Název v původním jazyce

Barley response to the soil reserve of sulphur and ammonium sulphate in short-term experiments under controlled conditions of cultivation

Popis výsledku v původním jazyce

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) andextraction 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 rangeof 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.
