After the rash of organic and sensitive crops being mistakenly sprayed by aeriel spray planes (not to mention the large crew of field workers as well), IDALS, the Iowa Department of Agriculture and Land Stewardship, has implemented a sensitive crops directory that aeriel sprayers are asked to consult before spraying.
The department provides the signs at a discount and leaves it up to handymen like myself to figure out how to get the sign 8-10 feet off the ground with the sign at a 30-40 degree angle from the post. I just bought a heavy piece of 10 ft PVC vent pipe andÂ a 45 degree elbow. I cut about two feet off the pipe, mounted the sign to the small piece then connected the two pieces with the elbow. Then I drove a steel fence post into the ground and just slipped the PVC pipe over it. I’m hoping I can get away with not attaching it to the post so I can slip it off in the winter to spare the sign and PVC some weathering. Â The PVCÂ seems heavy enough and puts enough torque against the post that it doesn’t seem to want to spin around at all.
