[Korean Farmers' News Agency reporter Kang Jae-nam] The Jeju Special Self-Governing Province Agricultural Technology Institute (Director Ko Sang-hwan) announced that it has completed the establishment of a digital-based hydroponic seed potato production system. Last year, the institute constructed an advanced greenhouse, and this year, it built a complex automatic control system that integrates the management of cultivation environments such as nutrient solution, temperature, ventilation, and shading to complete the digital-based production system. In the process of promoting the project, the institute analyzed accumulated weather data and nutrient solution supply data using machine learning methods to derive key reference values for nutrient solution supply control and established the basic framework for a nutrient solution supply model based on fuzzy control to respond to changes in external environments such as temperature, solar radiation, and humidity.
