Sažetak
Grain yields of field crops in the mountain region of Croatia are considerably lower than in lowland area, mainly as affected by soil and climatic limitations. Shortage of plant available phosphorus (P) and soil acidity have been found as main nutritional problems in this area. Aim of this study was to evaluate ameliorative P fertilization influences on nutritional status of soil situating in Lika region.The field experiment with increased rates of P fertilization was conducted on the acid soil with very low phosphorus level. Four rates of ameliorative P fertilization were applied in form of monoammonium phosphate (MAP: 12% N + 52% P2O5) as follows (kg P2O5 ha-1): a) control, b) a + 500 , c) a + 1000, d) a + 1500 and f) a + 2000. The standard fertilization included in total 134 N + 125 P2O5 + 83 K2O kg ha-1. Ameliorative fertilization with P fertilizer resulted by positive (increases of mobile fraction of P up to more than 4-fold, and AL-soluble P up to 6-fold) and negative (hydrolitical acidity increases up to 2.05 cmol kg-1) effects in soil. It is important that mobile fraction of harmful elements, especially Cd, were in all applied treatment at the control level. For alleviation of such negative effects we recommend a combination of ameliorative fertilization with liming.
