Photograph of gully control. This area was previously badly eroded with a deep gully. Gully was filled and shaped with a bulldozer then fertilized with 175 pounds per acre of 10-20-10 grade fertilizer and sprigged to Bermuda grass.

Work planned and supervised by SCS technicians. Work Unit Conservationist T.J. Davis in the picture. ok-730-10.
