How Long Does It Take For A Corn Cob To Decompose
It takes about 5 to 6 months for a corn cob to decompose depending upon the soil and climatic conditions. Corn cobs are so large and they decompose slowly. Corn cob may take up to two months to decompose completely while using some active compost techniques.
If using the normal cold composting process, the corncobs decompose, about in three months, depending on several factors. If you are dropping several corn cobs in a smaller, cooler compost pile, one with not much track record, these cobs are going to be sitting there for a very long time before they begin decomposing. Yes, you can compost corn cobs, but it really takes much longer to break down if you let them dry before adding them to a bin or pile. Cutting the corn cob stalks means the corn cob stalks do not take up huge swaths of space all over the compost pile.
Often, people will even save some of the corn cob stalks separately to use later on, once they have seen their compost piles getting overcrowded. There is not really an answer for that, since they both could easily benefit from having some corn cob stalks added, however, larger, open compost bins do not have to shred cobs. While not applicable for corn cores, adding corn cobs to your compost is great for providing extra structure too.
You can either use an open compost pile, or you can create a frame that keeps things closed down for you to compost the corn kernels and the cobs, along with the rest of the parts from your corn plants. The cobs, stalks, leaves, and even the husks from a corn plant can all be used in your compost pile. Corn husks are extremely helpful for composting, and they can also serve as mulch for plants. It is true you will not always get fresh corn husks, but you can compost even brown ones.
Composting the leaves, the husks, even corn stalks is a better choice, too. You can also use the other parts that are left over from corn plants that are planted with the corn on your compost pile, like stalks, leaves, and even the silks from the corn. Generally, all parts of corn can be composted, including the corncob, the shell, and the stalk. The good news is the cob is not the only part of corn that is compostable.
It is important to note that the maize plants are not suited to be directly composted as they contain toxic substances. Corn kernels themselves are useful in the decomposition process, as they contain small pockets of air which, if reacting with nitrogen from your pile, may help decomposition in the beginning. First, since corn kernels require longer time to compost than the average, they produce pockets of heat and air within the compost pile that may help accelerate the composting process of surrounding organic materials.
Although it takes more time than composting corn husks to compost corn cobs, cobs have another purpose before they even decompose into usable compost. By learning more about the best ways to compost corn husks and cobs, then following the steps I have laid out in this guide, you will be able to convert your corncob scraps into luscious compost. When done properly, not only will you be able to add the corn husks and cobs to your compost, you will be able to watch them quickly decompose.
| Types | Time to decompose |
| Corn stalks | 18–360 days |
| By adding precious nutrients | 2-3 minutes |
Dried husks are a little more difficult, and they need to get a little bit of moisture from the rest of the composting materials in order to start breaking down. It is important to know that corn husks are bad for soil as they remove nutrients from soil. Corn husks are environmentally friendly and also have other uses, until eventually decompose and become a beneficial part of soil. While corn husks and stalks can be composted, they are not easy to decompose, with corn stalks taking 180-360 days to decompose in the compost pile.
Even when the corn kernels are still on the cob, these themselves decompose rapidly, though you may need to chop up the cob to aid its breakdown. Corn kernels have plenty of moisture in them already, which will get absorbed and crushed into your compost pile, leaving just the dry, hard parts — those should also break down quickly. You will want to chop up your corn in smaller pieces so it can decompose faster. You could choose to leave the scraps of corn kernels intact, but it would be hard to mix it in with your existing compost materials and would slow the decomposition process.
In addition to adding air pockets to your compost pile, using the whole corn cobs may speed up the decomposition process. Woody materials such as twigs and branches are awesome, but corn cobs are also fantastic, keeping gaps open at the center of the pile, ensuring your compost remains airy. To maintain the balance in your bin, you will want to be adding more carbon than nitrogen, and the good news is that corn cobs are high in carbon, and they will help to keep the compost balanced. If your bin is composting at high temperatures, with a good balance of carbon and nitrogen, then working to its fullest capacity, cobs will go away a lot faster than they would in a cooler, slower-activating bin.

As with all organic materials, the way in which you compost corn cobs will also impact how long it takes for them to decompose, since different processes yield finished compost in varying amounts of time. In addition to adding precious nutrients, you can expect that properly prepared corn cobs and stalks can decompose within 2 – 3 months on your compost pile. Corn may take longer to break down than average, but letting it compost slowly in your yard is far better than shipping it to the landfill.
You can cut the stalks and leaves from your corn and let them sit on top of your soil to introduce nutrients back into your soil when you harvest. For corn shell compost, you can either use the green shells that are removed before eating fresh corn, or brown shells that are left whole around corn ears for seed collection or feeding livestock.
Many people just throw away corn scraps because they think that corncobs cannot be composted. It is time to learn whether corn cobs can be composted, how they should be treated, when eliminating food waste, to create healthy compost, using the formula for composting ingredients in proportion, since there is a lot of cob-corn consumed each day. Decomposing corn cobs using compost bins is a green idea by any measure, and better carbon dioxide production vs. methane production, since the carbon will be decomposing anyway.

How long does it take a corn stalk to decompose?
Corn cobs and stalks, when properly prepared, will decompose in your compost pile in as little as two to three months, in addition to delivering vital nutrients. If you get it incorrectly, though, you can count on corn cobs protruding from your compost heap or tumbler over the upcoming year or two.
Do corn husks break down in compost?
In a compost pile, corn husks can decompose slowly or quickly. If given enough time, most organic matter decomposes into compost. Corn husks and other yard waste can be piled in a corner to form a cold, slow compost pile that could be usable in one or two years.
Should corn cobs be composted?
They can, yes! Corn cobs take longer to compost than corn husks, but even before they break down into suitable compost, the cobs have another use. Corn cobs that aren’t broken up create air spaces in a compost pile.
