This study aimed to evaluate the nutrient utilization efficiency in strawberry hydroponics and assess the actual nutrient discharge status under a non-circulating hydroponic system. Water samples from both supply and drainage were collected three times monthly, at approximately 10-day intervals, from October to May of the following year, across five farms in Gyeongnam. A total of 18 parameters, including total N (T-N), total P (T-P), electrical conductivity (EC), and pH, were analyzed. The average drainage rate observed during the study period was 49.5%. The utilization efficiencies of macronutrients by the plants were 47.5% for T-N, 51.4% for T-P, 56.3% for K, 36.9% for Ca, 40.2% for Mg, and 33.5% for SO₄<sup>2-</sup>. Micronutrients such as Fe, Mn, B, and Mo demonstrated utilization efficiencies exceeding 50%, excluding Cu and Zn. During the survey period, the average total discharge amounts of using October data (the highest T-N and T-P discharges), these total discharges were calculated to 2.12 kg (T-N) and 0.67 kg (T-P) of average daily emissions per hectare, which shows the nutrient loads to be managed to mitigate the environmental pollution. This study established the foundation for reducing environmental pollution from non-circulating hydroponic systems by providing fundamental data on supply, drainage, and nutrient utilization efficiency. It highlights the need for further research into the reduction and reuse of drainage.
