NIRS

Analytical technique based on the concept of electromagnetic radiation absorption by organic matter.

 

 

 

A field portable NIRS (ASD Inc. and Phazir) allows the evaluation of forage quality or soil fertility directly on the farm. This action aims to develop and disseminate this type of tool for resource management in real time, as well as rationing ruminants or correct fertilization of agricultural fields.

 

 


The practical implementation of portable NIRS tool requires a preliminary calibration phase and the validation of results. The calibration of the tool requires the collection of a large number of spectral measurements in the field (forage and soil) coupled with chemical analysis carried out with traditional laboratory methods.




The ARChE_Net project purchased two portable NIRS. Their calibration has been done with the help of a spectrometry expert, Pierre Dardenne (CRA-W, Gembloux). A microNIRS will be acquired as part of the ECLIPSE project to facilitate multiple field surveys.

 

 

 NIRS is an analytical technique based on the concept of electromagnetic radiation absorption by organic matter. This technique allows a fast, frequent and inexpensive evaluation (prediction) of the chemical composition of various types of organic samples (fodder, fertilizers, soil, etc.).
