Earthworm ecology

The establishment of earthworm communities. Their effects can be summarised as follows: Increase soil pH Increase decomposition rates Probably Increase humus formation rate Improve soil texture Enrich the soil Earthworms excrete surplus nitrogen in the form of ammonia, which is excreted into the intestine and then removed with the faeces during defecation. When the pH of soil becomes neutral pH 7 or alkali greater than 7 the growth of bacteria is favoured and these bacteria increase the rate of organic decomposition, producing a mull-type humus. In acidic soils, fungi are more dominant as decomposers, producing a mor-type humus.

Earthworms also increase mixing between soil layers. Worm casts are richer in minerals that are in forms more readily available to plants, such as salts of calcium, sodium, magnesium, potassium, phosphorus and molybdenum. In English pasture, lumbricid earthworms have been shown to produce 7 to 16 kg of casts per acre per year.

Conservation Land Management CLM is a quarterly magazine that is widely regarded as essential reading for all who are involved in land management for nature conservation, across the British Isles. CLM includes long-form articles, events listings, publication reviews, new product information and updates, reports of conferences and letters.

Exceptional customer service Get specialist help and advice. Includes papers on the influence of: earthworms on soil organic matter dynamics and microbial ecology; the use of earthworms in organic waste management; the importance of earthworms in the environment; the effects of earthworms on soils physical properties. The book presents an in-depth discussion of earthworm biogeography, diversity, taxonomy, and systematics; and it provides full coverage of earthworm feeding behaviour, food preferences, dietry requirements, and interactions between earthworms and microbial communities.

Information on the impacts of climate, human activities, soil properties, predation, disease and parasitism, and competition upon earthworm ecology is included.
