This book explains the role of the earthworm in biodegradable solid waste management systems, from the simple Home Ecology Box to complex facilities for Annelidic consumption of municipal refuse. It will also look at the potential of earthworms as protein source for pets, livestock and even human beings.1/5(1). Earthworms; their ecology and relationships with soils and land use [] Lee, K.E. Earthworms increase porosity by two mechanisms: (1) by creating permanent burrows, and (2) by improving soil aggregation. Aggregation is improved by the mixing of soil and organic matter in the earthworms' guts. These highly stable aggregates are deposited by some earthworms in their burrows, and by others at the surface of the soil.

The use of earthworms in organic waste management: the life cycles and productivity of Eisenia fetida (Sav.), Eudrilus eugeniae (Kinberg), Perionyx excavatus (Michaelsen) and Dendrobaena veneta (Rosa), and their potential in processing animal and plant wastes, from sewage, agricultural, domestic, urban and industrial sources are summarized. The Cited by: A survey of portion of the wheatbelt in showed that earthworms are widespread, but their occurrence is related to land use. Earthworms are present more frequently in pasture soils than culti- vated ones (Abbott and Parker, ), which may result from the higher quantity and quality of organic matter in pasture soils than those cultivated Cited by:   Earthworms find in soil the energy, nutrient resources, water and buffered climatic conditions that they need. According to the food resource they exploit and the general environmental conditions, earthworms can be grouped into different functional categories which differ essentially in morphology, size, pigmentation, distribution in the soil profile, ability to dig galleries and produce Cited by: Earthworms, which belong to the order Oligochaeta, comprise roughly 3, species grouped into five families. Earthworms have been called ‘ecosystem engineers’; much like human engineers, they change the structure of their environments. Earthworms are very versatile and are found in nearly all.

Earthworms with the most food gained weight faster than those with little or no supplementary food. The latter also failed to become reproductively mature. Earthworms lost weight on a nitrogenpoor diet, but this was not rectified by supplementing such food with inorganic nitrogen added to Cited by: During sexual intercourse among earthworms, both sets of sex organs are used by both worms. If all goes well, the eggs of both of the mates become fertilized. You can imagine this is a highly efficient way of ensuring the survival of the species. Vermicomposters, people who raise worms and other organisms to compost, report that their earthworm.   1. Introduction. It is well known that earthworms play an important role in the soil macrofauna biomass. They are extremely important in soil formation, principally by consuming organic matter, fragmenting it, and mixing it intimately with soil mineral particles to form water-stable aggregates [].In particular, the bioaccumulation ability of earthworms is essential for a bio-monitoring Cited by: Lee, Keneth E.
