Sažetak
The field experiment of increasing rates of phosphorus (P) and potassium (K) fertilization was conducted in spring of 2004 on acid (pH in KCl = 3.99) soil (a = ordinary fertilization, b = a+P1, c = a+P2, d = a+P3 , e = a+K1, f = a+K2, g = a+K3 , h = a+P2K2). The amounts either/or P2O5 and K2O were (kg/ha) 500, 1000 and 1500, for the step 1, 2 and 3, respectively. The triplephoshate (45% P2O5+1.2% S+0.06% Zn) and KCl (60% K2O) were used. The experiment was conducted in four replicates (basic plot 77 m2). In the 2005 – 2009 period residual effects of applied fertilization were tested and only ordinary fertilization was applied. Crop rotation in the 2004-2009 period was as follows: maize (2004) – soybean (2005) – maize (2006) – winter wheat (2007) – maize (2008) – maize (2009). K fertilization resulted by significant yield increases up to 6% (2004 and 2006), 18% (2005), 14% (2007), 5% (2008) and 13% (2009). However, application both P and K (kg/ha: 1000 P2O5+ 1000 K2O) was the most useful because of yield increases up to 12% (2004), 28% (2005), 8% (2006), 18% (2007), 7% (2008) and 14% (2009).
