The trial was carried out at the experimental fields of Maize Research Institute Zemun Polje Krnjesevci near Belgrade, Serbia on meadows chernozem soil type. The following ameliorative and conventional tillage systems were included in investigations: 1) Ameliorative tillage system - (ATS) - includes new types of machines for field systematization-scrapers (USM 5) in autumn, drainage plow on the depth 60-80 cm, and subsoil with heavy vibratory subsoiler VR 5, on 30-35 cm depth. After basic tillage we prepared soil for seeding with preparation by disking and harrowing; 2) Control variant - conventional tillage without ameliorative measures. During 2008, previous crops were maize and sunflower after that ameliorative measures. Second crop in 2009/10 were winter wheat. The following soil properties were studied: bulk density, total porosity, moisture weight and volume percent, and total water content in different layers in cubic meter, in tillering and heading stage of winter wheat on the different depth 0-10, 10-10, 20-30. Ameliorative tillage systems had subsequently effects for all investigated soil properties in this heavy soil type compared with control.
