The authors review the methodological background of NIR forage analysis, with particular attention to database structures and size, inconsistencies among chemical reference methods, and the need for harmonization. The advantages and limitations of NIR spectroscopy and classic ’wet’ chemical analysis are critically compared. Applications of NIR technology across harvesting, preservation, and feeding processes, including in situ measurements, are presented. The paper emphasizes a comparative evaluation of globalized NIR laboratory networks versus locally developed, customized NIR databases, highlighting their respective strengths, limitations, and interdependencies. The benefits and risks associated with reliance on global NIR networks are discussed in contrast to local calibration development.Furthermore, the study examines the relevance of specific NIR parameters to key agricultural domains, including crop production, machinery operation, livestock management, feed formulation and veterinarian aspects. The role of global NIR laboratory networks in improving efficiency across forage production, harvesting, storage, and feeding is highlighted. Parameter sets and performance outcomes of selected global NIR networks are compared.
