I have always buried the food in my worm bins so that the microbes in the bin would start to decompose the food as quickly as possible. I decided to do not bury the kitchen scraps in three of my bins and document the results. Each bin is configured differently. I added equal amounts of scraps to each bin
Bin 1: A 5 tray Gusanito Worm bin with a mixture of Red Wigglers and African Nightcrawlers. The bedding is peat.

Bin 2: A 37 gallon bin with European Nightcrawlers. The bedding is peat and manure.

Bin 3: An 18 gallon bin with Red Wigglers. The bedding is shredded newspaper.

Bin 4: I buried the scraps in an 18 gallon bin with Red Wigglers. The bedding is peat and manure bedding.
My goal is to compare how quickly the scraps are consumed on top of the bedding compared to the buried scraps.
