OASIS VERITAS offers farmers and entrepreneurs, as well as large businesses, technology for the production of vermihumus by processing various organic wastes with a specialized breed of industrial line of earthworms Lumbricidae Eisenia colchidica optimum, bred by an experimental scientific laboratory under the direction of Dr. Kobaliia by crossing individuals from several spatially distant populations of Western Georgia: the endemic species of Colchis earthworms A. Pseudonematogena, amphibian species E. Colchidica, E. Tetraedra, N. dubiosus, H. patriarchalis of the Colchis lowland and compost worms E. foetida.
The Lumbricidae genera used in OASIS VERITAS vermitechnology combine species of dung, earthworms and many other worms. According to Dogel (1975), they belong to the rain family (Lumbricidae), the order of higher oligochaetes (Lumbricomorpha), the class of oligochaetes (Oligochaeta), the subphylum clitellata, the phylum annelidae (Annelida), the subkingdom metazoans, the animal kingdom.
Ecological features. According to their lifestyle, E. Colchidica, E. Tetraedra, N.dubiosus, H. patriarchalis are amphibious and inhabit moist soils near springs and streams, as well as swampy soils. However, Lumbricidae collected in the upper and lower mountain forest landscapes and other territories of Georgia are inferior in size to the worms collected in the Colchis lowland.
Lumbricidae Eisenia colchidica optimum has distinctive features of the shape and structure of their body.
The body is highly elongated and round in cross section. The anterior head section of the body is thicker, with strong muscles and darker in color; rear (caudal) – thinner and paler. The mouth is located at the head end of the body, and the anus is located at the tail end. The entire body of the earthworm is covered with epithelium, which contains glandular and cambial cells that secrete a transparent mucous film. This ensures the surface of the skin is smooth and makes it easier for the worm's body to glide when moving.
Lumbricidae are bisexual (hermaphrodites). However, reproduction requires mating of individuals (copulation). An earthworm reproduces only by laying eggs enclosed in special egg cocoons, which under optimal conditions are laid once every 5-7 days. When mating, individuals are attached with their ventral sides, their heads are turned towards each other, the girdle of one worm is located opposite the spermatheca of the other worm. The girdles of both worms secrete mucus, which covers them in the form of muffs. Sperm is released from the male openings, which enters the mucous membrane, from which it passes into the partner’s seminal receptacles. Then the worms disperse. Egg laying and fertilization occurs later, when sperm mature. In the girdle area, the worm forms a mucous membrane, from which a cocoon is formed, filled with a protein mass that serves to nourish the embryos. The muff slides through the head section, while fertilized cells enter it and the formation of the cocoon is completed.
The cocoon is an oval elastic capsule and resembles a lemon in shape. The color is light yellow in freshly laid ones and brown in ripening ones. Their diameter is from 2 to 4 mm. In each cocoon, depending on the conditions of the culture, from 2 to 20 eggs can develop. The hatched worms are 1 mm long, and by 6-7 days of age they grow to 4-7 mm. They are thin, like threads, and are distinguished by the presence of a clearly defined red spinal vessel. After emerging from the cocoon, they begin to feed.
The circulatory system of earthworms is closed and consists of 2 large (spinal and abdominal) blood vessels. In each body segment, two large blood vessels are connected by “blood” half-circles. The blood of ringworms is red due to the presence in the liquid part of the blood (blood plasma) of a substance very close to hemoglobin in the blood of vertebrates (“hemocruorin”).
There are no special respiratory organs: they breathe over the entire surface of the body. The thin cuticle and tenderness of the skin, the rich network of skin blood vessels provide the ability to absorb oxygen from the environment. The cuticle is well wetted by water, and oxygen first dissolves in water. This entails the need to keep the skin moist.
The remains of processed food are thrown out through the anus in the form of small granules - coprolites. Coprolites contain humic substances (humic acids and their salts - humates), which make these granules waterproof, water-intensive, resistant to mechanical stress and structure the soil, making it fertile and breathable. In addition, coprolites are centers of microbiological activity of a wide range of soil flora, and the digestive tube of worms is a source of constant replenishment of soil microflora with fresh generations of microbes - the main consumers (destroyers) of dead plant animal tissues and their decomposition in the soil into carbon dioxide and water.
According to some sources, the lifespan of Lumbricidae reaches from 4 to 16 years.
Our experience shows that cultivated worms do not get sick and are not subject to epidemics. They can die only due to non-compliance with their breeding technology.
The artificially bred species Lumbricidae Eisenia colchidica optimum is reared indoors year-round.
Their main feature is that they are designed for accelerated and higher-quality processing of organic waste from agriculture and industry (animal manure, bird droppings, plant residues, sewage sludge from treatment facilities, waste from food processing plants) into vermicompost - the basis of HUMUS BIOCOMPLEX OASIS, which is an organic fertilizer, a soil conditioner, a restorer of contaminated soils, and an improver of the microbiological condition and structure of the soil.
