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 Kratky method is a passive hydroponic technique for growing plants suspended above a reservoir of nutrient-rich water. [1] Because it is a non-circulating technique, no additional inputs of water or nutrients are needed after the original application, and no electricity, pumps, or water and oxygen circulation systems are required. [2]
Saltwater aquaponics (also known as marine aquaponics) is a combination of plant cultivation and fish rearing (also called aquaculture), systems with similarities to standard aquaponics, except that it uses saltwater instead of the more commonly used freshwater. In some instances, this may be diluted saltwater.
Deep water culture has also been used by hobby growers. Net pots, plastic pots with netting to allow roots to grow through their surface, are filled with a hydroponic medium such as Hydroton or [Rockwool] to hold the base of the plant.
In an aquaponics system fish effectively fertilize the plants, this creates a closed looped system where very little waste is generated and inputs are minimized. Aquaponics provides the advantage of being able to harvest and sell multiple crops. Contradictory views exist on the suitability and safety of RAS effluents to sustain plant growth ...
The deep water raft tank at the Crop Diversification Centre (CDC) South Aquaponics greenhouse in Brooks, Alberta. In static solution culture, plants are grown in containers of nutrient solution, such as glass Mason jars (typically, in-home applications), pots, buckets, tubs, or tanks. The solution is usually gently aerated but may be un-aerated ...
Subirrigation also known as seepage irrigation, is a method of irrigation where water is delivered to the plant root zone. The excess may be collected for reuse. ...
