COMET-Farm’s Crop Rotation Builder feature allows users to create a baseline using a subset of crops that have “templates” pre-populated with typical management practices. These templates include data like standard planting and harvest dates and fertilizer application rates. Plus, when users add these template crops to their rotation, they are given the option to apply a standard tillage as well as a standard irrigation. Users can then modify or remove any default management applied by the crop template.


Using the crop rotation builder will populate the entire baseline, overwriting any existing crop management that was previously added to the field. Crops will populate the rotation in the order they are added. For example, in the below example, the baseline will be populated with a corn-soybean rotation. Cover crops, when selected, will be added as a second crop in the same year. Follow the guide below for more information.



Crop Rotation Builder Guide

1

Crop Selection. Select at least 2 crops to include in the rotation. This subset of crops includes those populated with typical management practices, so not every COMET-Farm crop is available. To populate the baseline with a single crop (e.g., grass), select the same crop twice.

2

Irrigation. Indicate whether the selected crops are irrigated or non-irrigated. If “irrigated” is selected, typical irrigation rates will automatically be applied to the associated crop.

3

Tillage. Select pre-planting and post-harvest tillage system intensities for the selected crop. Options include No Till (III), Reduced Till (III), Full Intensive Till (III), and None. For information on what these tillage intensities mean, see the Tillage System Intensity and Other Field Operations section.

4

Optional: Add Crop. To include another crop in the rotation, click +Add Crop. The baseline rotation will be populated with crops in the order that they are listed. For example, if Corn, Winter Wheat, and Soybean are added to the crop rotation builder in that order, the baseline will populate as Year 1 - Corn with Winter Wheat as a cover crop; Year 2 - Soybean; Year 3 - Corn with Winter Wheat as a cover crop, and so forth.

5

Optional: Delete Crop. Use the trashcan icon to remove a crop from the rotation.

6

Save. By clicking this, the crop rotation will be applied to the entire baseline, overwriting any existing crop management that was previously added to the field. This action cannot be undone.
