Development and validation of a quality assurance system for mobile NIRS systems for measuring nutrient concentrations in liquid farm manures (NIRS-QS)
Project
Project code: 2820ABS101, 6369
Contract period: 01.11.2020
- 31.10.2023
Budget: 499,985 Euro
Purpose of research: Applied research
Keywords: crop produktion, fertilization
Farmers and contractors expect that the mobile NIRS analysis of liquid organic fertilizers will be approved in order to fulfil the documentation requirements under the new German fertilizer ordinance and the organic fertilizer shipment regulation. This requires the development of a test procedure for NIRS sensors in use for the application of liquid fertilizers in order to be able to permanently ensure the quality of the measuring accuracy and the repeatability. With the implementation of the project, the basis for a nationwide approval of NIRS sensors for the determination of the nutrient content in liquid fertilizers is to be achieved. A system will be established in which the devices will be inspected at regular intervals (two to three years) similar to the regular check of field sprayers. The approval is the responsibility of the respective Länder services responsible for the fertilizer ordinance. In order to achieve the quickest possible implementation after project completion, the most important country departments, in addition to representatives from science and consulting, are already involved in the discussion of results during project implementation, and possible application strategies are discussed. With the implementation of the project, the NIRS tool will serve the users and marketers of liquid fertilizers to record the nutrient contents in liquid fertilizers simply but scientifically soundly. At the same time, the project will help to improve the accuracy of the quantities of nutrients applied through continuous real-time analysis and to provide a transparent view of the flow of goods when marketing fertilizers.
