A near infrared spectroscopy calibration for the prediction of fresh grass quality on Irish pastures

Information Processing in Agriculture, 2022
The aim of this study was to develop near infrared spectroscopy (NIRS) calibrations to predict quality parameters, dry matter (DM, g kg−1) and crude protein (CP, g kg−1 DM), in fresh un-dried grass. Knowledge of these parameters would enable more precise
