Sažetak
The stationary field experiment was conducted in spring of 2004 on Pavlovac (Bjelovar- Bilogora County-Croatia) very acid soil (pH in 1n KCl = 3.80) by the application of NPK 10:30:20 fertilizer as follows (kg ha-1): a = 0 (the conventional fertilization) ; b = a + 416 ; c =1249 ; d = 2028 ; e = 2916 ; f = 3748. Differences of N amounts added by fertdolomite were equalized by CAN (calcium ammonium nitrate: 27% N). The experiment was conducted in four replicates and the basic plot size was 77 m2. Two replicates of the experiment was limed in autumn of 2007 by granulated fertdolomite (24.0 % CaO + 16.0 % MgO + 3.0 % N + 2.5 % P2O5 + 3.0 % K2O) in amount 10 t ha-1. Two subplots from each replicates were harvested in order to obtain four replicates of grain yield data for each treatment. In this study was shown survey grain yield of field crops grown in rotation for 5–year period 2008– 2012 (maize – maize – soybean – maize – winter wheat). Mean yields of the field crops in the experiment were as follows (t/ha): 11.64, 10.70 and 9.02 (maize 2008, 2009 and 2011, respectively), 3.57 (soybean 2010) and 7.59 (wheat 2012). Response to liming was depended on the growing season (year effect) and field crop. As affected by liming, yields of maize were significantly increased for 5% (2008 and 2009) and for 8% (2011). Also, yields of wheat were similar for unlimed and limed plots in 2012 (7.64 and 7.54 t/ha, respectively). However, soybean responded to liming in 2010 by yield increases for 18% (3.28 and 3.85 t/ha, respectively).
