Soil is the main natural wealth of the Republic of Moldova and requires special attention to carrying out agricultural work, considering the composition and particularities of soil, including humus and nutrient value. Land use provides, first of all return losses of humus and nutrients used by plants. Therefore measures required to improve soil fertility. The essence of the research was to highlight the role of worm's compost improve the soil. To this end, in ETS "Maximovca" was organized an experiment that included three groups (two -experimental, to fund worm's compost and one -control the natural background). Observations on soil fertility have been conducted over three years. The soil samples were collected by usual methods determined values of organic matter and humus. As a result of analyzes it was found that the soils of worm's compost fund lots organic matter value surpassed that of the corresponding control group by 10,3% -22,0% and 11,4% -18,4% humus. Therefore, worm's compost incorporated in dose of 3-4 tonnes / ha over three years, improved soil fertility.
