[Kim Young-min, Korea Farmers' News Reporter] #Case 1 The traditional method of harvesting water spinach was limited to three times a year, resulting in low profitability and supply instability. To overcome this, Kim Tae-gyeong, the representative of Dasom Farm located in Yangju, Gyeonggi Province, installed a smart farm and a two-layer bed, increasing the number of water spinach harvests to 10-12 times a year. Furthermore, instead of using a high-cost nutrient solution controller, he developed and installed a low-cost smart nutrient supply system based on a metering pump. Kim's challenge did not stop there. To improve the traditional soil cultivation method, which resulted in leftover nutrient solution being treated as wastewater, causing environmental burden and costs, he added the recycled solution to the soil cultivation.
