Use the Rotation Name dropdown list to select an existing rotation template. SnapPlus comes with a sample farm database that already has a sample rotation set up.

Use the button to create a new rotation for editing. You will be requested to type in a name for the rotation. If the rotation will use farm specific nutrient sources, then include a reference to the farm in the name. Note that the rotation name can be changed at any time by typing in the dropdown list. To see a list of crop abbreviations, click on the Crop Abbreviations button. A list will be displayed that includes only the crops that you included on the Farm screen. For a full list of crop abbreviations used in SnapPlus, see A Guide to Crop Abbreviations.

To use a current rotation that you have created with another farm, use the Share button located above the rotation list. First, you will be prompted for a Save As rotation name, if you want to change it. This dialog box can also be accessed by going to the Import/Export menu and selecting Rotations under the Export section. When you have the new farm open, from the Import/Export menu, select Rotations in the Import section. Then you can rename the rotation if you want. The information about the rotation and farm source will be displayed. If the information is correct, then click on the Import to SnapPlus button. Importing a rotation will add the rotation details to your farm and any subsequent editing of the rotation will not affect the rotation details in the original shared farm.
