If your practice change was related to cover crops, you will be asked to provide supporting documentation for your cover crop-related events. For cover crops terminated via winter kill, here is a guide for how to use Weather Underground as a source of documentation.

Step 2: Type your location into the search bar and select the correct option from the results:
Step 3: Click on "History":
Step 4: Select "Weekly" and type in the date on which the winter kill occurred, then click "View". Hovering your mouse over the date will show the Max/Avg/Min details.
