Soil tillage methods have complex effects on the physical, chemical and biological properties of the soil with the influence on the crop. In the paper it was proposed to study the effect that agricultural works for the preparation of the germination bed have on the work of sowing wheat or the degree of sunrise. The studies started in the southwestern part of Olt County, on an area of 4.5 hectares divided into plots of 0.5 hectares. Germination bed preparation works were carried out on each plot as follows: conventional works for autumn sowing, land covered with mowed vegetable waste (TAV), reduced work using heavy disc harrows on land covered with plant debris (LDG), work with harrow with vertical rotors. (LGR). After the execution of the works for each plot, the soil moisture, the degree of crushing, the degree of compaction, the uniformity of the incorporation depth of the seeds were determined. The study will be continued by tracking the crop throughout the growing season, including crop production.
