- •
Remote estimation of soil organic matter content (SOMC) in the Sanjiang Plain.
- •
Optimal band algorithm (OBA) was developed for assessing SOMC using spectral data.
- •
Grey relational analysis (GRA) was used to select the sensitive spectral parameters.
- •
We compared the performance of proposed models using GRA-ANN and OBA.
- •
Combining different algorithms may improve SOMC estimations on a regional scale.
