“…In developed European countries, such as the Netherlands, the percentage of hydroponics farms that reuse nutrient solutions is 95%, while in Japan, it is 15%. In contrast, South Korea has a much lower percentage, less than 5% [1,2,4,[19][20][21][22][23][24][25][26]. The Netherlands implemented a mandate in 2004 requiring all greenhouses to be converted to circular systems.…”

“…Greenhouses in Korea have been built up for environmental friendly facilities with a recycling and reprocessing system for the reuse of nutrients and drainage [1,2,4,24,25]. However, the majority of farmersapproximately 95%-in South Korea use non-circulating hydroponic systems with low facility costs [1,2,20,26]. This indicates an urgent requirement to establish agricultural recycling technologies to reduce the environmental pollution caused by the discharge of waste nutrients from non-circulating hydroponic systems [1,2,4,27].…”

Among the horticulture facilities in Korea, the hydroponic cultivation method has been increasingly used. This study aimed to identify fungi and bacterial species in hydroponic cultivation and highlight the need for sterilization to recycle the discharged drainage. Samples were collected from a number of paprika, tomato, and strawberry hydroponic greenhouses. Vinyl and glass greenhouses were studied, and the drainage discharge was of two types: direct discharge and collection after discharge. In total, 24 fungal and six bacterial species were detected from 399 and 151 densities, respectively. The primary fungal and bacterial species identified were from the genera Fusarium, Pythium, and Phytophthora as well as Agrobacterium and Pseudomonas. Statistical analysis revealed that the species number and density of fungi and bacteria were higher in strawberry than in tomato or paprika. These values were higher for vinyl greenhouses than for glass greenhouses. This study on the reuse of drainage from hydroponic greenhouses may contribute to the recycling of resources and reduction in water pollutant emission; this will thus help us to implement sustainable horticulture practices.
