본 조사는 전라북도 양액재배 25개 농가의 원수를 채취하여 무기이온을 중심으로 한 수질상태를 분석하여 배양액 조성에 필요한 기초자료를 얻기 위하여 수행하였다. 양액재배에 이용되는 원수의 수질 분석 결과에서 pH의 수준은 6.00-7.65로서 평균 6.58이었다. 전기전도도(EC)의 분포범위는 0.01-0.94 mS/cm로서 평균 0.23 mS/cm이었다. Na과 Cl의 분포범위는 각각 4.71-145.44 ppm, 0-171.80 ppm로서 평균 24.24 ppm, 26.33 ppm이었다. 7.7%의 농가가 Na과 Cl의 함량이 다른 농가와 비교할 때 대단히 높게 조사되어 이들 농가의 원수 수질은 부적합하였다. K, Ca 및 Mg의 분포범위는 각각 0.93-17.38 ppm, 2.29 3.30 ppm 및 0.70 18,61 ppm로서 평균 3.06 ppm, 13,00 ppm 및 4.91 ppm이었다. SO4와 PO4의 함량 범위는 각각 0.63-59.79 ppm과 0-4.28 ppm로서 평균 18.11 ppm과 0.51 ppm이었다. Cu와 Zn의 함량 범위는 0-0.32 ppm과 0-6.22 ppm로서 평균 0.02 ppm과 0.52 ppm이었다.

This analysis has been conducted to get some basic data of the composition of culture solution mostly in inorganic ions, and water quality in hydroponic farms in Chollabuk - do. pH range was shown from 6.00 to 7.65 and the average was 6.58. EC range was shown from 0.01 to 0.94 mS/cm and the average was 0.28 mS/cm. Na concentration ranged from 4.71 to 145.44 ppm and Cl concentration ranged from 0 to 171.80 ppm were shown and their average were 24.24 ppm and 26.33 ppm, respectively. Na and Cl concentrations were higher as 7.7%, compared to those of other farms, which could cause the salt accumulation in the substrate mats. K, Ca and Mg concentrations were ranged from 0.93 to 17.38 ppm, 2.29 to 34.30 ppm and 0.70 to 18.61 ppm, respectively. Average concentrations were 3.06 ppm in K, 13.00 ppm in Ca and 4.91 ppm in Mg. 50, and PO4 concentration ranged from 0.63 to 59.79 ppm and 0 to 4.28 ppm were shown and their average were 18.11 and 0.51 ppm. Cu concentration was ranged from 0 to 0.32 ppm and 0 to 6.22 ppm in Zn concentration. Their average were 0.02 ppm and 0.52ppm, respectively.
