The paper reviews the presence of weed seeds in the soil by using two methods, physical extraction and germination method. Soil sample, under maize field, were taken from three locations: Dragočaj, Hrvaćani I and Hrvaćani II, in the spring of 2010 and 2011 at a depth of 0-10, 10-20 and 20-30 cm. By physical extraction, on all three locations, it was determine 44 weed species and by germination method 13 weed species. The highest number of weeds, by both methods, was determine during 2011 on site Hrvaćani II, at the depth of 10-20 cm. By physical extraction it was determine 38438 seeds/square meter and by germination method 14688 plants/square meter. Method of physical extraction, for all ascertained weed species, has showed a higher efficiency in determining of weed content in the soil in relation to the germination method.
