Systems and methods for optimizing the collection of a windrowed crop are described. In an exemplary implementation, conditions data is accessed and used to estimate the moisture content of a windrowed crop. The estimated moisture content is used to create an optimal collection prescription for the operation of baling equipment to collect the crop. During the collection of the crop, the moisture content of the crop is measured and compared to the estimated moisture value. The system may then revise the optimal collection prescription based on the measured moisture value. This process can then be repeated until all of the windrowed crop is collected.
