“…In general, the crops are planted in September, ending a one-time cycle. In Korea, the maximum temperature rises to about 35 degrees from June to August, with a high humidity, making it difficult for crops to grow inside the greenhouse [5,[61][62][63]. In some areas, crops are produced in the summer, but temperature control is difficult [64].…”

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.

“…South Korea has four distinct seasons. Korean greenhouse horticulture was created to overcome the inability to produce crops in winter [11][12][13]. In addition, the hot weather in the summer makes it difficult to produce crops and the cost of cooling is high [132][133][134].…”

“…Among the improvements, the horticulture industry has been able to grow a variety of vegetables and fruits even in winter by keeping them warm using horticulture greenhouses [11][12][13]. The horticulture industry in Korea has been recognized as a "white revolution" because it generates a lot of income [12,13]. It accounts for more than 40% of the horticulture industry, ranking third in the world in terms of area and significantly contributing greenhouse horticulture to the total agricultural income [11,[14][15][16].…”

In South Korea, the use of hydroponic cultivation has been on the rise. However, this system produces a large amount of wastewater. In this study, the amount of wastewater generated by hydroponic tomato cultivation is identified, and a management plan is proposed. Based on the analysis of 103 tomato HWW samples, it was found that the electrical conductivity (EC) was 4.25 ± 1.01 dS/m, the nitrogen (N) content was 411.21 ± 122.64 mg/L, and the phosphorus (P) content was 47.74 mg/L, which caused eutrophication. Therefore, agricultural reuse and HWW treatment were proposed. Regarding the annual HWW load, 1 ha of hydroponics discharges 964.26 kg/ha of N, 111.95 of P, 937.46 of K, 795.14 of Ca, 313.83 of Mg, and 405.40 of S. The trace elements were heavy metals, which were calculated as Fe—4.03, Mn—0.77, Zn—1.08, B—2.25, Cu—0.38, and Mo—0.05 kg/ha. Since wastewater is a national source of drinking water, it needs to be collected and treated. Inter-item correlation analysis showed that most of the fertilizer components were correlated with the EC concentrations. This study can be used to determine the concentrations required for agricultural reuse and to determine the treatment capacity in HWW management.

As greenhouse horticulture continues to increase in South Korea, the effects of metal(loid)s from wastewater discharges on stream sediments were analyzed. A total of 106 samples were analyzed for cadmium (Cd), boron (B), copper (Cu), nickel (Ni), lead (Pb), zinc (Zn), chromium (Cr), manganese (Mn), and iron (Fe). The coefficient of variation (CV) of the metal(loid)s components was 96.58% for Mn, 93.40 for Zn, 62.47 for B, 58.90 for Pb, and 58.14 for Cd, suggesting anthropogenic sources. Correlation analysis suggested a cumulative source for Cd-Zn and B, and cluster analysis suggested an anthropogenic source for Cu, Pb, B, and Mn. The contamination factor (CF) suggested the need to trace the source of contamination to Pb (3.21 ± 1.89) and B (1.33 ± 0.83) and EF to Pb (3.30 ± 1.81) and B (1.44 ± 0.94). The analytical results identify anthropogenic sources of Pb, B, and Cd. The high contamination of Cd suggests the influence of mining areas, and Pb suggests the influence of traffic, fertilizers, pesticides, and fossil fuels in greenhouses, in addition to the influence of mines. B confirmed the impact of the facility’s vegetable wastewater and suggested the need to further examine the cumulative impact of Mn, Fe, etc. By utilizing the facility horticulture wastewater for ecological restoration and other agricultural uses, we aim to prevent stream sediment pollution and realize a sustainable agricultural environment.
