As of right now, not in any accurate way. What it can be used for is measuring canopy.

With that said, as camera systems and machine learning improve, this will soon be possible.

I have seen some research on this topic. In this article, “Assessing Cover Crop Biomass Using Aerial Imagery: Lessons Learned During the UNL-NRCS Soil Health Initiative,” there’s some preliminary data reported and the conclusion that NDVI values don’t perfectly correlate with cover crop biomass, but some insights can still be gained.




“NDVI sensors can … be used to estimate cover crop biomass. … Although NDVI and biomass values might not align perfectly and the response might not always be linear, the relationship described here provide us some helpful insights on cover crop management considerations that affect biomass production such as planting time, seeding rate and method (broadcast or drill), species in the mixture (single or multi-species), herbicide program for cover crop termination, and grazing opportunities.”
