Store bought vs home grown compost

Asked January 26, 2020, 6:15 PM EST

My home composter gets all the kitchen scraps from a lot of different sources, coffee grounds, fruits, veggies, etc. (no meat!) The compost you buy in a store is often turkey poop and bark. Is compost any better if it comes from a variety of sources?

Hello
The greater variety of organic material will provide a larger variety of nutrients and decayed material for microorganisms and your plants to feed on. I didn't find any specific studies that may show the difference in results from various compost types. Here is a nice composting resource from Virginia extension: https://www.pubs.ext.vt.edu/content/dam/pubs_ext_vt_edu/HORT/HORT-49/HORT-49-PDF.pdf
