ABSTRACT
The application of organic wastes, particularly composted municipal refuse and sewage sludge, significantly influenced soil structure and related physical properties of soil. A field experiment was conducted in 2005 on Stagnic Gleysol soil where different organic amendments were applied, such as compost, pig manure and sewage sludges. The results were compared with mineral fertilizers and untreated control. The amounts of all fertilizers were determined to supply 110 kg N ha-1. The application of organic amendment, such as pig manure and sewage sludge, decreased the macroporosity of soil. These changes concerned the regular and irregular pores ranging 50-1000 μm in diameter. It was probably the result of a choking effect of particles leached from the sewage sludge and pig manure. Mineral fertilization, compost or sewage sludge did not influence the porosity of soil.
