    Categories. Agriculture portal. v. t. e. Hydroponics[1] is a type of horticulture and a subset of hydroculture which involves growing plants, usually crops or medicinal plants, without soil, by using water-based mineral nutrient solutions in an artificial environment.

  3. Vertical farming - Wikipedia

    en.wikipedia.org/wiki/Vertical_farming

    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 ...

  4. Aquaponics - Wikipedia

    en.wikipedia.org/wiki/Aquaponics

    Agriculture. 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. [1]

  5. Controlled-environment agriculture - Wikipedia

    en.wikipedia.org/wiki/Controlled-environment...

    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.

  6. Deep water culture - Wikipedia

    en.wikipedia.org/wiki/Deep_water_culture

    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. Also known as deep flow technique (DFT), floating raft technology (FRT), or raceway, this method uses a rectangular tank less than one foot deep filled with a nutrient-rich solution with ...

  7. Kratky method - Wikipedia

    en.wikipedia.org/wiki/Kratky_method

    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 ...

  8. Organic farming - Wikipedia

    en.wikipedia.org/wiki/Organic_farming

    t. e. Organic farming, also known as ecological farming or biological farming, [1][2][3][4][5] is an agricultural system that uses fertilizers of organic origin such as compost manure, green manure, and bone meal and places emphasis on techniques such as crop rotation and companion planting. It originated early in the 20th century in reaction ...

  9. Greenhouse - Wikipedia
