Abstract
The present invention relates to a nutrient solution recycling plant cultivation system, which recycles and supplies a cultivation nutrient solution and measures in real time the composition of each nutrient component to be added to a waste nutrient solution through a so-called soft sensor using measured values of pH, EC, temperature, turbidity, and weight and a previously constructed estimation model instead of an expensive high-performance analyzer, thereby minimizing nutrient solution consumption while meeting a required level of accuracy.
