Sažetak
This paper presents results of one-year trials of compaction at two sites in Croatian region Slavonia and Baranya. Trial has been set up as CRBD with five soil tillage treatments: 1- conventional (mouldboard ploughing), 2- conservation (chisell), 3-conservation (diskharrowing), 4-conservation (paraplough), 5-direct drilling. At both sites in spring 2013 maize has been sown. Soil compaction and soil moisture has been observed twice per month, from mid-June to end-September 2013. Samples had been obtained from depths 5, 20 and 45 cm by Kopecky soil sampling cylinders (V = 100 cm3) on each soil tillage treatment. Statistical data analysis showed that at Čačinci site soil bulk density and soil moisture were in negative correlation. The strongest correlation has been obtained for disk-harrowing conservation tillage (r = -0.501), and weakest for conventional soil tillage (r = -0.016). At Magadenovac site soil bulk density and soil moisture were in positive correlation, which was unexpected. Correlation between compaction and depth had the strongest expression at Čačinci site, for conventional tillage (r = 0.628), and the weakest expression at Magadenovac site for paraplough (r = 0.216).
