The nutrient film technique (nft) in aquaponics is a method in which the plants are grown in a long narrow channel. nft is a hydroponic growing technique that is adapted to aquaponics because of its simple yet effective design and works well in some environments.. The nutrient film technique is a type of aquaponics system that cultivates plants in long canals. periodically, films of water flow through each canal, delivering oxygen and nutrients to the vegetable roots.. In nutrient film technique, the oxygen concentration can deplete heavily during the daytime. besides the root respiration also microorganisms, living in the root zone of the plants, consume oxygen and have to be con-sidered. in double recirculating aquaponic systems (draps) fish waste water is used for preparation of nutrient.
Menurut apriyanti dan desi (2016) sistem nutrient film te c hnique (nft) merupakan kebalikan dari sistem deep flow technique (dft). dimana, pada sistem nft mengalirkan nutrisi yang sangat tipis. Nutrient film technique, or nft, is a popular and versatile hydroponics system. it is similar to ebb and flow in that the system uses a pump to deliver fertilized water to the grow tray and a drain pipe to recycle the unused nutrient solution. the difference is that in nft the nutrient solution is continuously flowing over the roots.. Many hydroponic techniques exist 1.nutrient film technique 2.deep water hydroponics 3.flood & drain/floating system sub‐irrigation 4.aeroponics 5.aquaponics nutrient film technique(nft) is a hydroponic techniquewherein a very shallow stream of water containing all the dissolved nutrientsrequired for.
