In a productive vineyard, the influence of different soil management practices on labile carbon and nitrogen and its dynamics of Rendzin Leptosol was studied. In 2006, an experiment of the different management practices in a productive vineyard was established in the locality of Nitra-Dražovce (part of the Nitra City), which is in the Nitra wine-growing area (Slovakia). The following treatments were established: 1. control Co (grass without fertilizers application), 2. T (tillage), 3. T + FM (tillage + farmyard manure), 4. G + NPK3 (grass + NPK 120-55-19 kg ha-1), 5. G + NPK1 (grass + NPK 80-35-135 kg ha-1). Soil samples were collected every month (0-20 cm), during the year 2010. The results showed that labile carbon content (CL) fluctuated from 1820 to 2673 mg kg-1 and the soil management practices had a statistically significant influence on CL. The CL contents under T, T + FYM, G + NPK1 and G + NPK3 increased by 6  %, 11  %, 5  % and 13  %, respectively compared to Co treatment. During 2010, the dynamics of CL found no trend in all treatments. The highest Npot content was in Co treatment (90 mg kg-1) than in other soil management practices in a vineyard. On average, there was a smaller higher value of Npot in T + FM (78 mg kg-1) than in G + NPK3 (77 mg kg-1). During 2010, the dynamics of Npot found no trend in all treatments, except Co treatment. In Co, the Npot decline at an average speed of 4.18 mg kg-1 year-1. The CL: Npot ratios were different and their values were significant correlated only with Npot (r = -0.854, P < 0.001). During 2010, the dynamics of CL: Npot ratio showed an increasing trend with time in Co treatment.
