    Control of hydroponic nitrate nutrition (Technical Article)

    A strict control of nitrate concentration in hydroponics during long-term experiments requires real-time analyses that cannot be performed manually. Adamowicz et al. describe a novel automatic set-up that measures and regulates nitrate concentration, pH and solution volume, allowing the calculation of nitrate uptake rates. The system is shown to be reliable at high temporal resolution (minutes […] More
