About article:
Biochar has been increasingly used in last years for improving the characteristics of soils. Although charcoal was used in agriculture for more than 100 years, there exist new forms of biochar, specially modified to perform specific functions in the soil. In our paper, we focused on the influence of biochar with specific characteristics on the water content dynamics in the surface horizon of a cultivated soil. Two plots were studied, one without any biochar application and the other one with application of 20 t⋅ha-1 biochar. The biochar was incorporated into the soil surface layer. Soil moisture was measured by the 5TM sensors from Decagon Dev. at the 5-10 cm depth. The measurements took place directly in the field without external interruptions. Two sensors had been installed in each plot to make a comparison between them possible and to reduce the measurement error. Measuring interval was 5 minutes to capture short-term precipitation events. The soil water content on the control plot was higher than that on the plot with biochar during dry periods, but the trend has reversed after ample rains, which can be explained by the effect of macropores between the grains of biochar and the mineral soil.
