Hail Damage case study
Growers can use TerrAvion imagery to help assess storm damage in their fields. In this example, the August 3 NDVI image shows damage from a recent hailstorm. The low vigor areas have suffered damage from the storm, which were confirmed through in-field scouting in affected areas. Growers can use the the histogram tool to quantify the extent of crop damage in their fields (e.g., 43% of this field suffered hail damage).
Use imagery to help quantify crop damage and to make informed decisions regarding insurance claims or potential crop recovery options.
1. After a storm, review the first series of post-storm images.
2. Look for low vigor zones. Stressed, damaged plants will appear as low vigor spots
3. If the low vigor zones you have identified as weather damage, consult with your agronomist to determine if replanting or a nutrient application are viable corrective actions.
a. If you decide to replant, use imagery to identify a target area
i. Draw and export shapefiles of the target area in OverView and upload into prescription program
ii. Create target treatment zones in TerrAvion affiliated precision ag platform
b. If you decided to make a nutrient treatment, consider a target spot treatment or variable rate application
i. If spot treatment, use imagery to identify a target area
1. Draw and export shapefiles of the target area in OverView and upload into prescription program
2. Create target treatment zones in TerrAvion affiliated precision ag platform
ii. If variable rate treatment, use imagery to create prescription zones
1. Draw and export shapefiles in OverView and import into prescription program
2. Create prescription zones in TerrAvion affiliated precision ag platform
c. Use imagery to monitor the performance of replanted areas or nutrient applications
i. Use information to determine if additional nutrient applications are required
