Compared to the optical-only model, InSAR coherence improved biomass estimations by 4% in wheat, 5% in triticale, and by 11% in cereal rye.  ...  However, these results were season- and species-specific (R2 = 0.74, 0.81, and 0.34; RMSE = 1227, 793, and 776 kg ha−1, for wheat (Triticum aestivum L.), triticale (Triticale hexaploide L.), and cereal  ...  Vegetation exhibits strong volume scattering; thus, cross-polarization backscatter has been shown to be well correlated with total biomass in wheat (Triticum aestivum L.) and soybeans [38, 39] .  ...
