Top soils from 36 different farmed fields were used in experiments aiming to determine the impact of gypsum treatment on initial growth and nutrient uptake by spring barley. Barley was grown on experimental soil with 3.3 ppm CaSO4.2 H2O for 21 days in a plant growth chamber under controlled conditions of cultivation. Soil without gypsum application served as control. Concentrations of nutrients (N, NO3-, P, S, K, Mg, Ca, Na, Fe, Mn, Zn, Cu, B and Mo) were determined in shoot biomass. The yield of barley shoot biomass was significantly higher (by 15% on average) and N utilisation was better after gypsum application. S concentration increased five times on average, whereas Ca concentration increased by 22%. Significant increases were measured for Mg, Mn and Cu levels. Insignificant differences were recorded for K, Na, Fe and Zn concentrations. The uptake of anions (P, B and Mo) was influenced significantly. P and Mo concentrations decreased on average by 28% and 31%, respectively. B concentration was higher by 10% on average.
