This study deals about quantity of soil organic matter in natural ecosystems and arable land. Sampling places were located in Nitra, Komjatice, Močenok and Šaľa on soil types Eutric Fluvisols and Haplic Chernozems. There were four different ecosystems: agri-ecosystem (arable land), forest ecosystem, meadow ecosystem and anthropic soil included. The highest carbon content was in forest ecosystem, next less about 14% it was anthropic soil, less about 20% it was meadow ecosystem and with the lowest value (about 27%) it was arable land. The highest total nitrogen content was in anthropic soil, next lower value about 2% was in forest ecosystem, lower value about 31% it was in meadow ecosystem and with the lowest nitrogen content about 32% it was arable land. Soil organic matter balance in crop rotation is not influenced only by root crop share, for which farmyard manure is applied, but also maize share. Oil seed crops very importantly support higher content of total organic carbon, as well. Just variants with the highest share of oil crops and maize had the highest carbon content.
