The purpose of the research was the appreciation of the viermicompost quality. This material was obtained as a result of bioconversion of organical wastes (obtained from cattle) by worm cultivation, using wormculture (expecially the Red Hybrid of California). The bioconversion procces of organic wastes is implemented in the Experimental Section of the Scientifi c-Practical Institute of Biotechnologies in Zootechics and Veterinary Medicine. As a result of the studies to effect in several states, including the Republic of Moldova, it has been staded that the virmicompost has a positive infuence to infavorable climaterical conditions and to frecuent phitotechnical malgnis. In the agricultural production obtained as a result of cultivating on viermicompost. As a result of the research it has deen stated that the quantity of the C vitamin in some of the vegetables has increased by 1,5 – 9,4 timis. Whar s more the virmicompost has infl uenced positively the guality of the alfalfa, maize and sugar fodder, in which the azoth compounds guantity has diminished by 1,32 – 2,66; 3,47 – 3,76 and 1,10 – 1,14 times, in comparison with culteris cultiva ted with the help of mineral fertilizer. So, the agricultural and ecological importance of the viermicompost consists in improving the guality of agricultural production.
