Kratky method. 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 ...
CEA technologies include hydroponics, aeroponics, aquaculture, and aquaponics. [2] Different techniques are available for growing food in controlled environment agriculture. Currently, the greenhouse industry is the largest component of the CEA industry but another quickly growing segment is the vertical farming industry. Controlled Environment ...
Vertical farming is the practice of growing crops in vertically and horizontally stacked layers. [ 1] It often incorporates controlled-environment agriculture, which aims to optimize plant growth, and soilless farming techniques such as hydroponics, aquaponics, and aeroponics. [ 1] Some common choices of structures to house vertical farming ...
Passive sub-irrigation, also known as passive hydroponics, semi-hydroponics, or hydroculture, [52] is a method wherein plants are grown in an inert porous medium that moves water and fertilizer to the roots by capillary action from a separate reservoir as necessary, reducing labor and providing a constant supply of water to the roots. In the ...
Organic hydroponics. Organic hydroponics is a hydroponics culture system based on organic agriculture concepts that does not use synthetic inputs such as fertilizers or pesticides. In organic hydroponics, nutrient solutions are derived from plant and animal material or naturally mined substances. [1] Most studies on the topic have focused on ...
Hoagland solution. The Hoagland solution is a hydroponic nutrient solution that was newly developed by Hoagland and Snyder in 1933, [ 1] modified by Hoagland and Arnon in 1938, [ 2] and revised by Arnon in 1950. [ 3] It is one of the most popular standard artificial solution compositions for growing plants, in the scientific world at least ...
