    Organic carbon content as affected by land management practices in monoculture of spring barley

  • Original language description

    Total organic carbon content and humic substances quality were estimated in three different straw management practices in monoculture of spring barley: straw harvested; straw incorporated; straw burning. Furthermore, the effect of minimum tillage and conventional tillage on carbon content and humic substances quality was evaluated. The long-term field experiment was established in 1969 in Žabčice at the Experimental Stationary of Mendel University in Brno (Czech Republic). The mean annual air temperature is 10.3 oC. The mean annual precipitations are 491 mm. Gleyic Fluvisol Clayic was classified according to the IUSS Working Group WRB (2014). Total organic carbon content was determined by oxidimetric titration method. The short fractionation method was used for the determination of humic substances, humic acids (HA) and fulvic acids (FA). The quality of humic substances was assessed by HA/FA ratio and by UV-VIS and infrared spectroscopy. ANOVA analysis (program StatisticaCZ12 software) and Fisher test (pLESS-THAN OR EQUAL TO0.05) were applied for data set evaluation. The correlation between carbon dynamics and straw management and tillage practices based on the longterm field experiment data set is documented. Obtained results showed also the other negative consequences of monoculture farming such as soil aberration, acidification, and a gradual decline of soil organic matter content and quality.
