Earthworms enhance the mineralization rate and efficiency of organic fertilizers and also increase crop yield when inoculated in a field. This increased efficiency may lead to less fertilizer input, thus increasing the economic and ecological sustainability of organic and non-organic farming. Earthworms contained in a plot could also facilitate the processing rate of unprocessed organic fertilizer. In order to better harness the advantage of soil inoculation with earthworms, they need to be maintained at high population levels. The objective of this study is to find a low -cost techinque to maintain high population of earthworm in the field. The efficiency and economic sustainability of each method will be evaluated.
