An agricultural system comprising a communication system configured to obtain: historical crop state data indicative of historical values of crop state indicating orientation of the crop stems or stalks relative to the ground; historical agricultural characteristic data indicative of historical values of an agricultural characteristic; and seasonal data indicative of geolocated seasonal values of the agricultural characteristic corresponding to a current season; and a predictive map generator configured to generate a functional predictive crop state map of a field to be harvested by an agricultural work machine , the functional predictive crop state map mapping predictive crop state values to different geographic locations in the field to be harvested based on the historical values of crop state and the historical values of the agricultural characteristic and based on the seasonal values of the agricultural characteristic at those different geographic locations, the predictive crop state values indicating one or more of a magnitude of crop lodging of the crop at the field and an orientation of the crop at the field; a geographic position sensor configured to detect a geographic location of the agricultural work machine ; and a control system configured to generate a control signal to control a controllable subsystem of the agricultural work machine based on a detected geographic location of the agricultural work machine and based on the functional predictive crop state map . a communication system configured to obtain: historical crop state data indicative of historical values of crop state indicating orientation of the crop stems or stalks relative to the ground; historical agricultural characteristic data indicative of historical values of an agricultural characteristic; and seasonal data indicative of geolocated seasonal values of the agricultural characteristic corresponding to a current season; and historical crop state data indicative of historical values of crop state indicating orientation of the crop stems or stalks relative to the ground; historical agricultural characteristic data indicative of historical values of an agricultural characteristic; and seasonal data indicative of geolocated seasonal values of the agricultural characteristic corresponding to a current season; and a predictive map generator configured to generate a functional predictive crop state map of a field to be harvested by an agricultural work machine , the functional predictive crop state map mapping predictive crop state values to different geographic locations in the field to be harvested based on the historical values of crop state and the historical values of the agricultural characteristic and based on the seasonal values of the agricultural characteristic at those different geographic locations, the predictive crop state values indicating one or more of a magnitude of crop lodging of the crop at the field and an orientation of the crop at the field; a geographic position sensor configured to detect a geographic location of the agricultural work machine ; and a control system configured to generate a control signal to control a controllable subsystem of the agricultural work machine based on a detected geographic location of the agricultural work machine and based on the functional predictive crop state map . <EOS>
