Abstract (en)

Soil organic carbon is one of the few indicators that characterize soil quality. Nowadays soil organic carbon status is low due to unbalanced fertilization, intensive pesticide use, non-use of organic fertilizer, straw removal, low plant diversity in crop rotations. Soil organic carbon balance can be maintained through sustainable agricultural systems, enriching the soil with organic manure, including catch crops to crop rotation. The aim of the study was to determine the organic carbon content in different soil fractions under different fertilization systems. It was found the highest organic carbon content (14.22 g kg-1) in <2 mm fraction compared with control. Generally soil organic content established in organic - mineral fertilization system in both fractions- 13.92 g kg-1 in >2 mm fraction and 14.22 g kg-1 in <2 mm fraction. Lowest organic carbon content was in unfertilized treatment (control) in both fractions – 10.23 g kg-1 in >2 mm fractions and 10.08 g kg-1 in <2 mm fractions. The highest organic carbon <2 mm fraction quantity resulted in adequate organic matter and mineral fertilizer, which prompted humification, carbon accumulation on soil aggregate.
