The article reflects the role of implementing soil fertility regeneration technology and enhancing the productivity of organic crops by using organic fertilizers obtained by using bioconversion of organic waste by worm’s cultivation that is geared towards the development of organic agriculture. Soil is the main natural wealth of the Republic of Moldova and requires special attention to carryng out agricultural work, considering the composition and particularities of soil, including humus and nutrient value. Therefore, measures are needed to improve soil fertility. The essence of the research was to highlight the role of worm's compost in the improvement of soil quality. To this end, in ETS „Maximovca” was organized an experiment that included three groupes (two – experimental, to fund worm's compost and one – control, the natural background). Observations of soil fertility were conducted in the third year of the influence to the worm's compost. The soil samples were collected by usual methods. As a result of the analyzes, in the soils in the worm's compost lots, the value of the organic matter, exceeded the value of the control lots by 18.7% - 39.5% and of the humus by 15.2% - 24.2%. Therefore, the worm's compost incorporated in dose of 3-4 tonnes/ha over three years improved soil fertility.
