Can I use the organic matter percentage from my soil sample?
Discussion on why organic matter percentage is not used in soil samples.
- Enrollment in Encirca Premium.
- Farm and Fields created.
- Crop assigned to a field.
- Yield goal set.
- Indicate the field's tiled status.
- Nitrogen plan template created and applied to a field.
No. This approach has not yet been tested. While it seems like a natural thing that we should do, we want to ensure that we have a good approach to interpolating the soil test results to the field decision zones. We are also evaluating the algorithm for converting organic matter to organic carbon, which is what is used in the model, as well as evaluating alternative soil test methods for deriving organic carbon more directly. Additionally, organic matter is measured only in the plow layer for standard fertility sampling. Crop models consider the mineralization of organic matter throughout the soil profile, though getting the surface correct would be an improvement.
