Since when and by when can I adopt a new regenerative practice to meet the additionality requirement?

Typically, you can meet the additionality requirement during the current growing season, even if it was prior to signing your contract. You can also meet the additionality requirement on a given field via changes made on the field in the previous 24 months from enrolling. Whenever you made a practice change, either in the first year of enrolling or in the 24-month lookback period, that date would be the field’s “start date” for any historical data requirements.
