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. Also known as deep flow technique (DFT), floating raft technology (FRT), or raceway, this method uses a rectangular tank less than ...
Due to the disease-free environment unique to aeroponics, many plants can be grown at higher densities (plants per square meter) compared to more traditional cultivation methods like hydroponics, soil, and Nutrient Film Technique (NFT). Commercial aeroponic systems incorporate hardware features that accommodate the expanding root systems of crops.
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.
Plants placed into nutrient-rich water channels in an NFT system. A home-built NFT hydroponic system. Nutrient film technique ( NFT) is a hydroponic technique where in a very shallow stream of water containing all the dissolved nutrients required for plant growth is re-circulated past the bare roots of plants in a watertight gully, also known ...
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 ...
Whispering Roots is a non-profit organization in Omaha, Nebraska that provides fresh, locally grown, healthy food for socially and economically disadvantaged communities by using aquaponics, hydroponics and urban farming. [60] [61] Recently, aquaponics has been moving towards indoor production systems.
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 ...
Sod is typically harvested in small square or rectangular slabs, or large 4-foot-wide (1.2 m) rolls. The Mississippi State University has developed a hydroponic method of cultivating sod. For the very few sod farms that export turf internationally, this soilless sod may travel both lighter and better than traditional sod.
