Search Tips
You can search the database in several different ways (see links above). An explanation of each approach can be found below the link
USAGE SEARCH

Select a specific commodity, active ingredient and use statistic. Provides a color US map, by state, of the statistic average requested (over all years) (not yet implemented).
GRAPHICAL REPORTS
Creates a Chart. Select a State, a Crop, a active ingredient, and Use Statistic. Results are presented as a line or bar chart of mean use statistic values.
STATISTICS SEARCH
Because the data provided by NASS are already grouped by state, crop, active ingredient and year, we can not calculate statistics for a single crop, state, active ingredient, and year. However, the following three ways can be used to search and calculate statistics:
Search by Year
-Select a specific active ingredient and year. Returns all active ingredient use statistics by commodity and year as web table or Excel spreadsheet. Results can also then be seen as bar chart, by year, of selected statistic and commodity, if requested (to be implemented).
Search by State
-Select a specific active ingredient and state. Returns all active ingredient use statistics by commodity and year as web table or Excel spreadsheet. Results can also then be seen as bar chart, by year, of selected statistic and commodity, if requested (to be implemented).
Search by Commodity
- Select a specific active ingredient and commodity. Returns all active ingredient use data by state and year as web table or Excel spreadsheet. Results can also then be seen as bar chart, by year, of selected statistic and state, if requested (to be implemented).
