Picture from Sue Colucci's blogSue Colucci, area specialized extension agent for Henderson, Buncombe, and Haywood counties, is working with a farmer who is having problems with herbicide carryover in manure. She worked with him to perform the bioassay that I have described to you several times. She just published those results, with pictures, on her blog. I urge you to read this over and bookmark it so you can find it again. Here's the link:
Great job, Sue. Thanks!
This is a reminder to be very cautious about the use of manure and compost for your garden and farm. They can be wonderful additions to the soil; I personally use them all the time. But you need to know the history of the materials. We have a publication on this topic that covers it indepth. It is located on my ncorganic.org website at http://tinyurl.com/y9a3eqh. We have just revised and expanded that publication. It is in its final stages of preparation and should be available real soon.
