Hello,

We are using planet images to control irrigation in crops.
We usually use SWIR bands with other satellites.
Is there a way to see  a crop hydric state, or something similar with planet available bands?

Hi @azcuemaite, 

Thanks again for question! I have some documentation here that may help you. As well as an informational PDF on Soil Water Content. Please let me know if this helps answer your question.

Hi, 
Depending on the level of water stress, you can also rely on vegetation indices such as NDVI. In this paper, Planet-based NDVI was used to monitor water potential in grapes. 

We also have the biomass proxy which is a 10-m product based on the combination of Sentinel-1 and Sentinel-2 data. It’s signal is mostly derived from vegetation water content (VWC). If you’re interested in learning more, feel free to reach out. My email is ariel.zajdband@planet.com.
