A worldwide survey of earthworms in the humid tropics revealed that 51 exotics and native species are commonly found in tropical agroecosystems. On the basis of frequency records and climatic and edaphic ranges, 21 exotics and 27 native species have been . maylastfor years after earthworms havebeen removed from the sail. The joint presence of both 'compacting'and 'decompacting'species and organicresidues in tropical agroecosystems appears to be necessary to sustain physical soil fertility.

You can post the first one. Earthworms are important processors of soil organic matter (SOM) and nutrient turnover in terrestrial ecosystems. In agroecosystems, they are often seen as beneficial organisms to crop growth and are actively promoted by farmers and extension agents, yet their contribution to agroecosystem services is uncertain and depends largely on johnsonout.com by:

By B. Ortiz, C. Fragoso, Irène M'Boukou, B. Pashanasi, B.K. Senapati and A. Contreras. Abstract. An ethnological survey of knowledge of earthworms was carried out in four tropical countries (Mexico, Peru, India and Congo). A total of farmers from 20 localities were interviewed to clarify.
A synthesis of regional and worldwide patterns of natural and disturbed tropical earthworm communities The abovecase studies showthatwhennaturalforests andsavannasare con verted to agroecosystems, earthworm communities change in abundance, biomass, number of species, ecological categories and species composition.
therefore, been hypothesized that management options that stimulate the activities of these organismscould promote sustainable production in tropical agroecosystems (Swift, ; Myers et al., ).
Results from previous chapters suggest that the success of techniques of earthworm managementCited by: Several other species showed significant advantages in particular situations, and are likely to be useful under wider conditions of crop and soil management. Plants most affected were tropical trees (in Peru), tea in India, and #Panicum maximum$ grass, planted both in Australia and the Ivory Cost.
Most successful species tested so far for in-soil earthworm technology is P. corethrurus. A culture bed of 5 m 1 m 20 cm filled with a mixture of soil and partly composted saw- dust, adult P. corethrurus ( g fresh weight) produced worms (including immature) within 4 months .

Aug 01, · Earthworm Management in Tropical Agroecosystems The great increase in the number of articles dealing with earthworm ecology and their role in soil ecosystems over the past two decades is testimony to their importance to soil fertility and their utility in addressing fundamental questions in ecology.
In order to achieve these objectives, three studies were conducted using natural tropical soils (oxisols and hydromorphic soils) and tropical earthworms sampled in a small catchment basin located. Mar 03, · Earthworm populations were studied in three tropical agroecosystems of southern Mexico: improved maize with a Mucuna pruriens cover crop (MM), continuous conventional maize (CM) and pastures (P).
