Disclosed herein is a method and apparatus for analyzing statistical data for a region of a farming field defined by a boundary on a set of georeferenced agricultural maps of the field. Input data includes digital maps of the field which represent spatially-variable characteristics. The characteristics may represent soil properties, crop properties and farming inputs applied to the field. The characteristic data is georeferenced to specific field locations by longitude and latitude coordinates. An electronic display is used to display a visual map of the field together with a visual representation of a first characteristic of the field. An input device is used to draw a boundary around an area of the display, thereby defining a geographic area of the field. Analysis of a second characteristic of the field which correlates to the defined geographic area is then performed. Typically, a farmer draws a polygon on the display based upon similar characteristic values and calculates crop yield and moisture content within the geographic area defined by the polygon.
