Collaborative project: Development of a low-priced miniaturized mid-infrared (MIR)-sensor for integrated area wide slurry management, Subproject 4

Project

Project code: 2815700415
Contract period: 01.04.2016 - 31.05.2019
Budget: 234,128 Euro
Purpose of research: Experimental development

"The project ""Development of a cost-effective and miniaturized mid-infrared (MIR) sensor system for integrated, area-wide slurry management"" (BigSIGMA), aimed to develop measurement technology, software and chemometric models enabling the online determination of the main components of slurry (dry matter, total nitrogen, ammonium nitrogen and phosphorus (P2O5)). The project showed that the mid-infrared sensor system already achieves the accuracy of the near-infrared sensor system and that the accuracy of the near-infrared sensor system is expected to be exceeded as early as 2021. By using the attenuated total reflection, the MIR sensor system is sensitive to sedimentation processes, which poses a certain challenge, but also has advantages. The development of software tools for processing large amounts of data bring benefits to big data technologies in agriculture. The Data Qualifier developed in the project enables the processing of large amounts of data and offers a competitive advantage in the development of chemometric models. The prototype of the measuring station developed in the project will be further developed, adapted to customer and project-specific requirements and thus be multipliable and can be commercially exploited. The software MIRscanLab is used on spectrometer systems for individual measurements, e.g. in measuring cases. The chemometric models for cattle and pig manure as well as digestate will be further developed. The system will be offered commercially as soon as the requirements for robustness aas well as accuracy have been met and the legal framework has been clarified."
