Composting organic waste produces nutrient-rich soil amendments, which are essential for expanding agriculture and managing trash sustainably. Earthworms improve the nutrient cycle and soil structure, which helps this process along. Important species that affect composting effectiveness include the Eudrilus eugeniae (African Nightcrawler) and Lumbricus terrestris (Common Earthworm). These species have different eating habits and environmental requirements. Despite their ecological significance, little is known about their precise feeding preferences and activity patterns in organic composting systems. The purpose of this research is to better understand how these earthworms behave in these kinds of settings by looking at their preferred substrates and how environmental elements like pH, moisture content, and temperature affect their eating patterns. The study also evaluates their efficiency as detritivores and how their activity affects the results of sustainable farming methods, improve waste management, and optimize composting procedures. After one (1) week of conducting this experiment, we could conclude that, Edrilus.eugeniae (African Nightcrawler) is the most effective in conducting the composting method. In conclusion, between two species (Eudrilus.eugeniae and Lumbricus terestris) that has been chosen, we recommend using Eudrilus eugeniae (African Nightcrawler) to conduct organic composting.
