The NITRISENS project aims to develop a method for manufacturing of a portable system for nitrite monitoring in soil based on an innovative electrochemical sensor inserted in a 3D printed soil solution extractor.
The integrated platform for onfield measuring of nitrite directly in soil which will be developed through NITRISENS project responds to the urgent need of a tool for soil nitrification monitoring and controlling in realtime. Market impact/benefits: realtime monitoring of soil pollution; reducing of amount of Nfertilizers; introducing on the market of costeffective tools for precision agriculture strategies; widening the range of products of the SMEs involved in project.
Specific objectives of the project are:
INNOVATION REGARDING CURRENT STATEOFTHEART
Nowadays, there are numerous analytical assays proposed for nitrite quantification which encompass sophisticated and centralized techniques such as ion chromatography, polarography, capillary electrophoresis, gas chromatography coupled to mass spectrometry (GCMS) or fluorescence spectroscopy. However, most of these analytical methods have shown important limitations such as sample pretreatment, susceptibility to matrix interferences, insufficient detection limits, long time of analysis and, more important, lack of portability and of ability to insitu nitrite determination.
