Water Treatment for Closed Hydroponic Systems

Growth and Quality of the Strawberry (Fragaria annanassa Dutch. cvs. ‘Sulhyang’) as affected by Complex Nutrient Solution Supplying Control System using Integrated Solar Irradiance and Substrate Moisture Contents in Hydroponics

“…수경재배는 토양이 아닌 배지에서 양액을 이용하여 작물에 양분을 공급하는 방법으로, 수경재배를 통해 집약적이고 효 과적인 작물 관리가 이루어질 수 있다 (Dorais 등, 2001). 배액 을 재활용하는 순환식 수경재배 비율은 우리나라 5% 미만인 실정이며 대부분 비순환식 수경재배로 양액을 공급하고 있다 (Lee와 Kim, 2019). 수경재배에서 급액 제어는 작물의 생장 을 최적의 상태로 유지하고 배양액의 손실을 최소화하며 품질 을 높이기 위해 행해지며 급액량, 배액량, 배지 내 함수량 등을 고려해야한다.…”

Contamination and Spatial Distribution of Metal(loid)s in the Stream Sediment near the Greenhouse

“…There are cases of wastewater discharged from greenhouse crop cultivation and nutrients accumulated in the soil, contaminating groundwater, streams, rivers, and agricultural fields [34][35][36][37]. For this reason, countries such as the Netherlands, Spain, and Japan are developing recycling methods that do not discharge wastewater [38][39][40][41][42]. Nutrients such as N, P, K, and Mg are the main fertilizer components of wastewater discharged from facility horticulture [43][44][45][46].…”

Theoretical and Experimental Analyses of Nutrient Control in Electrical Conductivity-Based Nutrient Recycling Soilless Culture System

“…However, in practice, the application of CL soilless culture systems is scarce. In South Korea, the proportion of soilless culture occupied by the CL system is only 5% ( Lee and Kim, 2019 ). In Almería, the highest area of soilless production in Spain, only 12% of 3,000 ha soilless cultivation are as uses the drainage reuse system ( Massa et al, 2020 ).…”
