While it is far too early to provide a definitive estimate of the losses that have occurred to Georgia agriculture from Hurricane Michael, here are a couple of articles which start to gather information about how bad the losses could be.
The Southeast Farm Press reported here that Michael caused significant damage to cotton, peanuts, pecans, and vegetable crops as well as causing a lot of property damage, including damage to aerial applicator aircraft hangars, chicken houses, cotton gins and homes. Some peanuts that were dug but not harvested could also have been affected, although peanuts that are still in the ground may be able to be harvested. The rain may have helped loosen the soil, making them easier to dig when it is time. In a separate article here, losses were estimated at $1 billion.
The Packer wrote that 84 chicken houses, estimated to contain more than 2 million chickens, were destroyed by the storm. Early estimates of losses could go as high as $2 billion, although it will be a long time before a complete assessment is done. You can read the story here.
