As Robin says we will get always better results drying the samples, because we can make it more homogeneous, after grinding, anyway there is a bigger need to analyze the forage fresh, to get quicker results and decisions.
When working with fresh forage samples (due to the high moisture content), it is important:
1: Take a representative sample.
2: Homogenize the sample correctly.
3: Place it in a large cup configured to acquire different subsamples
4: As soon as you scan the sample, analyze it in the Lab for reference data (the same placed in the large cup) and link the lab values to the spectra.
5: Include the variability of temperature in the model.Temperature in change along the year, so in this case a repeatibility file can help to make the model more stable to this changes.
6: Of course, the quality of the Lab analysis is very important.
