Sažetak
Aimed at determining the optimal tillage method for the region, penetration resistance measurements were carried out on a Stagnic Luvisol in central Croatia. 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. The 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 till 50 cm) 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 30 cm. Soil resistance to penetration recorded in the winter period was expressly low, one might say it was practically non-existent. The overall lowest values of soil resistance to penetration throughout the investigation period were recorded in treatments with very deep ploughing and subsoiling or ploughing across the slope, while the highest penetration resistance was determined in the no-tillage treatment, as a consequence of the tillage method applied in this treatment.
