Therefore, "aquaponics" can be translated to "water work," though this may not fully describe the system's function and purpose. Clear definitions are important in discussions about eco-certification. Currently, aquaponics is not included in the European Union's organic agriculture certification scheme because it uses hydroponics. However ...
This is a history of notable hydroculture phenomena. Ancient hydroculture proposed sites and modern revolutionary works are mentioned. Included in this history are all forms of aquatic and semi-aquatic based horticulture that focus on flora: aquatic gardening, semi-aquatic crop farming, hydroponics, aquaponics, passive hydroponics, and modern aeroponics.
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 ...
Fish was an important food source in medieval Europe, when in average 150 days per year were days of fasting and abstinence, and meat was prohibited. [184] Improvements in transportation during the 19th century made fresh fish easily available and inexpensive, even in inland areas, rendering aquaculture less popular.
The various hydroponic media available, such as expanded clay and coconut husk, contain more air space than more traditional potting mixes, delivering increased oxygen to the roots, which is important in epiphytic plants such as orchids and bromeliads, whose roots are exposed to the air in nature. Additional advantages of passive hydroponics ...
Controlled-environment agriculture (CEA) -- which includes indoor agriculture (IA) and vertical farming—is a technology-based approach toward food production. The aim of CEA is to provide protection from the outdoor elements and maintain optimal growing conditions throughout the development of the crop.
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.
An example of deep water culture in lettuce production. Deep water culture (DWC) is a hydroponic method of plant production by means of suspending the plant roots in a solution of nutrient-rich, oxygenated water.
