If you’ve encountered unusual materials, products or approaches to manure and soil additives or plant growth stimulants recently, a new non-conventional additives guide from the University of Wisconsin may help decipher what’s going on. In it, researchers have identified a variety of products and approaches atypical of conventional agriculture.
The guide lists 600 products. And it details what they contain, what claims have been made about them, what research has been done with the product and where the research is available.
For more information, call the UW-Madison soil sciences department at (608) 263-2795. Or visit the Web site: www.soils.wisc.edu/extension to download a copy of the guide.
