Effect of biochar application on physical and hydro-physical properties of soil

Popis výsledku v původním jazyce

The field experiment assessing the effect of biochar application on physical and hydrophysical properties of soil was performed at the Research station Vatín. Observed variants of biochar on the experiment were: a) without application of biochar, b) the dose of biochar was 15 t/ha, 30 t/ha and 45 t/ha. Biochar is charcoal biomass, its composition and properties depend on the input material and the process of pyrolysis. The higher dose of biochar in soil significantly decreases bulk density but porosity increases. At the depth of 15 cm, a significant difference between the porosity in the control variant (51.40%) and in the variant 45 t/ha (54.39%) was determined. As far as the effect of biochar doses on field capacity is concerned, it was found out that at the depths of 5 and 15 cm, the highest average values of field capacity were after the biochar application of 30 t/ha. In the crop rotation without manure application and clover growing, the difference in field capacity among the control variant, 15 t/ha, 30 t/ha and 45 t/ha was significant at the depth of 15 cm. In the crop rotation with manure usage and clover growing, a noticeable difference was noted between field capacity in the control variant (27.02%) and in the variant 30 t/ha (31.39%).
