The trial was carried out at the experimental field Krnjesevci of Maize Research Institute Zemun Polje, Belgrade - Zemun (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 systematisation-scrapers (USM 5) in autumn, drainage plow on the depth 60-80 cm, and subsoiling 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) Conventional tillage (CT) - in this case includes ploughing to the depth of 30-35 cm + presowing preparation by disking and harrowing was control. 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 two period of time after first and after second interrow cultivation in maize on different depth: 0-10, 10-20, 20-30. Ameliorative tillage systems have better effect for all investigated soil properties on this heavy soil type compared with control with classical tillage system.
