How Satellite Imagery Helps Advance Regenerative Ag Practices
Gradable is building programs that reward producers for their regenerative practices.Farming sustainably means protecting the natural resources a farm relies on while running a healthy business. Gradable programs help farms improve nitrogen use efficiency, reduce greenhouse gas emissions, increase soil nutrients, and expand farmer profit potential.
For decades, grain producers have led the charge with regenerative practices like cover cropping, removing or eliminating tillage, rotating crops, incorporating livestock, and promoting biodiversity. And there are more opportunities for sustainable agriculture on the horizon.

Streamlining verification & opening up new markets for farmers
Gradable’s technology also makes verification of practices—usually time consuming and expensive—easier for growers. Machine learning and satellite imagery allow Gradable to analyze millions of acres of crop production data to support and verify crop production data.
How does it work?
Satellite imagery combined with precipitation and temperature data helps Gradable verify cover cropping and tillage—both essential regenerative practices. We’re able to identify cover cropping with 96% accuracy (see Figure 1).
Figure 1. Sentinel-2 satellite imagery and Enhanced Vegetative Index (EVI) data show the difference between fields with and without cover crops.
Gradable technology is also able to correctly classify conventional tillage, reduced tillage, and no-till with an average accuracy of 77%—and 84% accuracy when classifying no-till (see Figure 2).

Using satellite imagery and leading-edge farming technology, Gradable is helping reduce the costs and time associated with verification for producers to take advantage of new markets for sustainably grown crops. Gradable verification can help reduce or eliminate the need for on-site visits while maintaining high levels of accuracy.
