Corn silage, widely used as a feedstock in anaerobic digestion systems, plays significant role renewable energy production. The measurement of the biochemical methane potential (BMP) ensiled corn at farm level is utmost importance for characterizing its production and optimizing biogas generation. Thus, understanding BMP silage from individual farms crucial efficient plant management proper utilization this valuable resource. study aimed to assess using cost-effective miniaturized handheld NIR spectrometer with minimal sample preparation. Twenty-nine wet samples many dairy located Lombardy (Northern Italy) were used. calibrations developed by means partial least-square (PLS) regression obtaining models fairly good coefficient determination (R2C = 0.92 R2CV 0.80 DM R2C 0.90 0.75 BMP) reasonable prediction error (RMSECV 1.38 4.76 BMP, respectively). Based on these results, would be useful providing fast screening dry matter (DM) level, enabling plants rapid turnaround advisory systems.
