b) Structure and Aeration: Bacteria need oxygen hence air needs to diffuse through the heap to each piece of waste. The only way to get highly nutritious compost is by observing the right nitrogen and carbon proportions. When using compost as a substitute for fertilizer, it is important to know its carbon to nitrogen ratio, in other words, how much nitrogen it contains. help would be appreciated. It is a ratio of carbon to nitrogen. You add to slow compost systems gradually, a small bucket of food scraps and straw every day or so. Most compost books you read will say stick to a carbon/nitrogen ration of 25:1. A compost pile needs about a ratio of 30:1 carbon to nitrogen. All compost ingredients are groupable into either carbon-rich or nitrogen-dense categories. Usually you don’t turn it the first time UNTIL it reaches 65 degrees, so you turned it a little bit early. (24 parts carbon to 1 part nitrogen). We comfortably use shredded office paper Emma. When the ratio is higher than ideal (too much carbon), the pile will be dry and very slow to decompose; simply add nitrogen. A booster does sound good.

Here’s a photo from the Fork and Hoe Collective composting – the early morning light captured the compost steam beautifully. #4 – Divide the carbon totals by the nitrogen totals to get the C: N ratio 21.5/0.62= 34.7 parts of carbon to 1 part of nitrogen is the cumulative C: N ratio of your compost recipe. i have been trying hot composting but something doesnt feel rite. Well, according to the USDA, the ideal carbon to nitrogen rate for optimal microbial action in a compost pile is between 20:1 and 40:1, with 24:1 being the absolute sweet spot. To help compost be the best it can be you can add compost activators – their job is to inoculate the compost pile with their nutrients, giving it a serious BOOST. Taking ages to break down: Not enough nitrogen materials, add more rich materials (food scraps, manure, green lawn clippings) and turn the pile to add more air. A compost pile needs about a ratio of 30:1 carbon to nitrogen. Table 1 shows the estimated C:N ratio for some common brown materials. Carbon to Nitrogen ratio (C:N) is a ratio of the mass of . Give it a Grow 38,858 views. C/N Ratio. We turned it and now it hasn’t reached more than 35C. Of the many elements required for microbial decomposition, carbon and nitrogen are the most important.

Hot composting involves building a compost pile (in one go) which is at least one cubic metre in size, any less than this and it wont be able to generate the heat required to break down the organic matter and kill off pathogens (bad bugs) in the desired time frame. 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. There are 4 universal inputs: carbon, nitrogen, water and air. A carbon-to-nitrogen ratio (C/N ratio or C:N ratio) is a ratio of the mass of carbon to the mass of nitrogen in a substance. Still avoid glossy magazines. Suppose another specimen has 35 percent carbon and 5 percent nitrogen. No. Ideally, the estimated C:N ratio for composting is between 25:1 and 30:1 portions of carbon and nitrogen for a faster composting process. C/N Ratio. The carbon to nitrogen ratio (C: N) is a ratio of the weight of carbon and nitrogen in a substance. and how much booster would you recommend putting in there? Carbon materials (also called brown materials) also contain some nitrogen and nitrogen materials (also called green materials) also contain carbon. The ratio by volume should be 2 parts carbon to 1 part nitrogen. You need to turn the pile to make sure it ‘cooks’ evenly. It's best to have all of your materials on hand when you build the hot compost pile. A lot of "browns" (high carbon materials) are woody and do not break down into mush - they stay as pieces and create aeration pathways. Did it compost any faster - no the rate at 60C is the same. C:N impacts on compost use. And on top of that, it needs to be in the correct amounts. Divide the carbon total by the nitrogen total to get the C:N ratio. By continuing to use the site, you are agreeing to our use of cookies. Well, according to the USDA, the ideal carbon to nitrogen rate for optimal microbial action in a compost pile is between 20:1 and 40:1, with 24:1 being the absolute sweet spot. Nitrogen tends to heat the compost up and moves bacterial growth and reproduction into high gear. It is a virtuous circle the higher the temperature the faster they work and the more heat is released. I can’t recommend quantities as it depends on the other inputs you put in as well. Carbon ingredients is anything that’s dry and brown (think dead), such as straw, hay, brown leaves, shredded office paper, ripped/scrunched newspaper, cardboard – you get the idea.

If the C:N ratio is too low (excess nitrogen) you will end up with a stinky pile. However, you do not need the exact carbon: nitrogen ratio to make compost. Saw dust has very high C:N ration of 500:1. So, in general, you should have 4” layers of brown material alternating with 2” layers of … Carbon is also released as CO2. Yes, faster than anything! As in typical cold composting, a deep litter bed involves combining the right ratio of carbon and nitrogen rich materials. We're p, This error message is only visible to WordPress admins.

Add some hard particles (e.g wood chip) that will maintain aeration structure. Hi – our hot compost reached a high of 46C on day 3 then started cooling. 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. Carbon provides both an energy source and and the basic building block making up about 50 percent of the mass of microbial cells. Other indicators of this are slower decomposition speed, and much lower temperatures (which fungi prefer). As carbon gets converted to CO2 (and assuming minimal nitrogen losses) the C/N ratio decreases during the composting process, with the ratio of finished compost typically close to 10/1. (it will be used in the absence of any nitrogen for a simple reason not all food is used to reproduce and create new cells - some energy is need to respire (breath / live). This is because the bacteria responsible for the composting process require these two elements in those proportions to use as nutrients to construct their bodies as they grow, reproduce and multiply.
