The different organic agriculture movements point out that agriculture considerably reduces the need for external inputs by not using chemical fertilizers, pesticides or other synthetic products, instead allowing the powerful laws of nature to increase both yields and crop resistance.
▶ One of the currents of thought of the organic agriculture movements considers that vermiculture is one of the activities that reduces the aforementioned needs, since it is a biotechnology that uses a domesticated species of worm as a working tool, recycles all kinds of organic matter obtaining as a result of this work humus, meat and worm meal.
For example, the general biology of the earthworm is a biologically simple organism, being water its main constituent (80 to 90%) of its total weight. It has different colors varying from pale, pink, black, brown and intense red with yellowish stripes between the segments, its shape is cylindrical with quadrangular sections, the size varies according to the species from 5 to 30 cm long and its diameter ranges from 5 to 25 mm the number of segment is according to the species, varying from 80 to 175 rings.
In terms of habitat and feeding, earthworms belong to the soil macrofauna, with a wide distribution in the world and with more than 7,000 identified species, all terrestrial species feed on organic matter decomposed on the surface, but they also use organic substances..
According to the food resources they exploit and the environmental conditions in which they live, they can be classified as detritivores, those that eat on plant mulch or animal manure in the surface horizons of the soil rich in organic matter.
I must say that being the body wall of red pigments and the geophagous, those that eat large amounts of soil with organic matter, usually pale colors, earthworms prefer moist sites, do not tolerate drought and frost, are more numerous in cool soils.
