At the present moment approximately 9 million tones of animal manure are accumulated in the Republic of Moldova every year. Due to lack of financial sources livestock waste can't be transported in the field, they are accumulated on small areas for storage, polluting the soil, groundwater and the air. The animal droppings at the same time contain various pathogenic agents, which serve as a source of infection for people, animals and plants diseases. The livestock waste processing with the California's red earthworms permits to diminish their quantity with 2 times, to increase the NPK concentration and diminish the doses of incorporation of the obtained vermicompost. The obtained experimental dates demonstrate that the processing of various types of animal manure with the aid of California's earthworms in the situation of the Republic of Moldova is related to significant losses of nitrogen and carbon. By the chemical composition of the vermicompost, obtained from different species of animals it is a little different from the properly fermented animal manure. Therefore, the doses of incorporation of the vermicompost for various crops will be very close compared with traditional manure. The existent recommendations for application of the vermicompost in the countries with advanced agriculture can't be used in the situation of the Republic of Moldova. The content of NPK in the vermicompost from our country is 8 – 10 times lower. In order to obtain a concentrated product (humus, biohumus, vermicompost) it is necessary to use in the process of waste processing with earthworms other additions too such as phosphorites flour (or apatites), bone meal, ash, blood meal, other slaughterhouse waste or food waste.
