picloram and grazeon?
Hello, this is my first post to this forum and I'd like to thank all of the contributors over the last year. I've poured through this archive and learned alot that's allowed me to be successful at vermicomposting so far. In the future, I'll make a detailed post about what I'm doing and include pictures.
My question is this. My herd lives off of restaurant vegetable scraps and leaves that I collect in fall. My small farm is growing and I'm experimenting with outdoor windrows. I hear again and again that manure is an excellent source of worm food and having a large amount of worms/compost appeals to me. Being able to bring in truckloads of curing horse or cow manure and feed it to the worms and harvest later for free sounds wonderful. This biomass would be a great input.
My concern is picloram and grazeon. In Austin this past summer we had a bad drought. Farmers were importing hay from farther and farther away and these broadleaf weedkillers are sometimes sprayed on fields where hay is harvested. The problem I'm told is that both of them pass through the animals without being broken down and even hot composting the manure will give you perfectly good compost that you can't grow vegetables in. It's still in the compost and still an issue.
I know of no one off hand that uses manure as a source of compost materials here locally due to this. I do know that large scale nurseries that sell compost test for picloram and grazeon but the tests are expensive and apparently not reasonable for a backyarder like myself.
This leads me to...worms and bioremediation. I've seen videos that show how earthworms are being used to clean land as part of bioremediation. I've also heard that ef's or redworms will clean things like lead out of the materials they consume. So, my question is...if I'm doing these large outdoor windrows and add some manure, if picloram or grazeon are present will the worms deal with it? I would only harvest once every 6 months or so and have plenty of time for them to consume the material. Need I worry about these two weedkillers?
Thanks in advance for any input!
