Organic material in the soil is essentially derived from residual plant and animal material, synthesized by microbes and decomposed under the influence of temperature, moisture and ambient soil conditions. There are two groups of factor that influenced inherent organic matter content: natural factors (climate, soil parent material, land cover and /or vegetation and topography), and human induced factors (land use, management and degradation). During last decades great changes were occurred also in Slovak agriculture, which could influence also level of soil organic matter (SOM). To find the trend in development of SOM in Slovak agricultural soils is possible by Soil monitoring. Throughout ten years of Soil monitoring some trends in development of SOM was found. For the period of 90-ties on all arable soil groups slight decrease of organic carbon contents was recovered, which can be connected with complex changes in Slovak agriculture. On the beginning of new millennium minor increasing of SOM was detected. Small increase of SOM can be connected with increased of farmyard manure on arable land. On grassland during monitoring period, negligible, however gradually increasing of soil organic carbon was found.
