A method for baling and an agricultural baler (10) are provided for determining the fraction of hay at various moisture levels during an agricultural baling process. A moisture sensor array (46) is provided on an agricultural baler (10) to sense the moisture content of incoming crop material (42) as the baling process progresses. The moisture sensor array (46) is connected to an ECU (40) that is programmed to determine the ratios of incoming crop material (42) that are at or above particular moisture content levels. An indication is given to the operator by way of an operator output device (50, 52, 54) regarding the moisture content ratio.
