Fuzzy Logic Controller for Automating Electrical Conductivity and pH in Hydroponic Cultivation
This study proposes a fuzzy logic controller for adjusting the electrical conductivity (EC) and pH of the nutrient solution in a hydroponic system. The proposed control system detects the EC and pH of the solution through sensors and adjusts the working ...

Abiotic and biotic factors in the nutrient solution and filter skin (Schmutzdecke) of slow filters integrated to closed hydroponic greenhouse systems [PDF]
Rapid pathogen dispersal by circulating nutrient solutions in closed hydroponic systems poses a major threat to this production method. Slow filtration is very effective against important fungal pathogens such as Phytophthora cryptogea and Pythium ...

DEVELOPMENT OF AUTOMATED PH CONTROLLER SYSTEM FOR NFT HYDROPONIC
In a hydroponics system, pH level is one of the most important parameters that affect the way plants respond to a hydroponic nutrient solution. The range of pH levels depends on the type of plants in the hydroponic system.

CHELATION OF TRACE METALS IN NUTRIENT SOLUTIONS [PDF]
The effect of chelating agents added to nutrient solutions on plants growing in these solutions was investigated. Chelating chemicals used were: 8-hydroxyquinoline (oxine), sodium diethyldithiocarbamate (carbamate), sodium 1:8 dihydroxynaphthalene 3:6 disulphonate (chromatropic salt), sodium 1-nitroso-2-naphthol 3:6 disulphonate (nitroso-R-salt ...
