Sažetak
Addition of biochar to the soil is recognized as one of the possible measures for moderation of climate change caused by the rising carbon emission to the atmosphere. Aim of this experiment is to explore the effect of addition of biochar to the soil and its effect on initial development of red clover. Experiment was set “in vitro” in a climate chamber. Length of leaves, mass of leaves, quantity of root nodules, and leaf absorption of red segment of spectrum were measured. Results show that differences between the biochar treated group and the control group in leaf mass and length were not significant. Number of root nodules in the biochar treated group was 53.3 % higher than in the control group. Absorption of red segment of spectrum in the control group was higher, suggesting higher rate of photosynthesis what is in accordance with more vigorous appearance of plants. All results show that fresh addition of biochar to the soil probably limits availability of some nutrients to plants.
