The trick, of course, is to hit the composting “sweet spot” with a carbon-to-nitrogen ratio of about 30:1 for the initial feedstock blend. Are They Escaping? Decomposers that actively break down organic matter prefer a diet containing about 30 times the amount of carbon-rich material as nitrogen-rich material, or a C:N ratio of 30:1. #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. Stable soil organic matter has C:N of 12-15. The calculator is primarily intended for manure composting, however it can be used for other materials as well. Researchers report optimum values from 20 to 31. You can build excellent compost without using a calculator. For instance, one cubic yard of horse manure needs 150 gallons of of a loose material like dry leaves to achieve a C:N of 25:1. They found that the optimum range for speed was between 30:1 to 35:1. As a soil amendment before planting new beds, use 1-3 inches of compost dug or tilled into the soil. If you see incorrect data, would like to see an ingredient added, or have general questions, please feel free to e-mail me and let me know! Electrical Conductivity (EC) A measure of soluble salts High salts may injure plants. C means Carbon. The ideal C:N for composting is approximately 25-30:1. Electrical Conductivity (EC) A measure of soluble salts High salts may injure plants. Guide to Red Wiggler Composting Worms: Everything You Need to Know, Red Wigglers Vs Indian Blues: How to Tell the Difference, What Do Worms Eat? This Price to Earnings Ratio Calculator makes it easy to calculate the P/E rat carbon/nitrogen ratio [written as C:N] is used as a primary indicator of nutrient content. The second composting recipe could be correct, but it is probably not. You may hear the C:N ratio bandied about in discussions among avid composters. 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. Adding compost or other nutrients can help you find the right carbon-nitrogen ratios. If you wish to analyse and achieve 30:1 then there are online calculators to help. Therefore, compost piles are limited to plant material. Urban Worm Guide to Coconut Coir: How is It Used and Why? C:N Ratio: Ratio of carbon to nitrogen. C provides energy and microbial cell structure while N is linked to proteins, enzymes and other substances integral to cell growth and other biological functions. Phone: 509-773-4448. How To Calculate C:N Ratio for a Compost Pile. I’ve had frequent conversations about composting over the years. Pro Tip: Check out this handy list of the carbon-nitrogen ratio for various compost ingredients to get a general sense of how much of each to incorporate into your pile. As a result, the carbon content of a compost pile is continuously decreasing. So, for example, if your food waste includes high amounts of fruit waste, this can effect your calculated C:N. Composting and vermicomposting are aerobic processes. When organic matter decays, the carbon is dissipated more rapidly than the nitrogen, thus bringing down the carbon-nitrogen ratio. But there is a massive difference in bulk densities, especially with carbon-rich materials. On the other hand C: N ratio of the bodies of micro-organisms is not only more constant but much narrower between 4: 1 and 9:1. So for worm composting, we would like to see C:N at 50:1 or higher. This page provides a little more detail on the Carbon: Nitrogen ratio and lists a range of Greens and Browns in order of their Carbon content. CARBON-TO-NITROGEN RATIO To calculate the amounts of various materials to add to a compost pile with a C:N ratio of 30:1, you need to know the nitrogen and carbon con-tents of the individual ingredients. As the microbes consume the carbon material and the nitrogen is converted to the more plant-available forms of ammonium (NH4+) and nitrate (NO3-), the C:N will slowly drop over the course of several weeks, assuming no new additions of brown or green material. You need to fill in how many “parts” of each compost ingredient you are planning to add to your pile. In our experience, this level of detail is not needed to get achieve hot composting. I’d even seen somewhat complicated compost calculators on the internet. If they do, you can go and make your compost pile! It is a ratio of carbon to nitrogen. The results shown on the report page are calculated based on the ideal C:N Ratio (Carbon, Nitrogen Ratio) of 30:1 (30 parts carbon to 1 part nitrogen). C:N impacts on compost use. The fair proportion between these two components is called the carbon-to-nitrogen ratio or C:N ratio. Soil nutrient analysis laboratories or environmental testing laboratories can … Contact Us. Fax: 509-773-5991. I must stress that compost will still be produced if the C: N ratios of the bins are outside the recommended range. C provides energy and microbial cell structure while N is linked to proteins, enzymes and other substances integral to cell growth and other biological functions. For optimal performance, the beneficial microbes need the right ratio of carbon for vitality and nitrogen for protein generation.
