Abstract: An information map is obtained by an agricultural system. The information map maps values of a characteristic at different geographic locations in a worksite. An in-situ sensor detects nutrient values as a mobile material application machine operates at the worksite. A predictive map generator generates a predictive map that maps predictive nutrient values at different geographic locations in the worksite based on a relationship between values of the characteristic in the information map and nutrient values detected by the in-situ sensor. The predictive map can be output and used in automated machine control.

Abstract: An information map is obtained by an agricultural system. The information map maps characteristic values at different geographic locations in a worksite. An in-situ sensor detects values of a crop characteristic as a mobile machine operates at the worksite. A predictive map generator generates a predictive map that maps predictive values of the crop characteristic at different geographic locations in the worksite based on a relationship between the values of the characteristic in the information map and the values of the crop characteristic detected by the in-situ sensor. The predictive map can be output and used in automated machine control.
