Is there a way to add soil sample data into SWAT+ within FieldPrint Calculator?

This is a planned feature. There are two short notes in the Soil Carbon documentation about this:

• We are currently assessing how to use soil samples to refine SWAT+ modeling runs. We plan to release recommendations at a later date in 2026. Learn more on the metric documentation site.
• Baseline soil carbon measurements are crucial for establishing a starting point for sequestration calculations. Project owners are responsible for conducting soil sampling for the fields enrolled in their supply chain programs. In 2026, we anticipate that soil organic matter sample data for individual fields will be able to be entered into the SWAT+ model for more accurate estimation of soil organic stock changes.
