Description: Hydroponic, or growing plants without soil, is a sustainable way to produce more in a given area. Increase in yield, fertilizer and water use efficiency are indubitable advantages of this system. However, closed hydroponic system, where a solution recirculates infinitely, are plagued with plant nutrition challenges. Most greenhouse producers do not use these types of systems as they have practical issues associated with them. These challenges are usually having the adequate nutrient concentration and ratio at a given time. However, Ion Selective Electrodes (ISE) are tools that can give a relatively precise measurement of a specific ion activity in a solution in an instant. Using this technology, next generation of hydroponic systems will be able to reuse solution that is qualified as waste. Furthermore, developing these automated nutrient analyzers will provide a cheaper research alternative to quantify nutrient uptake (or release) in plant. Ultimately, this technology will permit optimization of plant nutrition by using timing of fertilization as a variable. For example, pinpointing key developmental stages where nutrient demand is high could not only diminish fertilizer use at other time, but could also increase productivity of systems using this timely fertilization. Preliminary results on a model organism, basil, will be discussed. The limitations of said system and its implication in other field (wastewater management, space travel) is also a subject of interest. Increase in efficiency of systems by use of nutrient-rich organic biomass (chicken manure) is shown.
