They move around, creating air holes in your compost pile. The bacteria that breaks down your scraps into compost thrives when it is moved, and when it has availability to air. Their feces also help provide richer compost for gardening.
Bottoms, sides, and tops are places where holes are put in the compost bin. The holes must be big enough to facilitate air flow but small enough to discourage foraging pests and inclement weather. There needs to be drainage from the bottom, release from the top, and ventilation through the sides.
That it improves fertility and moisture are reasons why compost is important in keeping soil healthy. Compost is fresh-smelling and nutrient-rich so it improves soil structure and texture by aiding air pore creation as well as moisture and nutrient drainage and retention.
Drill aeration holes along the side and into the lid and drainage holes in the bottom, layer alternate piles of carbon- and nitrogen-rich materials from household scraps and yard debris, and monitor air, heat, light, and moisture levels is a way to build a compost bin from an old trash can. The lid needs to be on when the compost pile is not being monitored or turned. It will be important to keep a hose for irrigation (to the consistency of a wrung-out sponge), a rake (or something to turn layers over), and a thermostat (to check heat and light levels).
The heat stays mostly inside the compost, that's why it is important to turn the compost inside out regularly, so that every part of the compost gets sterilized from bad germs. In open air compost heaps, the heat will evaporate as vapor, especially visible in cold weather. That water loss needs to be compensated. There is probably not much residual heat at the surface of a compost bin. Heat usually goes up, but in that case, the heat is not in air or water, but in the mass of the compost itself, so it radiates in all directions. A small container such as a compost bin would see most of the heat exchanged from every side.
Convenient location, durable choices, proper procedures, and sanitation schedules are ways to sustain a compost bin. A compost bin needs to be located away from heavy traffic and strong heat, light, and winds. It requires the incorporation of strong metal, plastic or wood interspersed with air holes or mesh as well as regular sanitation inspections.
Crystals do not have air holes.
You can put them in your compost.
the steam from the compost has air born partials that if you have a weak immune system can indeed make you sick.
oxygen is
No, compost is bulky and will have air-spaces. So less compost can be packed into the litre container. Water is a liquid and will fill the container completely, and will be heavier.
The worms do make holes but it is to but oxygen in to decompose the soil and therefore making compost, they also drag leafs into the compost to eat and to make more soil well theirs your answer :).
