An aquaponics system combines hydroponics with aquaculture in a recirculating system, mimicking many of nature’s natural cycles.
Aquaponic farming avoids chemical fertilizers by using fish to provide nutrients for the plants. The plants grow in a soil-free environment and clean the water for the fish. The fish and plants work together so the water can be recycled indefinitely. You only need to replace water that has evaporated drastically reducing water consumption.
Aquaponics is becoming popular among people concerned about nutrition avoiding artificial additives and making a contribution to protect the environment. You can create an aquaponics garden almost anywhere. You do this by bringing together light and space using a footprint as small as a single square meter. Once the system is cycling, the need to water or weed is neutralized. More plants can grow in much less space, compared to traditional farming and the plants will grow faster and more robust.
“You feed the fish, the fish feed the plants and the plants clean the water for the fish.”
Fish secrete ammonia mainly through their gills. One genus of bacteria (Nitrosomonas) converts ammonia to nitrite while another genus of bacteria (Nitrobacter) converts nitrite to nitrate. Oxygen is required for these chemical transformations, a process known as nitrification. Plants thrive in the high levels of nitrates with this farming method making it one of the most sustainable forms of farming currently known to man.
