Soil Erosion and Carbon Redistribution Model for Iowa Fields

Model predictions of soil erosion and soil organic carbon redistribution from 1859 to 2019. The dataset was developed by NASA and applied to three paired prairie grassland and field sites in Iowa. It integrates a soil organic carbon mixing model with a landscape evolution model to simulate tillage erosion.

Use Cases

• Analyzing historical soil organic carbon loss and deposition patterns.
• Modeling the impact of tillage erosion on agricultural field topography.
• Comparing soil carbon stocks between cultivated fields and native prairie grasslands.
• Calibrating landscape evolution models with soil carbon transport data.
• Assessing long-term agricultural sustainability and soil health trends.

Strengths

• Covers a 160-year time range from 1859 to 2019.
• Model integrates two specific components: a SOC mixing model and a landscape evolution model.
• Applied to three distinct paired sites in Iowa for comparative analysis.
• Cross-platform presence on Data.gov and NASA Earthdata indicates recognized importance.

Limitations

• No column names or row counts are provided by any source, obscuring data structure.
• Conflicting 'last updated' dates: Data.gov shows 2026-03-12, while NASA Earthdata shows 2019-08-01.
• License is unclear, listed as 'other-license-specified' on Data.gov but 'None' on NASA Earthdata.
