Abstract:

The paper presents research on the copper content in grain of winter wheat and spring barley cultivated in 1986-2001, on grey-brown podzolic soils developed from loess (static fertilization experiment) underlying a field located in the Rzeszów Foothills (SE Poland). The experiment was set up by the random sub-block method, on a field under a static fertilization trial composed of a four-year crop rotation system and the NPK Mg or NPK Mg Ca fertilization system. The first variable was liming (A) and the second one consisted of different mineral fertilization variants (B). The basic level of fertilization (N1P1K1) was 80 kg N ha-1, 100 kg P2O5 ha-1 and 120 kg K2O ha-1 under spring barley and 90 kg N ha-1, 80 kg P2O5 ha-1, 100 kg K2O ha-1 under winter wheat. The crop rotation was the following: in 1986-1989 - potatoes, spring barley, fodder cabbage, winter wheat; in 1990-1993, 1994-1997, 1997-2001 - potatoes, spring barley, fodder sunflower, winter wheat. Mineral fertilization included NPK fertilization with constant Mg fertilization, and differentiated NPK fertilization with constant Mg and Ca (liming) fertilization. Liming was performed in 1985, 1989, 1993 and in 1997 (4 t ha-1 CaO). The experiment included 14 fertilization variants with 4 replications. The copper content in plants was determined by FAAS after mineralization of plant samples in a mixture of HNO3:HClO4:H2SO4 in the 20:5:1 ratio. Liming decreased the copper content in spring barley grain but had no statistically significant effect on the copper content in winter wheat grain. Mineral fertilization did influence the copper content winter wheat grain, but decreased it grain obtained from the plot with lower P fertilization together with NK fertilizer. However the interaction (liming x NPK fertilization) did not influence the copper content in cereal grain.
