New Select a Method Flyer

There are a number of ways to compost. This flyer will help you decide.

Learn About Bokashi Composting

Have you heard about Bokashi composting? It's a method developed in Japan that is inexpensive, easy, takes up little space, has no smells, doesn't attract pests, and requires no turning. The method makes it hard to find an excuse not to compost your kitchen waste! You can compost all the kitchen scraps you normally compost as well as meat, bones, and oily things. Jill Van Nortwick recently gave a talk to BERNCO master composters about Bokashi composting. Check out these powerpoint slides from the talk. Or, if you prefer, here is a PDF copy of the slides. The slides include a video about Bokashi composting. The video is made by a commercial company but keep in mind that you can do Bokashi composting in ordinary buckets.

New Herbicides Imprelis and Aminopyralid Can Contaminate Compost

Up till recently, herbicides commonly used in the home yard or garden did not contaminate compost since they break down in the composting process. However, the US Composting Council is warning us about a new herbicide, Imprelis from DuPont, which can survive the composting process and harm plants which are later grown in the compost. Care should be taken to avoid putting plants which have been treated with Imprelis into compost. Please see article from the Composting Council for more information. In addition, the herbicide Aminopyralid marketed by Dow AgroSciences, bearing brand names including Milestone and Forefront, remains active in horse manure up to three years. See article from BioCycle magazine, The Aminopyralid Challenge Continues. Update: DuPont has announced that it plans to issue a total recall of Imprelis following widespread evidence and complaints that the product has caused the deaths of trees around the country. See report in Beyond Pesticides Daily News Blog.
