ABSTRACT
Adding charcoal (biochar) to soil has a significant effect in carbon sequestration and also considerable agronomic potential that is the primary task to find out how this potentially significant anthropogenic addition of carbon to the soil affect ecosystem functions. The aim of this study was to investigate the effect of biochar application on saturated hydraulic conductivity (Ks) and dynamics of soil moisture values (Θ) of cultivated land on locality Nitra - Malanta (Slovakia) during the growing period (GP) of 2014 and 2015. On experimental area was geodetically set out 15 plots measuring 6x4 m separated by 0.5 m bands. On these 15 plots were conducted experiment variations: control - without adding biochar (Control), B10 variant with the addition of biochar dose 10 t/ha and B20 variant with a dose of biochar 20 t/ha. During the experimental measurements the area was agriculturally used, cultivated crops were spring barley (Hordeum sativum L.) and maize (Zea mays subsp. mays). The first of the goals was to determine the effect of biochar application on Ks. The second objective was the influence of biochar on the dynamics of Θ, in response to precipitation events.
