Vertical farming

Vertical farming is the practice of producing food and medicine in vertically stacked layers, vertically inclined surfaces and / or integrated in other structures (such as in a skyscraper, used warehouse, or shipping container). The modern ideas of vertical farming techniques and controlled-environment farming (CEA) technology, where all environmental factors can be controlled. These facilities use artificial control of light, environmental control (humidity, temperature, gases …) and fertigation . Some of the most common uses of greenhouses , where natural sunlight can be augmented with artificial lighting and metal reflectors. [1] [2] [3] Continue reading “Vertical farming”

Recirculating aquaculture system

Recirculating aquaculture systems ( RAS ) are used in home aquaria and for fish products Where water exchange is limited and the use of bio-filtration is required to Reduce ammonia toxicity. [1] Other types of filtration and environmental control are also required to maintain a suitable habitat for fish. [2]The main benefit of RAS is the ability to reduce the need for fresh water. To be exploited economically commercial RAS must have high fish stocking densities, and many researchers are currently conducting studies to determine if it is a viable form of intensive aquaculture . [3] Continue reading “Recirculating aquaculture system”

Aquaponics

Aquaponics ( / æ k w ə p ɒ n ɪ k s / ) Refers to-any system That combined conventional aquaculture (raising aquatic animals Such as snails, fish , crayfish or prawns in tanks) with hydroponics (Cultivating plants in water) in a symbiotic environment. In normal aquaculture, excretions from the animals being raised in the water, increasing toxicity. In an aquaponic system, water from an aquifer system is fed to a hydroponic system where the by-products are broken down by nitrifying bacteria initially into nitrite and further into nitrates , which are used by the plants as nutrients , and the water is then recirculated. back to the aquaculture system.

As existing hydroponic and aquaculture farming techniques, the size, complexity, and types of foods in an aquaponics system can vary widely. [1] Continue reading “Aquaponics”
