New estimation strategy improves soil carbon sampling in agricultural fields

Researchers have evaluated strategies for efficiently estimating soil organic carbon in agricultural fields. Quantifying soil organic carbon stocks in agricultural fields is essential for developing sustainable management practices and monitoring. The research team found that in a typical Midwestern agricultural field, public soil surveys and satellite imagery can be leveraged to efficiently select sample locations. This may reduce the number of samples needed to achieve a given precision (compared to random sampling).
