to maintain a good balanced ecosystem.  The aquaponics farm with solar technology is the non-profit organization, “SchoolGrown.” Their new solar powered water circulating system uses just 20W of energy to move 500 gal. of water. The solar roof is used for filtration and other energy needs.

Aquaponics farms conserve energy, conserve water, crops can be grown all year round, have less pests, are organic, and is soilless. The benefits are huge! I would like to end with John Cage’s quote, “I can’t understand why people are frightened of new ideas. I’m frightened of old ones!”
