abstract:
The aim of the research was assessment of sewage sludge fertilization effect on sulphur content in maize grown in soil of diversified texture. The research was conducted under conditions of a pot experiment. Fertilization with sewage sludge and mixtures of sludge and peat had a more advantageous effect on maize yields than mineral salt treatment. The amount of sulphur in maize biomass fertilized with sewage sludge increased significantly in comparison with this element con-centration determined in maize fertilized with farmyard manure. Mixtures of sewage sludge with peat affected the plant biomass yield slightly more favourably than the applied sewage sludge with-out admixtures, but they were less advantageous to the plant sulphur concentrations. Conducted experiments confirmed a potential of increasing the content of sulphate sulphur in soil following the application of sewage sludge. The effect of fertilization using sewage sludge mixtures with peat on sulphate sulphur concentrations in soils was comparable to the results obtained after farmyard ma-nure application.
