This study was carried out to determine the effects of grazing on soil parameters in the meadow ecosystems in the alluvial delta plain of Samsun-Turkey. Five 5×5 m exclosures were established in the homogeneous stands in terms of habitat conditions and floristic composition in the study area during 2000-2003. The top of soil was firstly removed and then soil samples were taken from inside and outside of exclosures at a depth of 20 cm in each month for a year. Soil organic matter, pH, nitrogen, phosphorus, potassium, CaCO3 and total salinity were measured by standard methods. In general, CaCO3 and total salinity exhibited statistically significant differences between the grazed and ungrazed parts.
