Situation
Growers​ ​can​ ​use​ ​their​ ​TerrAvion​ ​thermal​ ​and​ ​NDVI​ ​imagery​ ​to​ ​identify​ ​irrigation​ ​system​ ​failures​ ​in​ ​their
fields.​ ​In​ ​this​ ​example,​ ​inefficient​ ​flood​ ​irrigation​ ​flow​ ​left​ ​the​ ​south​ ​part​ ​of​ ​this​ ​field​ ​water​ ​stressed.​ ​The
imagery​ ​reveals​ ​the​ ​problem​ ​on​ ​August​ ​3,​ ​early​ ​enough​ ​to​ ​make​ ​an​ ​effective​ ​correction.​ ​The​ ​grower,
however,​ ​missed​ ​the​ ​signs​ ​and​ ​the​ ​inefficient​ ​irrigation​ ​flow​ ​compromised​ ​yield​ ​in​ ​the​ ​10-acre​ ​water
stressed​ ​area​ ​as​ ​can​ ​be​ ​seen​ ​in​ ​the​ ​September​ ​8th​ ​imagery.
Action
Use​ ​thermal​ ​and​ ​NDVI​ ​imagery​ ​to​ ​catch​ ​irrigation​ ​failures​ ​and​ ​make​ ​corrections​ ​early​ ​enough​ ​to​ ​limit
negative​ ​effects​ ​on​ ​yield.
