Description: These layers show crop shares (from 2001-2009) for each county for corn, sorghum, and conservation reserve program (CRP).
The data source for the crop shares is from FSA (Farm Service Agency) and includes years 2004 through 2009. Only planted acres of each of the crops is recorded in the crop share calculations. Prevented and failed acres are not included here. The reason for this is to help assess farmers’ decisions regarding which crops they will plant.

Description: These layers show crop shares for corn. For each county, the "Corn - Mean" layer shows the mean among all 9 years (2001-2009) of the ratio of planted corn area to total county area. Each of the annual layers ("Corn - 2009" and so on) show the deviation from the mean crop share for that particular year, which is presented as a percentage of the mean crop share for corn in the given county.

Description: These layers show crop shares for sorghum. For each county, the "Sorghum - Mean" layer shows the mean among all 9 years (2001-2009) of the ratio of planted sorghum area to total county area. Each of the annual layers ("Sorghum - 2009" and so on) show the deviation from the mean crop share for that particular year, which is presented as a percentage of the mean crop share for sorghum in the given county.
