Analytical procedures for the determination of selected speciation forms of sulphur have been proposed. The method for conversion of sulphur sols into homogeneous solutions sols allowing simultaneous determination of sulphur either in model solutions or in sols environmental samples has been described. The methods for determination of sulphur sols, elemental sulphur, soluble and insoluble sulphides, sulphates and total sulphur have been optimized. Selected speciation forms of sulphur were determined in the same samples of water and bottom sediments from the eutrophic lakes Lipno and Kiekrz, lying close to Poznan. The speciation analysis proposed is based on the catalytic, chromatographic, ion-selective methods and absorption spectrometry. The concentrations of the speciation forms of sulphur determined ranged from micrograms to milligrams per litre.

A three-year field experiment was conducted in Byszwałd near Lubawa in 2000-2002. The aim of this study has been to determine the influence of increasing rates of sulphur on the dynamics of available phosphorus in soil at two horizons: 0-40 and 40-80 cm. The trial was set up on acid brown soil of the granulometric composition of heavy loamy sand. The initial soil had the following properties: pH(KCl) = 5.30, mineral nitrogen 24.0, sulphate sulphur 4.10, available phosphorus 34.5 and potassium 110.0 mg kg-1 of soil. Three levels of sulphur fertilization were applied: 40, 80 and 120 kg⋅ha-1 in the sulphate form (S-SO4) and as elementary sulphur (S-S0). During the whole duration of the field trials, the results demonstrating the effect of fertilization with different forms and rates of sulphur on the content and transfer of available phosphorus in soil were inconsistent. Only the dose of 120 kg⋅ha-1 S-SO4 caused a significant increase in the concentration of available sulphur in soil in the 0-40 and 40-80 cm layers. All the rates of elementary sulphur as well as 40 and 80 kg⋅ha-1 sulphate sulphur caused little less but an increasing tendency in the content of phosphorus in soil. The effect of elementary sulphur became apparent as late as the third year of the trials. The effect of the doses of 40 and 80 kg⋅ha-1 of sulphur on properties of soil depended on the form of sulphur, duration of the experiment.

The study assessed the effect of various forms of sulphur (Na2S2O3, elemental S and Na2SO4) and nitrogen (UAN-30, NH4NO3) on calcium and magnesium content and uptake in spring wheat and cocksfoot. A two-year pot experiment was conducted on soil material of clayey silt granulometric composition. Before the experiment, the soil was characterized by slight acidity and low content of assimilable forms of phosphorus, potassium, magnesium and sulphur. The results show that the experimental factors caused noticeable variation in the content and uptake of calcium and magnesium in spring wheat and cocksfoot. Among the sulphur fertilizers, the greatest increase in calcium and magnesium content and uptake was produced by application of sodium sulphate. The increase in calcium and magnesium uptake was more marked in the case of plants fertilized with nitrogen in the form of ammonium nitrate. The effect of nitrogen fertilization on the analyzed parameters also depended on the species of plant. Wheat grown in the series with ammonium nitrate was characterized by higher Ca and Mg content and uptake than plants fertilized with nitrogen in the form of liquid UAN 30. Calcium uptake by wheat fertilized with NH4NO3 was on average 15% higher for grain and 9% higher for straw compared to wheat fertilized with UAN 30. As for magnesium, the increase was 24.5% and 18%, respectively. Concerning cocksfoot, fertilization with UAN 30 had a greater affect on content and uptake of the analyzed nutrients than ammonium nitrate.
