| Popis: | The aim of this study is to determine the response of biomass yield and the content of K, Na, Ca and Mg in the eastern galega and soil under the influence of nitrogen in the form of (15NH4)2SO4. Three-year field experiment (2005–2007) was carried out on experimental plots belonging to the University of Natural Sciences - Humanities in Siedlce (52°17’N, 22°28’E). Nitrogen 15N was applied as ammonium sulphate at a dose of early spring 1.66 g N.m−2. In each year of the study were collected three cuts of eastern galega budding phase. Shown yield of dry weight of the test plant. The content of K, Na, Ca and Mg in the eastern galega and soil were determined by ICP-AES emission spectrometer with inductively coupled plasma. Subsequently, the uptake and marked weight ratios of macronutrients. Under the influence of nitrogen in the form of ammonium sulphate, dry matter yield of eastern galega (average of 3 years of research and 3 swaths) increased by 29.7%. Fertilisation with nitrogen contributed to the reduction of K content, increasing the content of Na, Ca, Mg, in a test plant and to increase the pick, all the elements analysed with the yield of biomass. Nitrogen fertilisation resulted in a reduction in the quantitative ratios K: (Ca + Mg), (K + Na) : (Ca + Mg), K: Ca, K : Mg and the total content of the analysed elements in the soil (average of the years). |
