Abstract

A model is proposed for the simulation of nutrient solution flow in a Nutrient Film Technique (NFT) system, and uptake by plants.
The system is consisted of a channel with a thin layer of a porous material.
The nutrient solution would be applied via dripping emitters, uniformly spaced along the channel, and drain to a reservoir.
The solution would then be compensated for water and nutrients losses, and re-pumped to the irrigation system.
The model was tested against N and K uptake by growing lettuce (Lactuca sativa L.) plants.
Uptake of the major nutrients and the effects of salinity buildup were simulated and discussed.
