    For compost you need part green, part brown and part vegetable parts. Decomposition of organic materials in your compost pile is greatly increased when you create the proper balance between the carbonaceous materials (called BROWN because they are dry) and the nitrogen-rich materials (called GREEN because they are more fresh and moist).

    In compost lingo, this balance is referred to as the Carbon-Nitrogen ratio, and shown as C:N.

    Now, it is true that most people simply don't give a hoot about this scientific hocus-pocus stuff. Waste is waste! And when you just want to throw the stuff away, you're not inclined to stop a moment to ask, "Gosh, is this Carbon or Nitrogen?"

    And much of the sleight of hand of composting, whether you are aware of it or not, has to do with the organic materials' content of Carbon and Nitrogen. Blow this stuff off and you might get a surprise when you open the lid to your bin: it may reek to holy hell, like rotten eggs or ammonia, or it may just be sitting there doing absolutely nothing! Which is to say your pile has become a cold couch potato, and it ain't going nowhere fast!

    So, back to this necessary balance between the Carbon content of your waste material and the Nitrogen content. For best performance, the compost pile, or more to the point the composting microorganisms, require the correct proportion of Carbon for energy and Nitrogen for protein production. Compost scientists have determined that the fastest way to produce fertile, sweet-smelling compost is to maintain a C:N ratio somewhere around 25 to 30 parts Carbon to 1 part Nitrogen, or 25-30:1. If the C:N ratio is too high (excess Carbon), decomposition slows down. If the C:N ratio is too low (excess nitrogen) you will end up with a stinky pile.

  • Hi Clare - YAY my composting friend and son! Here's a great 101-style article on getting started with composting and everything you ever need to know. Also how we DIY'ed building our compost bin. My Stepson built it for a Boy Scout merit badge. Hope this all helps and happy composting! Hugs, Holly
