define vermicompost and how it is different from compost
Answers
Answer:
The process by which the earthworms enrich the soil is called vermicompost. Vermicompost is easy than that of compost
Explanation:
Composting: Compost piles are typically hot as the aerobic breakdown of organic matter releases carbon dioxide and heat, resulting in piles than can top 150°F. This is good because the heat can kill the pathogens present in your compost input.
Vermicomposting: Composting with worms is a necessarily cooler process with temperatures ranging between 50-90°F. The downside to less heat is that vermicomposting will not kills any pathogens present in the food waste, manure, or whatever you’re feeding your worms.
One caveat here! Worms can move into a cooled compost pile, which is good. Conversely, hot composting can take place in worm bins that have been overfed….bad!
Microbial Populations
Composting: Since traditional compost piles can get hot, they are dominated by thermophilic (or “heat-loving”) microbes that can thrive in those temperatures.
Vermicomposting: Worm compost is dominated by mesophilic microbes that require more moderate temperatures.
Speed of Processing
Composting: It’s sloooooow. A hot compost pile can take 6-9 months to finish.
Vermicomposting: Much faster. A vermicompost bin can become “finished” and ready for harvesting in as little as 8-12 weeks.
Aeration
Composting: Again, the depth of compost piles necessitates that they be turned in order to ensure all input materials get processed. You can use rolled chicken wire or landscape cloth to create “chimneys” to help oxygenate the insides of a compost pile, but they will still require some amount of turning.
Vermicomposting: These magical worms actually do your turning for you! And because vermicomposting bins are relatively shallow, turning is not required, especially in continuous flow-through digesters!
Space Required
Composting: Because hot compost piles are deep, you typically don’t need that much space for a given volume of compost.
Vermicomposting: The epigeic earthworms used in vermicomposting do not burrow and will only work the top 6-12 inches of material, so available surface area, not depth is the limiting factor. You can get creative and stack your bins or devise a way to make the most out of your space, but as a general rule, vermicomposting does not lend itself to processing massive amounts of waste at one time.
Cost
Composting: Composting is cheap! Just find a surface you don’t mind using for composting and just start layering on your browns and greens. Nothing to it.
Vermicomposting: Vermicomposting isn’t expensive, but you do have to buy the worms and a bin unless you want to make one yourself. While this doesn’t necessarily cost anything, there is a requirement to protect your worms from extreme elements, which means going through the hassle of reserving space and the possible expense of heating or cooling your vermicomposting area.
