Optimization of the Methodology for Assessment of Biochar Effect on the Growth of Model Plants
Štorková, Natálie ; Enev, Vojtěch (referee) ; Kalina, Michal (advisor)
This bachelor thesis is studying the effect of biochar on the growth of model plant and deals with the optimalization of the methods for assessing its impact. Theoretical part describes the properties and utilization of soil conditioners, special attention is focused on biochar. According to the literature research, maize (Zea mays) was chosen as a model plant for cultivation experiment and subsequently the application doses of biochar were also defined. The cultivation experiment took place in growing box under controlled illumination and irrigation. Plant dry weight weighing after cultivation, continuous measurement of plant height during the cultivation and also image analysis of the root system were used for evaluating the influence of biochar on quantitative and qualitative properties of model plants. From obtained data it can be summarized that the growth differences were influenced by the application dose, the type of biochar and also by type of soil, which was used for the cultivation experiment.

The Influence of Biochar Application on the Microbiological Characteristics of Soil
Štorková, Natálie ; Sedláček, Petr (referee) ; Kalina, Michal (advisor)
This diploma thesis is focused on the effect of Pflazenkohle biochar application into the soil and its corresponding microbial characteristics. Along with microbial characteristics (microbial functional diversity, microbial and enzymatic activity), the effect of biochar on soil physicochemical properties (pH, organic matter content, organic C and N content) and plant growth (height, above and below ground dry weight) was also assessed in this thesis. Two types of soils with low organic matter content (sandy arid soils and arenaceous chernozem) were used for the experiments. These soils were obtained after two years of cultivation with biochar at application doses 0 and 20 g-kg-1, maize (Zea mays) was selected as the model plant. The results of the cultivation experiment showed that Pflanzenkohle biochar has the potential to affect soil microbial properties, soil physicochemical properties and also plant growth, but its detectable effects on microbial characteristics of soil were limited. This was probably caused by the inappropriate biochar application form and also by the selection of soil type used for cultivation experiment. To be able to further study the effect of biochar on the soil microbial properties we considered, it would be necessary to modify the setting of cultivation experiments in the way to pronounce the statistically significant differences.
