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]
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, [53] 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 ...
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 some cases net pots are not needed. For oxygenation of the hydroponic solution, an airstone is added.
Rice paddies in Balagtas, Bulacan. Agriculture in the Philippines is a major sector of the economy, ranking third among the sectors in 2022 behind only Services and Industry. Its outputs include staples like rice and corn, but also export crops such as coffee, cavendish banana, pineapple and pineapple products, coconut, sugar, and mango. [1]
Controlled-environment agriculture. 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.
Detail of an ebb-and-flow system, nutrient-rich water is pumped through the hoses connecting the containers. Ebb and flow hydroponics is a form of hydroponics that is known for its simplicity, reliability of operation and low initial investment cost. Pots are filled with an inert medium which does not function like soil or contribute nutrition ...
Underground farming. Underground farming is the practice of cultivating food underground. Underground farming is usually done using hydroponics, aeroponics or air-dynaponics systems or container gardens. Light is generally provided by means of growth lamps [1] or daylighting systems (as light tubes). [2]
