In this box, you can edit Manure or Biosolids names and nutrient types.

For example, you can select the source Graze, and modify it from Dairy, grazing to Beef, grazing. These changes affect all crop years.

If a nutrient source is no longer in use and is replaced with a new source, you must create that new source using the Add button on the Nutrient Sources screen. If you try to change the name to an existing source name, you will be notified that the name is in use and you will have the option to merge the two sources into one source.
