“…Park et al (2005) reported that combined treatment with chemical fertilizer (70%) and waste nutrient solution (30%) promoted the crop (2006) reported that musk melon plants cultivated by fertigation (fertilization + irrigation) using waste nutrient solution increased plant height and root length compared to those grown in hydroponic systems. The growth of Chinese cabbage seedlings irrigated with waste nutrient solution was similar or greater than that of plants irrigated with groundwater (Hong et al, 2009). Additionally, the N uptake of Chinese cabbage seedlings irrigated with waste nutrient solution at a dose 50% lower than a recommended dose was higher than that of plants irrigated with groundwater.…”

BACKGROUND:Reuse of waste nutrient solution for the cultivation of crops could lead to considerable conservation of water resources, plant nutrients, and water quality. Therefore, this study was conducted to evaluate the potential for reducing the use of chemical fertilizer in Chinese cabbage cultivation via the reuse of waste nutrient solution as an alternative irrigation resource. METHODS AND RESULTS:The nutrients supplied in the waste nutrient solution consisted of 1474.5, 1285.1, 991.6, and 872.6 mg/L for K

“…The main purpose of this study was to determine the amount of fertilizer that is discarded and propose its management as a pollutant. However, since the HWW discharged from hydroponics contains water, it is considered necessary to study the reuse of HWW to conserve water resources at a time when global water shortage is emerging [56,[139][140][141][142][143][144][145].…”

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.

Hydroponic waste solution (HWS) used in greenhouse facilities for horticultural crop production gets discharged into water bodies contributing environmental pollution associated with agriculture. In this study, we evaluated possibility of reusing HWS from paprika cultivation production as fertilizer for paddy rice production. Different concentrations of the HWS were obtained through dilution with irrigation water. Four treatments of C (conventional), T 1 (×10 diluted HWS as a fertigation), T 2 (×20 diluted HWS as a fertigation), T 3 (HWS as a fertilizer at the level of 100% of the standard nitrogen fertilization rate) were used in the study. The preliminary results on the growth of the rice showed significant effect of the different HWS concentrations on the height and number of tillers growth of the rice. Height growth and number of tillers followed similar trends in the order of C > T 1 = T 3 > T 2 . At 3 weeks after planting, a significantly high coefficient of correlation (R 2 ) of 0.984 and 0.968 were observed except for T 3 between total nitrogen (N) and plant height; and N and number of tillers respectively. Thus, suggesting total nitrogen contribution from each treatment is a major factor in the growth of the rice. The results at the initial growth stage of the rice suggest, adjusting N concentration in HWS and appropriate timing of HWS application could enable the reuse of HWS in paddy rice production.
