Abstract

This experiment aims to study the food preference of earthworms. It was designed to see the effect of the presence of organic matter in relation to food preference. Bins were filled with both soil with organic matter and soil without organic matter in the same container. The organic matter consisted of newspaper clippings and grass clippings. Red wigglers (Eisenia foetida) were placed in the center and observed 48 hours later. Their preference was determined by the side of the bin where they were found. Repeated tests along with ph and nitrogen testing have provided a view into the behavior of earthworm food preference.
