Earthworms - Information
about the Master soil builders
Invertebrates (boneless) tube like
animals that can be found nearly all over the world. There are more than 3000 species of worms on our planet.
.Their bodies consist of up to 160 segments. The segments carry several pairs of bristles that are
used for movement and to resist predator’s attempts to pull them out of their
These bristles can work so effectively that worm bodies can snap into
2 pieces when predators attempt to pull them out of the earth.
The worms vary greatly in sizes.
Large compost worm - Eisenia Fetida
Earthworms are good for the soil
The Guiness book of records claimed that the largest worm ever recorded
measured 6.7 meters / 22 feet when naturally extended and had a diameter of 2cm
/ 0.8 inches and was apparently found in South Africa.
The smallest worms on the other hand can only be
seen under a microscope.
The worms are very important for healthy and
fertile ground. They dig continuously through the different layers of soil,
swallow large amounts of dirt and decaying matter.
Their tunnels aerate the
soil, allow roots of plants to grow to deeper mineral richer parts of soil
and make it easier for water to penetrate the ground and feed the plants.
As they digest their food they enrich it with mineralsand nutrients.
Their poop is called worm castings and is infinitely
richer in nitrogen, phosphor, potassium, calcium and magnesium than the richest
of top soil.
are so many different kinds of worms
active around the world there are actually only a handful of different
species that can be used successfully to work as domesticated compost worms.
Eudrilius Eugeniae, Perionyx Excavatus, Eisenia
Hortensis known as European Night crawlers and Eisenia Fetida know as Red worms
or Red wigglers are the ones that are used and marketed by most Worm composting
Despite the fact that all these worm species are able to
recycle large volumes of organic waste, it is the latter
ones ie. “The European Night crawlers and the Red wigglers" that clearly dominate the
world of worm composting!
Studies in the USA
have shown that in some parts of the country worms can produce up to 875 kg of worm
castings a day on an area of 10000 m2.
