Sažetak
Aimed at determining the optimal tillage method for the region, four-year penetration resistance measurements, among others, were carried out on stagnic podzouvisols of the trial field near Daruvar in central Croatia. The trial included the following treatments: Standard plot, Conventional ploughing up/down the slope, No-tillage, Conventional ploughing across the slope, Very deep ploughing across the slope (50 cm) and Subsoiling to the depth of 60 cm + conventional ploughing across the slope. Crops were sown in the following crop sequence: 1994/95 - maize, 1995/96 - soybean, 1996/97 - winter wheat, and 1997/98 oil rape. Measurements of soil resistance to penetration to the depth of 50 cm in four repetition, as the principal parameter of soil compaction, were carried out continuously parallel to the plant cover growth and application of appropriate agricultural practices using The Bush Soil Recording Penetrometer. At the same time, samples were taken of the soil while in disrupted state in order to determine its moisture. The four-year investigations point to the conclusion that the soil resistance to penetration is predominantly influenced by the effective state of the plant cover development, actual soil moisture and the tillage method applied. The lowest penetration resistance results in all trial treatments were recorded in first measurements, immediately after the application of tilling practices. In treatments involving deep practices (very deep ploughing and subsoiling) penetration resistance values were constant to the measurement depth whereas an increase was recorded in penetration resistance below the ploughing depth in treatments with conventional ploughing to the depth of 25-30 cm.
