Abstract

This survey has been conducted to obtain basic data of the quality of ground water for hydroponics and waste nutrient solution after hydroponics in hydroponic farms in Chungbuk area. Ground water samples were collected and analyzed at 19 sites of hydroponic farms. Waste nutrient solution samples were analyzed at 15 sites selected of them. The values of several components in ground water for hydroponics were as follows. pH range was shown from 6.2 to 7.7 and the average was 6.8. EC range was shown from 0.10 to 0.45 dS $m^{-1}$ and the average 0.23 dS $m^{-1}$. $NO_3-N$ concentrations was ranged from 0.12 to 13.77 mg $L^{-1}$, $SO_4^{2-}$ concentrations was ranged from 1.84 to 63.01 mg $L^{-1}$ and $Cl^-$ concentrations were ranged from 10.46 to 72.09 mg $L^{-1}$. Average values of $NO_3-N$, $SO_4^{2-}$ and $Cl^-$ were 4.00 mg $L^{-1}$, 12.70 mg $L^{-1}$ and 27.57 mg $L^{-1}$, respectively. $Ca^{2+}$, $Mg^{2+}$ and $Na^+$ concentrations were ranged from 3.24 to 36.99 mg $L^{-1}$, 1.44 to 14.93 mg $L^{-1}$ and 6.12 to 25.25 mg $L^{-1}$, respectively. Average concentrations were 13.06 mg $L^{-1}$ in $Ca^{2+}$, 6.02 mg $L^{-1}$ $Mg^{2+}$ and 12.08 mg $L^{-1}$ in $Na^+$. In waste nutrient solution after hydroponics, pH range was shown from 4.3 to 8.8 and the average was 6.7. EC range was shown from 0.44 to 2.37 dS $m^{-1}$ and the average 1.15 dS $m^{-1}$. Range of $NO_3-N$, $PO_4-P$, $K^+$, $Ca^{2+}$, $Mg^{2+}$ and $Na^+$ in waste nutrient solution were $10{\sim}212$, $0.56{\sim}26.1$, $10{\sim}295$, $16{\sim}215$, $9{\sim}54$ and $10{\sim}53$ mg $L^{-1}$ respectively. Average concentration were 100 mg $L^{-1}$ in $NO_3-N$, 12.15 mg $L^{-1}$ in $PO_4-P$, 99 mg $L^{-1}$ in $K^+$, 78 mg $L^{-1}$ in $Ca^{2+}$, 26 mg $L^{-1}$ in $Mg^{2+}$ and 26 mg $L^{-1}$ in $Na^+$. Inorganic matters in waste nutrient solution after hydroponics was higher than that of ground water for hydroponics.
