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