Description
  • The objective of the paper was to determine an appropriate concentration of available sulphur in soil for the initial growth of plants. Two methods of soil extraction were used to acquire information on the S-soil reserve: water extraction (1:5, w/v) and extraction in 0,5 M ammonium acetate (KVK-UF). Index of nutrient efficiency (IE=Y/N where Y=yield and N=nutrient concentration in the plant) and boundry lines of the point field were used to evaluate the efficiency of barley nutrition with S. The efficient S-soil for the soil test H2O when the ICP analytical technique was used was in the range of 8-11 mg S/kg; 6-10 mg S/kg for sulphate detection on a SKALAR analyser. The efficient S-utilisation by barley plants for the KVK-UF soil test was in the range of 7-12 S/kg. The conversion of the KVK-UF S-test to the S-index by adding up (0,0167xCEC+9,1667) improved the closeness of the relationship between soil and plant.

  • Záměrem práce bylo indikovat vhodnou koncentraci dostupné síry v půdě pro počáteční růst rostlin. K informaci o zásobě síry v půdě byly použity dva půdní testy: extrakce vodou (1:5, w/v) a 0,5 M octanem amonným (půdní test KVK-UF). K posouzení efektivnosti výživy ječmene sírou byl použit koncept indexu účinnosti živivy (IE=Y/N, kde Y=výnos a N=koncentrace živiny v rostlině) a hraničních linií bodového pole. Pro půdní test H2O (1:5) byla indikována efektivní zásoba síry v půdě v rozmezí 8-11 mg S/kg přianalytické koncovce ICP a 6-10 mg S/kg při detekci síranů na analyzátoru SKALAR. Pro půdní test KVK-UF v oblasti 7-12 mg S/kg. Převod S-testu KVK-UF na index zásoby síry v půdě přídavkem proměnlivého podílu z hodnoty CEC k hodnotě S-půdního testu (0,0167xCEC+9,1667) zlepšil těsnost vztahu závislosti mezi půdou a rostlinou.
