Paper Summary

The study looked at how soil organic matter varies across different areas in a county. By analyzing data from soil samples, researchers found that the number of samples taken doesn't affect how soil nutrients are distributed. They discovered that around 400 samples are needed to accurately predict soil organic matter levels in a county.
