What is the effects of earthworm density on GHG emissions?

20 April 2020 1 879 Report

Why higher earthworm density increased CO2 but, decreased CH4 emissions during vermicomposting?

I guess it increases the penetration of O2 leading to CH4 aerobic oxidation and promoting aerobic organic matter respiration (increasing CO2).

How do we manage a massive biomass of earthworms containing high levels of toxic substances?

The initial materials for vermicompost are highly toxic (e.g., sewage sludge). However, earthworms (vermicomposting) stabilise this material, and the end product, vermicompost, is safe for...
