Abstract: Our investigation was aimed to assess the long-term impact of reduced intensity tillage systems, straw and green manure combinations on soil organic carbon. Since 1999, a long-term field experiment has been done at the Experimental Station of Aleksandras Stulginskis University (former Lithuanian University of Agriculture). The soil of the experimental site is Epieutric Endocalcaric Endogleyic Planosol (Endoclayic, Aric, Drainic, Humic, Episiltic). Continuous long-term straw application increased soil organic carbon (SOC) content by 12.1% in top soil (0–5 cm) and 14.1 % in 15–20 cm depth compared with the plots without straw. Reduced tillage systems without primary tillage (shallow rotovating before sowing, catch cropping for green manure with rotovating, no-tillage) were even more effective in too top soil (0–5 cm depth). Compared with conventional ploughing, SOC increased by 42.6 % to 58.4 9%. Reduced tillage systems with primary tillage (shallow ploughing and shallow loosening) had no effect both on SOC and stratification process in the soil
