Green snap damage in corn
Flown by Andrew Westfall, Agriculture & Natural Resources Educator, Purdue Extension – White County
A severe storm passed through White County, Ind. in July 2020, causing wind and hail damage to corn. UAV images were used to compare with a crop insurance assessment to evaluate crop loss.
Stitched aerial image from August 13, 2020. 
Plant health image collected on August 13, 2020. 
Images of the field were collected on July 28, August 13 and September 8 of 2020. The farmer planted a different variety approximately halfway through the field, and they found the variety more susceptible to wind damage was used on the border rows. Note: The northern panhandle portion of the field was protected by a windbreak and buildings.
Using the "plant health" map feature in Drone Deploy, they determined that approximately ten acres (+/- two acres) were severely damaged by wind. Mid-August seemed to provide the most accurate assessment and hybrid selection played a large role in withstanding high winds.
