iAVs schematic diagram Tomato transplants in a biofilter (composed of sand, bacteria and plants) shown being irrigated with aquacultural water for the first time.. The Integrated Aqua-Vegeculture System (iAVs), also informally known as Sandponics, [1] is a food production method that combines aquaculture and horticulture (olericulture). [2]
Aquaponics is a food production system that couples aquaculture (raising aquatic animals such as fish, crayfish, snails or prawns in tanks) with hydroponics (cultivating plants in water) whereby the nutrient-rich aquaculture water is fed to hydroponically grown plants.
The first step of nitrification in the biofilter consumes alkalinity and lowers the pH of the system. [10] Keeping the pH in a suitable range (5.0-9.0 for freshwater systems) is crucial to maintain the health of both the fish and biofilter. pH is typically controlled by the addition of alkalinity in the form of lime (CaCO 3 ) or sodium ...

Plants placed into nutrient-rich water channels in an NFT system A home-built NFT hydroponic system. Nutrient film technique (NFT) is a hydroponic technique where in a very shallow stream of water containing all the dissolved nutrients required for plant growth is re-circulated past the bare roots of plants in a watertight gully, also known as channels.
