Accurately estimate fiber concentration and optimal harvest timing in stands of pure grass, pure alfalfa, and alfalfa-grass mixes in New York State.
Provide forage height measurements, planned stubble height, expected weather, botanical composition (mixed stands), grass species (pure grass) and target NDF at harvest (pure alfalfa and pure grass).
Estimation of current NDF, target harvest height and days to harvest to obtain optimal quality.
