Zusammenfassung:The growth of microorganisms in the nutrient solution of a circulating hydroponic system was suppressed by ultra-violet radiation. Applied for three hours daily (572Jm⁻² h⁻¹) throughout experiments in which tomato and corn were grown, it was effective in reducing the population of microorganisms from between 500-800· 10³ to 10-50·10³ cells per ml.
