What is the estimated runoff from rainfall events?
Requirements:
- 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.
Answer:
Runoff is affected by the curve number associated with the SSURGO soil data for the map unit with other soil parameters such as texture and soil saturation level from the previous day. A high curve number indicates more runoff whereas a lower curve number indicates more infiltration or ponding (depending on saturated flow speed). The curve number and the other soil parameters are the same for the entire soil polygon so they do not account for landscape variation at smaller scales.
