I'll list a few that I know and keep the greens and browns in separate lists for easy reference. The simplest method for determining the correct compost ratio is to maintain a 2:1 ratio of browns to greens. Compost Tea Ingredients and Biological Food Sources. Materials High in Carbon C:N autumn leaves 40–80:1 sawdust 200–750:1 wood chips or shavings—hardwood 450–800:1 wood chips or shavings—softwood 200–1,300:1 bark—hardwood 100–400:1 As we mentioned on our ingredients page, the ideal composting carbon nitrogen ratio is between 20:1 --> 40:1. 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 you have the right balance of nitrogen rich green material and carbon rich brown material - in other words a Carbon Nitrogen ratio of about 25 - there is at least some hope that you will succeed. That means if you’re working with grasses and leaves, add about 66% leaves and 33% fresh grass clippings. Composting Grass Clippings. Browns Greens Dry leaves […] Use 6 inches browns to 2 inches of greens. Recipes for making compost usually tell you to combine the browns and greens in the correct ratios. Composting is the process that turns vegetable scraps and other organic materials into lovely soil. The compost will radiate heat if it contains a good ratio of carbon to nitrogen while it cures. It would be a great help to me and probably to other rookies here to have a list on the sight for compost ingredients when I run low. Share this science project . Grass trimmings are the quintessential compost ingredient. Organic ingredients Good compost must have a balance of carbon-rich (woody material) and nitrogen rich (green leafy matter or manure) materials. If the C:N ratio is too low (excess nitrogen) you will end up with a stinky pile. Organic matter high in carbon — what composters commonly call browns — provides energy for decomposer organisms as they consume and break down the contents of your compost pile. Good compost is a balance of different ingredients, but essentially it comes down to the all important, but often misunderstood, carbon/nitrogen ratio. Planet Natural has a handy chart that list the carbon to nitrogen ratio of many common compost ingredients here. How to Compost Compost Ingredients. Compost is the very best food you can give to the plants in your garden. The recommendations usually go something like this: The ideal C:N ratio is 30 parts brown to 1 part green. As a good rule of thumb, a compost pile breaks down best when there is a ratio close to 2 parts of brown material (carbon), to 1 part green (nitrogen). A compost heap with a predominantly wooden carbon source will eventually lose the ideal carbon:nitrogen ratio, slowing the process down and causing it to become smelly. Along with a smaller ratio of green ingredients, brown compost works with air and water to speed the decay process. Compost; your #1 ingredient.

You need to fill in how many “parts” of each compost ingredient you are planning to add to your pile. Compost Ingredients. Do you have to be exact? To reach the ideal Carbon to Nitrogen ratio of 30:1 in the compost pile add equal parts of balanced nitrogen and carbon rich materials. Table 3–2. Using the calculator is very easy. But more than one composter has discovered, to his distress, that the grass he dumped into his compost pile, instead of decaying into a nice, dark, crumbly, humus-rich compost, has instead putrefied into a slimy, stinky mess. Table 1 shows the estimated C:N ratio for some common brown materials. For each recipe, mix the ingredients thoroughly and follow the directions in the next section, “Keeping your pile happy.” Depending on weather and compost ingredients, you should have finished compost … Of the many elements required for microbial decomposition, carbon and nitrogen are the most important. Carbon-rich materials are called brown materials, and … While there are many ingredients for compost, you can’t put everything in the compost pile. At the same time, woody materials can provide structure to the compost and … Composting can seem daunting. Depending on the amount of carbon and Nitrogen the ingredients of a compost can be classified into two categories Brown and Green. So, what’s it … The C/N ratio is how I determine brown from green. Without the proper mix, you may have a stinky pile … Maintain well-fed composting organisms with these varied ingredients. Although leaves will compost slowly by themselves, they can benefit from additional nitrogen. How To Create The Right Mix For The Perfect Compost Pile.

But before we delve into how much of each ingredient to use, here is a quick overview of the types of materials that we will be adding to our compost pile. In your terms look at it this way, compost is mostly filler, little mineral fertilizer. For this reason, it helps to become familiar with appropriate ingredients for compost. History.

They also need a balance of high nitrogen ingredients to high carbon ingredients, at about a ratio of about 1:25 Ingredients are added in layers in much the same way as you would make a lasagne. The ideal carbon-to-nitrogen ratio for a compost pile is 25 to 30 parts carbon for every 1 part nitrogen. Select the correct mix to give a carbon: nitrogen (C:N) ratio of about 30:1. Brown Compost "Brown" compost ingredients are those ingredients that have high carbon content. For more about using compost in potting mixes follow this link to Compost potting soil Composted Forest Products As a potting mix ingredients there is little difference between composted forest products and composted pine bark, mostly it is used as a cheap replacement for the peat component whose purpose is to provide drainage and air spaces within a potting mix. Basic compost ingredients are shredded paper, straw, dried leaves (carbon) and kitchen scraps, manure (chook, cow, horse) and green waste from the garden (nitrogen). Ratio of ingredients = [CN1 x (CNtarget-CN2)] : [CN2 x (CNtarget-CN1)] In principle we multiply the C:N ratio of the 1st ingredient with the difference between 2nd’s and target, then … If the C:N ratio is too high (excess Carbon), decomposition slows down. Some things, like meat and fats, are simply a no no, as they can lead to odors and bacteria buildup (of the unhealthy kind). Finished compost has a C/N ratio of 20 - 25:1. High quality compost, possessing a full-diversity of biology, is the key to brewing quality compost teas. Organic matter high in nitrogen — called greens — supplies the decomposers with protein. Composting 101 - How to compost, what to compost and what not to compost, compost bins and troubleshooting tips for common compost problems. Compost ingredients can be divided into two basic categories, Brown Materials such as leaves, hay, straw and paper, and Green materials such as grass clippings, fresh manure, vegetable trimmings and most green plant cuttings.

The main job of browns in a compost pile is to be food sources for all of the lovely soil-dwelling organisms that will work with the microbes to break down the contents of your compost pile . Brown items include dry leaves, straw or hey, eggshells, wood, pine needles, sawdust etc. Carbon: Nitrogen Ratio The C:N ratio can be determined easily when you know the C and N values and weight of the product you are Compost (/ ˈ k ɒ m p ɒ s t / or / ˈ k ɒ m p oʊ s t /) is organic matter that has been broken down into simpler organic or inorganic matter in a process called composting.
