Claim 15:
16. An agricultural system comprising:
a communication system that receives a prior vegetative index map that indicates vegetative index values corresponding to different geographic locations in a field;
a geographic position sensor that detects a geographic location of an agricultural work machine;
an in-situ sensor that detects, as a biomass characteristic
corresponding to the geographic location, a force used to drive a threshing rotor and generates a sensor signal indicative of the force used to drive the threshing rotor;
a processing system that receives the sensor signal and is configured to identify, as a value of the biomass characteristic, a value of the force used to drive the threshing rotor;
a predictive model generator that generates a predictive biomass model that models a relationship between the vegetative index values and values of the biomass characteristic based on a vegetative index value in the prior vegetative index map at the geographic location and the value of the biomass characteristic detected by the in-situ sensor corresponding to the geographic location; and
a predictive map generator that generates a functional predictive biomass map of the field based on the vegetative index values in the prior vegetative index map and based on the predictive biomass model, the predictive biomass map mapping predictive biomass characteristic values to the different geographic locations in the field.
